The "gla.s.s houses" of America differ entirely from what we understand by the name here; indeed, I never saw such a thing there, either by chance, accident, or design--for chance has no "gla.s.s houses" in America, only an agency; there are no accidental gla.s.s houses, and the operating rooms built by design are not "gla.s.s houses" at all.

The majority of the houses in New York and other American cities are built with nearly flat roofs, and many of them with lessening storeys from front to back, resembling a flight of two or three steps. In one of these roofs, according to circ.u.mstances, a large "skylight" is fixed, and pitched usually at an angle of 45, and the rooms, as a rule, are large enough to allow the sitter to be placed anywhere within the radius of the light, so that any effect or any view of the face can easily be obtained.

The light is not any more actinic there than here in good weather, but they have a very great deal more light of a good quality _all the year round_ than we have.

The operators work generally with a highly bromized collodion, which, as a rule, they make themselves, but not throughout. They buy the gun-cotton of some good maker--Mr. Tomlinson, agent for Mr. Cutting, generally supplied the best--then dissolve, iodize, and bromize to suit their working.

Pyrogallic acid as an intensifier is very little used by the American operators, so little that it is not kept in stock by the dealers.

Requiring some once, I had quite a hunt for it, but found some at last, stowed away as "Not Wanted," in Messrs. Anthony's store. The general intensifier is what they laconically call "sulph.," which is sulphuret of pota.s.sium in a very dilute solution, either flowed over the plate, or the plate is immersed in a dipping bath, after fixing, which is by far the _pleasantest_ way to employ the "sulph. solution." Throwing it about as some of them do is anything but agreeable. In such cases, "sulph."

was the first thing that saluted my olfactories on putting my head inside one of their "dark rooms."

Up to 1860 the American photographic prints were all on plain paper, and obtained by the ammonia nitrate of silver bath, and toned and fixed with the hyposulphite of soda and gold. The introduction of the cartes-de-visite forced the operators to make use of alb.u.menized paper; but even then they seemed determined to adhere to the ammonia process if possible, for they commenced all sorts of experiments with that volatile accelerator, both wet and dry, some by adding ammonia and ether to an 80-grain silver bath, others by fuming, and toning with an acetate and gold bath, and fixing with hypo afterwards.

With the following "musings" on "wrappers" (not "spirit wrappers," nor railway wrappers, but "carte-de-visite wrappers"), I shall conclude my rambles among the galleries of New York. Wrappers generally afford an excellent opportunity for ornamental display. Many of the wrappers of our magazines are elegantly and artistically ornamented. Nearly every pack of playing cards is done up in a beautiful wrapper. The French have given their attention to the subject of "carte-de-visite wrappers," and turned out a few unique patterns, which, however, never came much into use in this country. The Americans, more alive to fanciful and tasteful objects of ornamentation, and close imitators of the French in these matters, have made more use of carte-de-visite wrappers than we have.

Many wrappers of an artistic and literary character are used by the photographers in America--some with ornamental designs; some with the address of the houses tastefully executed; others with poetical effusions, in which the cartes-de-visite are neatly wrapped up, and handed over to the sitter.

Surely a useful suggestion is here given, for wrappers are useful things in their way, and, if made up tastefully, would attract attention to the photographic establishments that issue them. Photography is so closely allied to art that it is desirable to have everything in connection with it of an elegant and artistic description. The plain paper envelopes--gummed up at the ends, and difficult to get open again--are very inartistic, and anything but suitable to envelop such pretty little pictures as cartes-de-visite. Let photography encourage art and art manufactures, and art will enter into a treaty of reciprocity for their mutual advancement.--_Photographic News_, 1865.

TO DUBLIN AND BACK, WITH A GLANCE AT THE EXHIBITION.

The bell rings; a shrill shriek; puff, puff goes the engine, and we dart away from the station at Euston Square, provided with a return ticket to Dublin, issued by the London and North Western Railway, available for one month, for the very reasonable charge of 3, first-cla.s.s and cabin; 2 7s. 6d. second cla.s.s and cabin; or forty shillings third cla.s.s and steerage, via Holyhead. These charges include steamboat fare and steward's fee. The Exhibition Committee have made arrangements with the railway companies to run excursion trains once a fortnight at still lower rates; twenty-one shillings from London to Dublin and back, and from other places in proportion. This ticket will be good for a fortnight, and will ent.i.tle the holder to another ticket, giving him two admissions to the Exhibition for one shilling. With the ordinary monthly ticket, which is issued daily, it is quite optional whether you go by the morning or evening train; but by all means take the morning train, so that you may pa.s.s through North Wales and the Island of Anglesea in daylight. Pa.s.sing through England by Rugby, Stafford, Crewe, and Chester, nothing remarkable occurs during our rapid run through that part of the country. But an "Irish Gentleman," a fellow traveller, learning our destination, kindly volunteered to enlighten us how we could best see Dublin and its lions in the shortest possible time, and advised us by all "manes" not to "lave" Dublin without seeing "Faynix Park," and taking a car drive to Howth and other places round the "Bee of Dublin." Accordingly we agreed to take his advice; but as our primary object in visiting Dublin is to see the Exhibition, we will first attend to that on our arrival in the Irish capital; and if, after that, time will permit, the extraneous lions will receive our attention. First of all, we must describe how we got there, what we saw on the way, and what were our impressions on entering Dublin Bay.

As we said before, nothing particular occurred during our journey through England to excite our attention or curiosity; but on pa.s.sing into Wales--Flintshire--our attention is at once arrested by the difference of the scenery through which we pa.s.s. Soon after leaving Chester, we get a sight of the river Dee on our right, and continue to run down by its side past Flint, Bagillt, Holywell, and Mostyn, then we take a bend to the left and skirt a part of the Irish Channel past Rhyl, Abergele, and Colwyn to Conway, with its extensive ruins of a once vast and n.o.ble castle, through, under, and about the ruins of which the double lines of iron rails twist and twine and sinuously encoil themselves like a boa constrictor of civilization and demolisher of wrecks, ruins, and vestiges of the feudal ages and semi-barbarism. Our iron charger dashes up to the very walls of the ancient stronghold, close past the base of a tower, and right under the hanging ruins of another, which is in truth a "baseless fabric," but no "vision," for there it is suspended in mid air, a fabric without a base, holding on to its surroundings by the cohesive power of their early attachments. We rush into the very bowels of the keep itself, snorting and puffing defiance to the memoried sternness of the grim warriors who once held the place against all intruders. Anyone who has not had an opportunity before of visiting North Wales should keep a sharp look-out right and left, and they will get a peep at most of the princ.i.p.al places on the route: the Welsh mountains on the left, their summits illuminated by the sun sinking towards the west, and the ma.s.s of them thrown into shadow in fine contrast.

Now we are at Penmaenmawr, that pretty little watering place, with its neat-looking houses snugly nestling in the laps of the hills, and we pa.s.s along so close to the sea, we can feel the spray from the waves as they break on the sh.o.r.e.

Pa.s.sing Llanfairfechan and Aber we are at Bangor, and almost immediately afterwards make a dive into the long, dark chamber of the Tubular Bridge, with a shriek and rumbling rattle that is almost startling. In a few seconds we are out into the daylight again, and get a view of the Straits of Menai; and on the right-hand side, looking back, get an excellent sight of the Tubular Bridge. At the moment of our pa.s.sing, a ship in full sail was running before the wind through the Straits, which added considerably to the picturesque beauty of the scene. On the left a fine view of the "Suspension Bridge" is obtained. We are soon past Llanfair, and across that bleak and desolate part of the island of Anglesea between the Menai Straits and the Valley. Arriving at Holyhead, we go on board the steamer which is to carry us across the Channel to Dublin. The boat not starting immediately, but giving us a little time to look around, we go on sh.o.r.e again, and saunter up and down the narrow hilly streets of Holyhead, listening in vain for the sound of a word spoken in our mother tongue. Not a word could we hear, not a word of English could we get without asking for it. The most of the people can speak English with a foreign-like accent, but you seldom hear it unless you address them in English. Even the urchins in the streets carry on their games and play in the Welsh and unintelligible sounds resembling language.

We also had time to examine the stupendous breakwater which the Government is building at Holyhead to form a harbour of refuge. The wall is a mile and three-quarters in length, and of immense thickness, in the form of three terraces, the highest towards the sea. At one place we noticed that the solid slatey rocks were hewn and dressed into shape, and thus formed part of the wall itself, a mixture of Nature's handiwork and the work of man.

Time to go on board again, and as the wind was blowing rather strong, we expected to have a rough voyage of it; and sure enough we had, for we were scarcely clear of the sheltering kindliness of the sea wall and the "north stack" till our vessel began to "pitch and toss," and roll and creak, and groan in agony; and so highly sympathetic were we that we did the same, and could not help it, do what we could. Strong tea, brandy and water, were all no use. Down we went, like prostrate sinners as we were, on our knees, with clasped hands, praying for the winds and the waves "to be still;" but they did not heed our prayer in the least, and kept up their inhumane howling, dancing, and jumbling until, by the time we reached the middle of the Channel, we began to think that the captain had lost his course, and that we were somewhere between Holyhead and purgatory, if not in purgatory itself, being purged of our sins, and becoming internally pure and externally foul. But we discovered that we, and not the captain, had lost the course and the even tenour of our way, for we fancied--perhaps it was only fancy--that we could hear him humming s.n.a.t.c.hes of old song, among them "Oh! steer my bark to Erin's Isle!" and soon the mountains of Wicklow are in sight. As we near, and get under the lee of the land--for it was a stiff "sou'-wester" that bothered us--our sensations and feelings begin to improve, and we pick ourselves up out of the mire, and turn our eyes eagerly and hopefully towards the Emerald Isle, and Dublin Bay more particularly.

As we approach the Bay, the Carlingford Hills can be seen on the right, and a little more southwards Lambay and Ireland's Eye. The latter island is rugged and precipitous, seaward, in the extreme--a barren and desolate-looking spot, possessing an unenviable notoriety on account of the murder of a lady by her husband having been committed there a few years ago: Howth, the light-house, and the Bailey Rock, where the _Queen Victoria_ steamer was wrecked, now attract our attention. And, as nearly as we can remember, these are the most striking features on the north side of the Bay. On the south the Harbour of Kingstown is distinctly visible, and we saw the mail steamer which crosses from Holyhead to Kingstown, a distance of sixty miles, in three and a half hours, blowing off her steam. By paying a little extra you can cross in the mail steamers, if you wish, but it is not worth while paying the difference, as the ordinary steamers cross from Holyhead to Dublin in about five and a half hours. All round the south side of the Bay we could trace the Kingstown and Dublin railway, which is the oldest line but one in the United Queendoms of Great Britain and Ireland. An obelisk commemorates the visit of the last of the four Georges to Ireland in 1821. Right over Kingstown the Killinny Hills are to be seen, and all along the water-line the Bay is studded with pretty little villas, and the scene is truly beautiful. If possible, arrange your entrance into the Bay of Dublin in the early morning, for then the sun, rising in the east, lights up the subjects to the very best advantage, and throws a charm about them which they do not exhibit at any other time of the day. By waiting at Holyhead for the early morning boat you can easily manage this. But now we are at the North Wall, and on landing are besieged by Carmen to have a "rowl," and jumping on to one of those light, odd-looking, jaunting cars which are one of the inst.i.tutions of the country, we are "rowled" up the North Wall for nearly a mile, past the Docks, over the drawbridges, and past the Custom House--a large stone building, too large for the business of the port--along Carlisle Bridge, down Westmoreland Street, past the Bank of Ireland--once the Houses of Parliament--and up Dame Street, leaving the College on our left, and pa.s.sing King William's statue, representing a mounted Roman with _gilded_ laurels and ornamental toga, we arrive at Jury's Hotel, a commercial and family house of superior arrangements which was well recommended to us before we left London; and here we rest.

After breakfast, and having made ourselves internally and externally comfortable, we start for the Exhibition, which is within easy walking distance of the hotel; but the car fares are so very moderate that we prefer a "rowl." The fare is sixpence a "set down;" that is, you may ride from one end of the city to the other for sixpence, but if you get off to post a letter, or buy an umbrella to keep the rain off--for the cars have no covering--that is a "set down;" and so every time you get down and get up again you have sixpence to pay, no matter how short the distance you are taken each time. So we hailed a car at the door of the hotel, determined to be "rowled" to the Exhibition for sixpence each. We go down Dame Street, across College Green, up Grafton Street, along the west and south sides of St. Stephen's Green or Square to Earlsfort Terrace and the princ.i.p.al entrance to the Dublin Exhibition, which occupies the site of what was formerly Coburg Gardens.

Arriving at the entrance-hall, we pay our admission fee, and on pa.s.sing the registering turnstiles we are at once in the sculpture hall on the ground floor, the contents of which we shall notice more particularly by-and-by. Pa.s.sing through the Sculpture Hall we are within the western transept, or winter garden portion of the Exhibition. This transept is 500 feet long and of lofty proportions, with galleries on each side, and tastefully hung with the banners and flags of the nations exhibiting.

The northern court is about 300 feet long, also of iron and gla.s.s, with galleries running round both sides similar to the western transept. The ground floor and part of the galleries of the northern court are devoted to the productions of the United Kingdom. On the north side of the northern court is the machinery department, both at rest and in motion.

Here machines of the most delicate and ponderous nature are at work.

There a forge-hammer daintily cracking nuts, or coming down with a crushing force at the will of the attendant. In another place a delicate curving-machine is at work; and another can be seen making steel pens.

There are high pressure engines, sewing machines, and photographic rolling-presses. Indeed, there is almost everything to be seen and everything going on that is instructive, edifying, and amusing. The Exhibition building is small, but well arranged and compact, and partakes of the character of an art and industrial exhibition and place of amus.e.m.e.nt and recreation, like our Crystal Palace at Sydenham, with ornamental gardens and archery grounds attached. The gardens are small--a little larger than the area of the building itself--but most tastefully laid out. And there are fountains and grottoes, and rockeries and cascades, with flowers growing about them, which give the whole place a pleasant, healthy, and delightful appearance. Stepping out of the western transept into the gardens, we found the band of the 78th Highlanders playing in the centre, and their pipers walking about the grounds ready to take up the strains of music in another key, for presently we saw them marching about, playing "Hielan' Skirls," and sounding the loud pibroch, with a five-bag power that was more stunning than the nocturnal wailings of a dozen or two Kilkenny cats. The directors furnish music and offer other inducements to secure a good attendance, and their efforts ought to be successful, and it is to be hoped they will be so.

On the first day of our visit there was a grand archery meeting, and the turn-out of Dublin belles was double in numbers. There was a large attendance of bowmen, too, and belles and beaux were banging away at the targets most unmercifully in keen contest for the prize; whether it was a medal, a ring, or an heiress, we could not learn; but if nothing more than the privilege of entering the lists against such lovely compet.i.tors, the bowmen ought to have been satisfied; but we don't suppose they were, for men are both ambitious and avaricious, and probably some of them hoped to win a prize medal, kill a beauty, and catch an heiress all at once, with one swift arrow sent whizzing and quivering into the very heart and gilded centre of the gaily-painted target.

Perched up on the top of the cascades we noticed a double sliding-front stereoscopic camera, and doubtless Mr. York was busy photographing the scene we have been describing--impressions of which the London Stereoscopic Company will probably issue ere long. We must, however, leave this gay scene and turn our attention to other things, certainly not more attractive; but duty calls us away from beauty, and we must submit.

Re-entering the Exhibition building, we seek the photographic department, which we readily find on the ground floor, between the music hall and the first-cla.s.s refreshment-room. Entering from the Belgian department in the western transept, we find three rooms in the main building devoted to the exhibition of photographs, and a lobby between the rooms pretty well filled with apparatus. To Sir J. Jocelyn Coghill are photographers indebted for obtaining so much s.p.a.ce for their works, and in such a get-at-able situation; but it is a pity the rooms are not better lighted. Many of the pictures on the screens are very indistinctly seen, and some are in dark corners scarcely to be seen at all.

The foreign department, which is the first room we enter, is mainly made up of reproductions of old and modern engravings, and copies of drawings and paintings. One very remarkable photograph on the wall of this room is an immense magnification of a flea, by A. Duvette. What a subject for the camera!--one that suggests in sporting phraseology something more than the "find," the "chase," and the "death."

A panoramic view of Rome, by M. Petagna, is a great achievement in panoramic photography. There are seven impressions from 15 by 12 plates, all carefully joined, and of equal tone. The point of view is "Ta.s.so's Oak," and the panorama gives us an excellent idea of Rome at the present day.

The British part of the Photographic Exhibition in Dublin might be very properly denominated an enlargement of the Society's exhibition now open in Conduit Street, London. Nearly all the princ.i.p.al exhibitors there have sent duplicates of their chief works to the Dublin Exhibition.

There is Robinson's beautiful picture of "Brenda," his "May Gatherers,"

"Sunshine," "Autumn," "Somebody Coming," "Bringing home the May," &c., all old and familiar pictures, every one of which we have seen before.

Robinson himself in his study--a beautiful piece of photography, even to his black velvet coat. Blanchard also repeats his "Zealot," and other subjects, and sends a frame full of his exquisite stereographs. England also sends some of his charming stereoscopic pictures of Switzerland and Savoy. Bedford's contribution is much the same as his pictures in the London exhibition. Among them are his lovely Warwickshire pictures.

Wet-plate photography is well represented, both in landscape, portraiture, and composition. Among the latter, Rejlander is most prominent. One frame containing some pictures showing the "expression"

of the hands, ill.u.s.trates Rejlander's artistic knowledge and ability more than many of his other pictures. None but a thoughtful and accomplished artist could have disposed of those members in such a skilful manner. His pictures of "Grief," "The Mote," "The Wayfarer,"

"'Tis Light within--Dark without," and his "Home, Sweet Home," reveal exquisite feeling in his treatment of such subjects. Thurston Thompson also exhibits some of his fine reproductions of Turner. There is "Crossing the Brook," and "Childe Harold's Pilgrimage;" but a much larger collection of these beautiful copies of Turner's pictures are now on view at Marion's, in Soho Square.

Dry plate photography is exemplified in all its phases, from the oldest form of alb.u.men alone, to the latest modifications with collodion, collodio-alb.u.men, Fothergill, tannin, malt, &c. The most prominent and largest contributor to this department is Mr. Mudd. In addition to the duplicates in the London Exhibition, he sends a few others, the most remarkable of which is a large view of "Borrowdale," a n.o.ble picture, exquisitely treated, showing ma.s.ses of light and shade and pleasing composition which stamp it at once as a work of art.

Mr. G. S. Penny exhibits some very fine examples of the tannin and malt process. They are soft and delicate, and possess sufficient force to give powerful contrasts when necessary. Mr. Bull's tannin and malt pictures are also very good; his "Menai Bridge" particularly so.

The amateur photographers, both wet and dry, make a good show. And among the Irish followers of our delightful art are Sir J. J. Coghill, who exhibits twelve very pretty views of the neighbourhood of Castletownsend. Dr. Hemphill, of Clonmel, also exhibits a variety of subjects, many of them pretty compositions and excellent photography.

Dr. Bailey, of Monaghan, contributes both landscapes and portraits of very good quality. Mr. T. M. Brownrigg shows seventeen photographs all excellent examples of the wet collodion process. Many of them are exquisite bits of photography, and evince an amount of thought and care in selecting the best point of view, arranging the lines of the subject, and catching the best effect of light so as to make them pictures, which is seldom attended to by professional photographers.

Amongst the Irish professional photographers in landscape work, Mr. F.

Mares, of Dublin, stands pre-eminent. His pictures of Killarney, and views in the county of Wicklow, are very beautiful, and give evidence of a cultivated eye and artistic taste in the selection of his subjects and points of view. There are other excellent views and architectural subjects by Irish photographers; but we are sorry to observe some that really ought not to have been admitted. They are not even average photography, being utterly dest.i.tute of manipulative skill, and as deficient in art-excellence as they can well be.

One branch of landscape, or, we should say, marine photography, is without compet.i.tion. We refer to those exquisite and charming transparencies by Mr. C. S. Breese. His moonlight effect is wonderfully managed; the water looks "alive," and the moonlight is dancing on the waves just as we have seen it far away upon the sea. His "Breaking Wave"

is marvellous, coming to sh.o.r.e with its cavernous curl; we almost fancy we hear its angry howl as it dashes itself into foam on the beach. We have seen such a wave sweep the deck of a ship before now, and know well with what a ponderous weight and velocity it comes; and we wonder the more at Mr. Breese's success in catching the wave in such a position. We cannot, however, speak so highly of the "Sunlight" effects by the same artist. The transparencies as photographs are inimitable; but there is colour introduced into the skies which ought to have been taken up by the rocks, and so carried into the foregrounds of the pictures, to be natural. Such warm skies and cold middle distances and foregrounds are too antagonistic for the harmony of nature.

In portraiture, our Irish brethren of the camera contribute somewhat liberally. In that branch we noticed the works of Messrs. Robertson and Co., S. Lawrence, and G. Schroeder, of Grafton Street; Millard and Robinson, Nelson and Marshall, and S. Chancellor, of Sackville Street, Dublin. T. Cranfield, Grafton Street, also exhibits some photographs beautifully coloured in oil.

The most eminent English photographers also show up well. We saw the well-known works of Mayall, Silvy, Claudet, Maull and Co., and others, eminent in plain photography. Messrs. Lock and Whitfield exhibit a Royal case of exquisitely coloured photographs of the Prince and Princess of Wales, and Prince Albert Victor. Mr. G. Wharton Simpson also exhibits a few specimens of his beautiful collodio-chloride of silver printing process. There are some lovely specimens of that process with such a frightfully ugly name, but which, in plain parlance, are pictures on opal gla.s.s, though Mr. Helsby has christened them "Helioaristotypia miniatures." As a set-off to this, the next dry process that is discovered should be called "Hydrophobiatypia."

In amateur portraiture, Mr. H. Cooper, Jun., exhibits a large number of his clever life studies, as well as those quiet and charming representations of his friends in their habits as they live.

Solar camera enlargements are very numerously contributed. Mr. Claudet sends some good pictures enlarged by solar camera, and developed with gallic acid. Mr. Salomon also has some very good examples of enlarging.

Dr. D. Van Monckhoven is an exhibitor of the capabilities of his direct printing camera. Mr. Mayall exhibits two series of very interesting enlargements by the Monckhoven camera, printed direct on alb.u.menized paper; one is Tennyson, in eight different sizes, from a one-ninth to a life-size head on a whole sheet of paper; of the other, Captain Grant, there are seven similar pictures. These photographs are all bold and vigorous and uniform in colour, and come nearer to our idea of what an enlargement should be than anything we have yet seen. Of the two, that of the Poet-Laureate is the best; the other is harsher, which is in all probability due to the difference in the subjects themselves. We can easily imagine that the face of Captain Grant, bronzed and weather-beaten as it must be, will present more obstacles to the obtaining of a soft negative than that of Tennyson. Specimens of photo-sculpture are also to be seen at the Dublin Exhibition, many of which are very pretty and life-like statuettes; but some of the figures seem much too large in the _busts_, and the plinths on which the figures of ladies stand are in very bad taste; being diminishing beads of a circular form, they suggest the idea of a huge crinoline just dropped.

Nearly all the denominations of photography have their representative forms and impressions in this Exhibition; and the history of the art, from the early days of the Daguerreotype to the latest vagary of the present day, may be traced in the collection of photographs spread before you on the walls and screens of the Dublin International Exhibition. There is the Daguerreotype, the Ambrotype, and the collodiotype, which ought to have been known as the Archertype; for the wet collodion process, although it is the most important of all the discoveries in photography that have been made since the first pictures were obtained by Wedgwood, is without a name conferring honour on the man who first applied collodion to photography. Archer's name is generally a.s.sociated with it, but without taking that definite and appellative form it ought to. We know that another claimant has been "cutting in" for the honour, but unless that claim can be "backed up" by data, we are not disposed to believe that it was anterior to 1851--the year of the first exhibition; at that date we know that Mr. Archer took photographs on collodionized gla.s.s plates. Then why should we not honour Archer as the French honoured Daguerre, and call the wet collodion process the Archertype?

In printing and toning, there are samples of nearly all the formulae that have been discovered since the days of printing on plain salted paper and fixing in "hypo" only. There are prints on plain paper and on alb.u.menized paper, toned and fixed in every conceivable way. There are prints on gla.s.s, porcelain, and ivory; prints in carbon, from the negative direct; and impressions in printer's ink from plates, blocks, and lithographic stones, which have had the subjects transferred to them by the aid of photography. There are Wothlytypes, and Simpsontypes, and Tooveytypes, and all the other types that have sprung from a desire to introduce novelties into the art.

In graphs and the various forms and fanciful applications of photography to portraiture, &c., there are stereographs and micrographs, and the old-fashioned "sit-on-a-chair" graphs, the "stand-not-at-ease" graphs, the "small carte" graph, the "large carte" graph, the "casket gem"

graph, the "magnesium" graph, the "cameo" graph, the "double-stupid"

graph, and the latest of all novelties, the "turn-me-round" graph. The latter is a great curiosity, and must have been suggested by a recollection of that "scientific toy" of ancient manufacture with which we used to awaken the wonder of our little brothers and sisters at Christmas parties when we were boys, by twirling before their astonished eyes a piece of cardboard with a bird painted on one side and a cage on the other, both pictures being seen at the same time during the rapid revolution of the card.

In apparatus there is not much to talk about, the Pantascopic camera being the chief novelty. There are several of the manufacturers exhibiting in the photographic department, but we could not reconcile ourselves to the circ.u.mstance of Mr. Dallmeyer not exhibiting in the right place. His name is honoured by photographers, and he should have honoured Photography by going in under her colours. If he must go to the "scientific department," he ought to have gone there with his scientific instruments alone, and shown his photographic apparatus in the place a.s.signed for that purpose. True, he makes a handsome show, but that does not atone for his mistake. Photographers are queer animals--jealous of their rights, and as sensitive to slight as their plates are to light; and we fear we are ourselves not much better. A large majority of photographers stand by Mr. Dallmeyer, and very justly believe in his 1 and 2 B's as shippers do in A 1's at Lloyd's; and _his_ stand should have been in the photographic department.

In other parts of the Exhibition building there are various subjects highly interesting to photographers.

The chemical department has its attractions in samples of collodio-chloride of silver, prepared by Messrs. Mawson and Swan, for the opal printing process and the Simpsontype. Specimens of each type are also to be seen there; and there are other chemicals used in photography, even to dextrine and starch: the purity of the latter is known by the size and length of its crystals.
