You left us a few months ago with the a.s.surance that two years would more than suffice to complete your medical studies. You chose the university which offered, as you thought, the most ample means to reach your end; and now, how is it that you look forward only with distaste to the practice of medicine? Have you reflected seriously before setting aside this profession? Indeed, we cannot consent to such a step. You would lose ground in our opinion, in that of your family, and in that of the public. You would pa.s.s for an inconsiderate, fickle young fellow, and the slightest stain on your reputation would be a mortal blow to us. There is one way of reconciling all difficulties,--the only one in my opinion. Complete your studies with all the zeal of which you are capable, and then, if you have still the same inclination, go on with your natural history; give yourself wholly up to it should that be your wish.

Having two strings to your bow, you will have the greater facility for establishing yourself. Such is your father's way of thinking as well as mine. . .Nor are you made to live alone, my child. In a home only is true happiness to be found; there you can settle yourself to your liking. The sooner you have finished your studies, the sooner you can put up your tent, catch your blue b.u.t.terfly, and metamorphose her into a loving housewife. Of course you will not gather roses without thorns; life consists of pains and pleasures everywhere. To do all the good you can to your fellow-beings, to have a pure conscience, to gain an honorable livelihood, to procure for yourself by work a little ease, to make those around you happy, --that is true happiness; all the rest but mere accessories and chimeras. . .

TO HIS MOTHER.

MUNICH, February 3, 1828.

. . .You know well to whom you speak, dear mother, and how you must bait your hook in order that the fish may rise. When you paint it, I see nothing above domestic happiness, and am convinced that the height of felicity is to be found in the bosom of your family, surrounded by little marmots to love and caress you. I hope, too, to enjoy this happiness in time. . .But the man of letters should seek repose only when he has deserved it by his toil, for if once he anchor himself, farewell to energy and liberty, by which alone great minds are fostered. Therefore I have said to myself, that I would remain unmarried till my work should a.s.sure me a peaceful and happy future. A young man has too much vigor to bear confinement so soon; he gives up many pleasures which he might have had, and does not appreciate at their just value those which he has. As it is said that the vaurien must precede the bon sujet, so I believe that for the full enjoyment of sedentary life one must have played the vagabond for a while.

This brings me to the subject of my last letter. It seems that you have misunderstood me, for your answer grants me after all just what I ask. You think that I wish to renounce entirely the study of medicine? On the contrary, the idea has never occurred to me, and, according to my promise, you shall have one of these days a doctor of medicine as a son. What repels me is the thought of practicing medicine for a livelihood, and here you give me free rein just where I wanted it. That is, you consent that I should devote myself wholly to the natural sciences should this career offer me, as I hope it may, a more favorable prospect. It requires, for instance, but two or three years to go around the world at government expense. I will levy contributions on all my senses that not a single chance may escape me for making interesting observations and fine collections, so that I also may be ranked among those who have enlarged the boundaries of science. With that my future is secured, and I shall return content and disposed to do all that you wish.

Even then, if medicine had gained greater attraction for me, there would still be time to begin the practice of it. It seems to me there is nothing impracticable in this plan. I beg you to think of it, and to talk it over with papa and with my uncle at Lausanne . . .I am perfectly well and as happy as possible, for I feed in clover here on my favorite studies, with every facility at my command. If you thought my New Year's letter depressed, it was only a momentary gloom due to the memories awakened by the day. . .

FROM HIS FATHER.

ORBE, February 21, 1828.

Your mother's last letter, my dear Louis, was in answer to one from you which crossed it on the way, and gave us, so far as your health and contentment are concerned, great satisfaction. Yet our gratification lacks something; it would be more complete had you not a mania for rushing full gallop into the future. I have often reproved you for this, and you would fare better did you pay more attention to my reproof. If it be an incurable malady with you, at all events do not force your parents to share it. If it be absolutely essential to your happiness that you should break the ice of the two poles in order to find the hairs of a mammoth, or that you should dry your shirt in the sun of the tropics, at least wait till your trunk is packed and your pa.s.sports are signed before you talk with us about it. Begin by reaching your first aim, a physician's and surgeon's diploma. I will not for the present hear of anything else, and that is more than enough. Talk to us, then in your letters, of your friends, of your personal life, of your wants (which I am always ready to satisfy), of your pleasures, of your feeling for us, but do not put yourself out of our reach with your philosophical syllogisms. My own philosophy is to fulfill my duties in my sphere, and even that gives me more than I can do. . .

The Vaudois "Society of Public Utility" has just announced an altogether new project, that of establishing popular libraries. A committee consisting of eight members, of whom I have the honor to be one, is nominated under the presidency of M. Delessert for the execution of this scheme. What do you think of the idea? To me it seems a delicate matter. I should say that before we insist upon making people read we must begin by preparing them to read usefully?. . .

TO HIS FATHER.

MUNICH, March 3, 1828.

. . .What you tell me of the "Society of Public Utility" has aroused in me a throng of ideas, about which I will write you when they are a little more mature. Meanwhile, please tell me: 1. What is this Society? 2. Of what persons is it composed? 3. What is its princ.i.p.al aim? 4. What are the popular libraries to contain, and for what cla.s.s are they intended? I believe this project may be of the greatest service to our people, and it is on this account that I desire farther details that I may think it over carefully. Tell me, also, in what way you propose to distribute your libraries at small expense, and how large they are to be. . .

I could not be more satisfied than I am with my stay here. I lead a monotonous but an exceedingly pleasant life, withdrawn from the crowd of students and seeing them but little. When our lectures are over we meet in the evening at Braun's room or mine, with three or four intimate acquaintances, and talk of scientific matters, each one in his turn presenting a subject which is first developed by him, and then discussed by all. These exercises are very instructive. As my share, I have begun to give a course of natural history, or rather of pure zoology. Braun talks to us of botany, and another of our company, Mahir, who is an excellent fellow, teaches us mathematics and physics in his turn. In two months our friend Schimper, whom we left at Heidelberg, will join us, and he will then be our professor of philosophy. Thus we shall form a little university, instructing each other and at the same time learning what we teach more thoroughly, because we shall be obliged to demonstrate it. Each session lasts two or three hours, during which the professor in charge retails his merchandise without aid of notes or book. You can imagine how useful this must be in preparing us to speak in public and with coherence; the experience is the more important, since we all desire nothing so much as sooner or later to become professors in very truth, after having played at professor in the university.

This brings me naturally to my projects again. Your letter made me feel so keenly the anxiety I had caused you by my pa.s.sion for travel, that I will not recur to it; but as my object was to make in that way a name that would win for me a professorship, I venture upon another proposition. If during the course of my studies I succeed in making myself known by a work of distinction, will you not then consent that I shall study, at least during one year, the natural sciences alone, and then accept a professorship of natural history, with the understanding that in the first place, and in the time agreed upon, I shall take my Doctor's degree? This is, indeed, essential to my obtaining what I wish, at least in Germany. You will object that, before thinking of anything beyond, I ought first to fulfill the condition. But let me say that the more clearly a man sees the road before him, the less likely he is to lose his way or take the wrong turn,--the better he can divide his stages and his resting-places. . .

FROM HIS FATHER.

ORBE, March 25, 1828.

. . .I have had a long talk about you with your uncle. He does not at all disapprove of your letters, of which I told him the contents. He only insists, as we do, on the necessity of a settled profession as absolutely essential to your financial position.

Indeed, the natural sciences, however sublime and attractive, offer nothing certain in the future. They may, no doubt, be your golden bridge, or you may, thanks to them, soar very high, but--modern Icarus--may not also some adverse fortune, an unexpected loss of popularity, or, perhaps, some revolution fatal to your philosophy, bring you down with a somersault, and then you would not be sorry to find in your quiver the means of gaining your bread. Agreed that you have now an invincible repugnance to the practice of medicine, it is evident from your last two letters that you would have no less objection to any other profession by which money is to be made, and, besides, it is too late to make another selection. This being so, we will come to an understanding in one word: Let the sciences be the balloon in which you prepare to travel through higher regions, but let medicine and surgery be your parachutes. I think, my dear Louis, you cannot object to this way of looking at the question and deciding it. In making my respects to the professor of zoology, I have the pleasure to tell him that his uncle was delighted with his way of pa.s.sing his evenings, and congratulates him with all his heart on his choice of a recreation.

Enough of this chapter. I close it here, wishing you most heartily courage, health, success, and, above all, contentment. . .

Upon this follows the answer to Louis's request for details about the "Society of Public Utility." It shows the intimate exchange of thought between father and son on educational subjects, but it is of too local an interest for reproduction here.

The Easter vacation was devoted to a short journey, some account of which will be found in the next letter. The traveling party consisted of Aga.s.siz, Braun, and Schimper, with two other students, who did not, however, remain with them during the whole trip.

TO HIS FATHER.

MUNICH, May 15, 1828.

. . .Pleasant as my Easter journey was, I will give you but a brief account of it, for my enjoyment was so connected with my special studies that the details would only be tiresome to you. You know who were my traveling companions, so I have only to tell you of our adventures, a.s.suredly not those of knights errant or troubadours.

Could these gentry have been resuscitated, and have seen us starting forth in blouses, with bags or botanical boxes at our backs and b.u.t.terfly-nets in our hands, instead of lance and buckler, they could hardly have failed to look down upon us with pity from the height of their grandeur.

The first day brought us to Landshut, where was formerly the university till it was transferred, ten years ago, to Munich. We had the pleasure of finding along our road most of the early spring plants. The weather was magnificent, and nature seemed to smile upon her votaries. . .We stopped on the way but one day, at Ratisbon, to visit some relations of Braun's, with whom we promised to spend several days on our return. Learning on our arrival at Nuremberg that the Durer festival, which had been our chief inducement for this journey, would not take place under eight or ten days, we decided to pa.s.s the intervening time at Erlangen, the seat, as you know, of a university. I do not know if I have already told you that among German students the exercise of hospitality toward those who exchange visits from one university to another is a sacred custom. It gives offense, or is at least looked upon as a mark of pride and disdain, if you do not avail yourself of this. We therefore went to one of the cafe's de reunion, and received at once our tickets for lodgings. We pa.s.sed six days at Erlangen most agreeably, making a botanical excursion every day. We also called upon the professors of botany and zoology, whom we had already seen at Munich, and by whom we were most cordially received. The professor of botany, M. Koch, invited us to a very excellent dinner, and gave us many rare plants not in our possession before, while M. Wagner was kind enough to show us in detail the Museum and the Library.

At last came the day appointed for the third centennial festival of Durer. Everything was so arranged as to make it very brilliant, and the weather was most favorable. I doubt if ever before were collected so many painters in the same place. They gathered; as if to vie with each other, from all nations, Russians, Italians, French, Germans, etc. Beside the pupils of the Academy of Fine Arts at Munich, I think that every soul who could paint, were it only the smallest sketch, was there to pay homage to the great master.

All went in procession to the place where the monument is to be raised, and the magistrates of the city laid the first stones of the pedestal. To my amus.e.m.e.nt they cemented these first stones with a mortar which was served in great silver platters, and made of fine pounded porcelain mixed with champagne. In the evening all the streets were illuminated; there were b.a.l.l.s, concerts, and plays, so that we must have been doubled or quadrupled to see everything. We stayed some days longer at Nuremberg to visit the other curiosities of the city, especially its beautiful churches, its manufactories, etc., and then started on our return to Ratisbon. . .

First Important Work in Natural History.

Spix's Brazilian Fishes.

Second Vacation Trip.

Sketch of Work during University Year.

Extracts from the Journal of Mr. d.i.n.kel.

Home Letters.

Hope of joining Humboldt's Asiatic Expedition.

Letter concerning it from Cuvier.

It was not without a definite purpose that Aga.s.siz had written to his father some weeks before, "Should I during the course of my studies succeed in making myself known by a distinguished work, would you not then consent that I should study for one year the natural sciences alone?" Unknown to his parents, for whom he hoped to prepare a delightful surprise, Aga.s.siz had actually been engaged for months on the first work which gave him distinction in the scientific world; namely, a description of the Brazilian fishes brought home by Martius and Spix from their celebrated journey in Brazil. This was the secret to which allusion is made in the next letter. To his disappointment an accident brought his undertaking to the knowledge of his father and mother before it was completed.

He always had a boyish regret that his little plot had been betrayed before the moment for the denouement arrived. The book was written in Latin and dedicated to Cuvier.* (* "Selecta genera et species piscium quos collegit et pingendos curavit Dr. J.W. de Spix". Digessit, descripsit et observationibus ill.u.s.travit Dr. L.

Aga.s.siz.)

TO HIS BROTHER.

MUNICH, July 27, 1828.

. . .Various things which I have begun keep me a prisoner here.

Probably I shall not stir during the vacation, and shall even give up the little trip in the Tyrol, which I had thought of making as a rest from occupations that bind me very closely at present, but from which I hope to free myself in the course of the holidays.

Don't be angry with me for not telling you at once what they are.

When you know, I hope to be forgiven for keeping you so long in the dark. I have kept it a secret from papa too, though in his last letter he asks me what is my especial work just now. A few months more of patience, and I will give you a strict account of my time since I came here, and then I am sure you will be satisfied with me. I only wish to guard against one thing: do not take it into your head that I am about to don the fool's cap suddenly and surprise you with a Doctor's degree; that would be going a little too fast, nor do I think of it yet. . .I want to remind you not to let the summer pa.s.s without getting me fishes according to the list in my last letter, which I hope you have not mislaid. You would give me great pleasure by sending them as soon as possible. Let me tell you why. M. Cuvier has announced the publication of a complete work on all the known fishes, and in the prospectus he calls on such naturalists as occupy themselves with ichthyology to send him the fishes of the country where they live; he mentions those who have already sent him collections, and promises duplicates from the Paris Museum to those who will send him more. He names the countries also from which he has received contributions, and regrets that he has nothing from Bavaria. Now I possess several specimens of all the native species, and have even discovered some ten not hitherto known to occur here, beside one completely new to science, which I have named Cyprinus uranoscopus on account of the position of the eyes, placed on the top instead of the sides of the head,--otherwise very like the gudgeon. I have therefore thought I could not better launch myself in the scientific world than by sending Cuvier my fishes with the observations I have made on their natural history. To these I should like to add such rare Swiss species as you can procure for me. So do not fail.

FROM HIS BROTHER.

NEUCHATEL, August 25, 1828.

. . .I received in good time, and with infinite delight, your pleasant letter of July 27th. Its mysteries have however been unveiled by Dr. Schinz, who came to the meeting of the Natural History Society in Lausanne, where he met papa and my uncle, to whom he p.r.o.nounced the most solemn eulogiums on their son and nephew, telling them at the same time what was chiefly occupying you now. I congratulate you, my dear brother, but I confess that among us all I am the least surprised, for my presentiments about you outrun all this, and I hope soon to see them realized. In all frankness I can a.s.sure you that the stoutest antagonists of your natural history schemes begin to come over to your side. Among them is my uncle here, who never speaks of you now but with enthusiasm.

What more can be said? I gave him your letter to read, and since then he has asked me a dozen times at least if I had not forgotten to forward the remittance you asked for, saying that I must not delay it. The truth is, I have deferred writing till the last moment, because I have not succeeded in getting your fishes, and have always been hoping that I might be able to fulfill your commission. I busied myself on your behalf with all the zeal and industry of which I was capable, but quite in vain. The devil seemed to be in it. The season of Bondelles was over two months ago, and there are none to be seen; as to trout, I don't believe one has been eaten in the whole town for six weeks. I am forever at the heels of the fishermen, promising them double and treble the value of the fish I want, but they all tell me they catch nothing except pike. I have been to Cudrefin for lampreys, but found nothing. Rodolphe* (* An experienced old boatman.) has been paddling in the brook every day without success. I went to Sauge, --no eels, no anything but perch and a few little cat-fish. Two mortal Sundays did I spend, rod in hand, trying to catch bream, chubs, etc. I did get a few, but they were not worth sending. Now it is all over for this year, and we may as well put on mourning for them; but I promise you that as soon as the spring opens I will go to work, and you shall have all you want. If, in spite of everything, your hopes are not realized, I shall be very sorry, but rest a.s.sured that it is not my fault. . .

TO HIS SISTER CECILE.

MUNICH, October 29, 1828.

. . .I have never written you about what has engrossed me so deeply; but since my secret is out, I ought not to keep silence longer. That you may understand why I have entered upon such a work I will go back to its origin. In 1817 the King of Bavaria sent two naturalists, M. Martius and M. Spix, on an exploring expedition to Brazil. Of M. Martius, with whom I always spend my Wednesday evenings, I have often spoken to you. In 1821 these gentlemen returned to their country laden with new discoveries, which they published in succession. M. Martius issued colored ill.u.s.trations of all the unknown plants he had collected on his journey, while M.

Spix brought out several folio volumes on the monkeys, birds, and reptiles of Brazil, the animals being drawn and colored, chiefly life-size, by able artists. It had been his intention to give a complete natural history of Brazil, but to the sorrow of all naturalists he died in 1826. M. Martius, desirous to see the completion of the work which his traveling companion had begun, engaged a professor from Erlangen to publish the sh.e.l.ls, and these appeared last year. When I came to Munich there remained only the fishes and insects, and M. Martius, who had learned something about me from the professors to whom I was known, found me worthy to continue the work of Spix, and asked me to carry on the natural history of the fishes. I hesitated for a long time to accept this honorable offer, fearing that the occupation might withdraw me too much from my studies; but, on the other hand, the opportunity for laying the foundation of a reputation by a large undertaking seemed too favorable to be refused. The first volume is already finished, and the printing was begun some weeks ago. You can imagine the pleasure I should have had in sending it to our dear father and mother before they had heard one word about it, or knew even of the proposition. But I hope the premature disclosure of my secret (indeed, to tell the truth, I had not imposed silence on M. Schinz, not dreaming that he would see any one of the family) will not diminish your pleasure in receiving the first work of your brother Louis, which I hope to send you at Easter. Already forty colored folio plates are completed. Will it not seem strange when the largest and finest book in papa's library is one written by his Louis? Will it not be as good as to see his prescription at the apothecary's? It is true that this first effort will bring me in but little; nothing at all, in fact, because M. de Martius has a.s.sumed all the expenses, and will, of course, receive the profits.

My share will be a few copies of the book, and these I shall give to the friends who have the first claim.

To his father Aga.s.siz only writes of his work at this time: "I have been very busy this summer, and I can tell you from a good source (I have it from one of the professors himself) that the professors whose lectures I have attended have mentioned me more than once, as one of the most a.s.siduous and best informed students of the university; saying also that I deserved distinction. I do not tell you this from ostentation, but only that you may not think I lose my time, even though I occupy myself chiefly with the natural sciences. I hope yet to prove to you that with a brevet of Doctor as a guarantee, Natural History may be a man's bread-winner as well as the delight of his life. . ."

In September Aga.s.siz allowed himself a short interruption of his work. The next letter gives some account of this second vacation trip.
