580. Another Anthelmintic.

For thread-worms, which infest the r.e.c.t.u.m and especially the lower portion, near the orifice of the body, an injection of salt and water, in the proportion of one ounce and a half of salt to a pint, or twenty ounces of water, or of qua.s.sia chips, will generally prove effectual, and obviate the necessity of administering medicine.

583. To Prevent Pitting after Small Pox.

Spread a sheet of thin leather with the ointment of ammoniac.u.m with mercury, and cut out a place for the mouth, eyes, and nostrils. This forms what is called a mask, and, after anointing the eyelids with a little blue ointment, it should be applied to the face, and allowed to remain for three days for the distinct kind, and four days for the running variety. _Apply before_ the spots fill with matter, although it will answer sometimes even after they have become pustulous. It may be applied to any part in the same way.

584. Another Method,

and one more reliable, is that of touching every pustule, or poc, on the face or bosom with a camel-hair pencil dipped in a weak solution of lunar caustic (_nitrate of silver_), made in the proportion of two grains of nitrate of silver to one ounce of distilled water. The time for application is about the seventh day, while each pustule is filled with a limpid fluid, or before suppuration takes place, the lotion arresting that action, and by preventing the formation of matter, saving the skin from being pitted; a result that follows from the conversion of the adipose tissue into pus.
