All specimens of _soft tissues_ designed for preservation, should first be soaked in water which is changed daily, until all blood is removed. If the weather be warm, it will be necessary to add to the water each time, either a small proportion of alcohol, or some antiseptic, as carbolic acid, chloride of zinc, corrosive sublimate, or common salt. After all blood is removed, the specimen may be put into alcohol of a strength proportionate to the size of the specimen, and then allowed to remain until thoroughly “cured.” Small specimens are dried up, shrunken and nearly spoiled in many cases, by the use of too strong alcohol, while on the other hand, large ones, by diluting the alcohol with the large amount of water contained, would be likely to spoil in a weak preparation. Large specimens, particularly in warm weather, should have deep incisions made at a few points, for the better penetration of the preserving fluid. Before being permanently put up, the specimen should be carefully trimmed, and everything interfering with the best display of the essential point removed. While either of the antiseptics mentioned above will answer for “curing” a specimen, for permanent suspension, there is no substitute for alcohol. Other fluids may preserve, but they will also become turbid, throw down a precipitate, and in cold weather are liable to freeze, while from their high specific gravity, many light specimens will float on or near the surface. If the specimen has been thoroughly “cured” before suspension, very dilute alcohol will answer for that purpose: equal parts of pure water and alcohol of ninety-five degrees, in all except the larger specimens, being abundantly strong. Delicate, light specimens will sometimes float in such a dilution, in which case it should be made stronger. The best form of anatomical jar is made with ground glass stoppers, with a hook on the under side of the latter for suspending the specimen. Although expensive, these jars, by effectually securing the alcohol from evaporation, as well as from the greater facility with which the spirits may be changed, which will sometimes be required, will give better satisfaction than any other.
