METHODS OF PRESERVING MATERIAL. Alcohol has been widely used as a preservative, but owing to the fact that it is expensive and quickly evaporates from the specimen exposed to the air, thereby rendering the parts dry and brittle, its use has been largely supplanted by formalin. Formalin, CH20, is often sold under the names of formose, formol, formine, formalosa, and formal- dehyd. It can be purchased for about thirty cents a pound. For preserving any animal or plant, the concentrated 40% formaldehyd is diluted with water in the Fig. 1.

It is evident, therefore, that one pound of formaldehyd will make about ten liters of preserving fluid. The specimens may be kept a year or two without chang- ing the formalin in ordinary stone jars with covers, but for permanent preservation the glass jar with the ground- glass cover should be used (Fig. 1). Preparation of Vascular System.—To render the vessels plainly visible and distinguish the arteries from the veins, it is advisable to inject the former with a red mass and the latter with a blue mass. These fluid masses should be of such a character as to harden in a short time after injection, so that they will not run out when the vessels are cut during dissection.
