Other Preservatives 
For histological work, special preservatives such as Bouin’s may be 
required. In the case of emergencies, the following preservatives may be 
resorted to: 
(a) strong alcoholic drinks such as whiskey, rum (best, light not dark), 
gin, arrack, or alcohol-based shaving lotion. Sake, wine, and beer 
are not sufficiently alcoholic. 
(b) strong brine solutions — one pound of salt to one gallon of water. 
(c) skinning and drying the skin, particularly in the case of very large 
specimens. Because of its extreme toxicity the use of arsenic is 
not recommended as a preservative.
