Carrie Cartwright asks: >>Can anyone give me the protocol for making 
Davidson's fixative and any information you may have on it?<<

Davidson's fixative contains 3 parts water, 3 parts ethanol, 2 parts 37% 
formalin, 1 part glacial acetic acid. (John Kiernan has recently pointed out 
that the mixture doesn't contain enough alcohol, comparing it unfavorably 
with a well mixed Martini.)

You can find extensive information about Davidson's fixative, with
