3400.0000 Mercuric-cupric 



Mercuric-cupric mixtures are excellent fixatives for small invertebrates, and have been 

 widely used for the fixation of marine forms. As histological fixatives they are inferior.

3500.0000 Mercuric-picric 



Mercuric-picric mixtures, whether acidified or modified with formaldehyde, are doubtfully 

 an improvement over mercuric alone. There seems to be no reason for incorporating picric 

 acid with its attendant disadvantages of color. These mixtures have, however, been widely 

 used in the past and are still sometimes recommended for embryological purposes.
