Big: i: 
The abdominal chromaphil body of a dog stained by the intra vitam method. 
A= Aorta; Ad.= Adrenal; C=Abdominal chromaphil body; C!'=Smaller chromaphil 
body; V=Veins deeply stained by the bichromate. 
Whether the influence of the bichromate is temporary or permanent, 
that is to say, whether the tissues of the body are finally killed by the 
application of the solution I have not yet fully determined. It would 
appear a priori probable that the latter hypothesis is the true one.
