affinity for nuclear stains such as hsematoxylin, safranin, etc. 

 These granules also reduce chloride of gold and become green 

 in contact with ferric chloride. But their most characteristic 

 reaction is with chromium salts. In the presence of any of 

 these, or of chromic acid itself (in many instances, at any rate),

the cells become stained so as to assume any tint between a 

 bright yellow and a dark brown. This reaction was discovered 

 by Henle in the year 1865. Stilling, who discovered the cells 

 having the same reaction along the sympathetic and in the 

 carotid gland of mammals, called them, the corpuscles which 

 they formed, and the medulla of the adrenal, " chromophil."
