corpuscles, which he previously supposed to be identical with 

 Waldeyer's plasma cells, but which he is now inclined to re- 

 gard as a distinctive group of bodies. They are characterized 

 by a special power of intense coloration in specimens treated 

 with certain of the aniline dyes. Red and violet colors appear 

 to be best suited to reveal the presence of these bodies, called 

 by Ehrlich granular cells. Acetic acid produces a diffuse 

 staining of the nucleus in these aniline stained cells. At the 

 same time the conspicuous granules lose their color. The same 

 author also states that the granular cells commonly found in 

 such great abundance in inflammatory processes are not modi- 

 fied leucocytes, but are derived from the fixed connective- 

 tissue corpuscles. 



According to Ravogli, the connective-tissue corpuscles of 

 the corium and subcutaneous tissue are branching cells, whose 

 processes unite to form anastomoses. With advancing age these 

 cells undergo structural alterations, and their processes begin 

 to form reticula of elastic tissue. Simultaneously with this 

 metamorphosis the cell-bodies are said to become flattened, 

 elongated, and united in longitudinal rows. At length the cells 

 as well as their processes are transformed into ordinary elastic 

 tissue.
