126 DISEASE IN WILD MAMMALS AND BIRDS 
Inflammations. 
It has been the practice at this laboratory to classify 
splenitis in three ways, (1) acute diffuse splenitis — 
general congestion with perhaps small hemorrhages, 
swelling but retention of general architecture and vnth no 
undue prominence of the follicles; (2) follicular hyper- 
plasia — where tliis is the prominent gross and minute 
finding, the pulp being less pronouncedly involved; 
(3) acute splenic tumor — where the organ is greatly 
enlarged but with loss of the usual markings. Perhaps 
this separation is not warranted upon a strict etiological 
basis, and yet as we shall see it holds true fairly well in 
the toxic and infectious lesions. Moreover, from the fol- 
lowing list it is evident how the various orders call upon 
the splenic tissue in disease.
