312 DISEASE IN WILD MAMMALS AND BIRDS 
Salpingitis occurred in seven cases, but there have 
been no evidences of an acute infectious disease such as is 
responsible for gleet. 
The Mammary Gland. 
This structure has been the seat of three inflammatory 
conditions and four tumors. The former occurred twice 
in nursing animals, one of which seemed to be suffering 
with distemper, another from puerperal sepsis, while the 
third case was probably traumatic. The animals were in 
order, a raccoon, a coati and a skunk. Four cancers of the 
breast have been observed, all richly cellular or glandular 
in type; none of the scirrhous variety has been 
encountered. Two of them were ulcerating and one was 
about to become so. One gave extension to the axilla and 
lung, one had penetrated the abdominal wall and grown 
around the kidney ; the remainder had not yet extended. 
The animals were Black Bear {Ursus americanus) 
(thoracic mamma with extension). Common Opossum 
(Didelphys virginiana) (two sections of breast in pouch), 
two White-footed Mice {Peromyscus leucopus) (posterior 
abdominal right gland and whole side). These animals 
were all adult but not old.
