stamp a dermatosis as a pathological entity, but that 
they are general pathological processes which may occur 
in a number of different diseases. The disease has been 
reported in sparrows, pigeons, but never, so far as I can 
find, in turkeys. 
Observations by Dr. E. A. Schumann Upon Interesting 
Conditions Found in the Female Genital Tract. 
The cases here recorded cover the period of the last 
two years, the work in this line being interrupted by 
service in the Navy. 
No. 4763. Common Opossum (Didelphys virginiana) . 
The specimen shows an irregular tumor 4x3 cm. involving 
the floor of the marsupial pouch and one or more nipples. 
The growth in places is a smooth, nodular tumor and in 
other areas shows results of deep ulcerations. Micro- 
scopically the growth is a typical adeno-carcinoma, the 
glands in places being entirely replaced by masses of 
carcinomatous cells. In certain areas the growth has 
broken down into necrotic masses. 
No. 4798. Mandrill Baboon {Papio maimon). This 
specimen is interesting by reason of the presence of many 
larvse of a fly, species undetermined, the eggs evidently 
having gained access to the body by way of the vagina 
and the larvse having penetrated the mucous and 
muscular coats of the vagina just at the junction with 
the uterus. Many larvse are found scattered through 
the peritoneal cavity and liver. 
No. 5028. White-footed Mouse (Peromyscus 
leucopus). This animal shows a tumor of the right 
posterior mammary gland measuring 3x4 cm. The 
tumor presents no areas of ulceration, being entirely 
covered with fur. On section the growth is found to be 
a scirrhus carcinoma with many areas of hemorrhage 
scattered through the cell masses. 
No. 5037. Springbok (Gazella enchore). A very 
interesting case is that of the springbok, the animal 
dying of pneumonia while pregnant. On autopsy the 
uterus contained a normal fetus of about one-half develop- 
ment. The head of the mother shows most marked
