the vipper lobe of the left kidney. The section shows an alveolar sarcoma. 
Some of the cells, particularly in the freely growing areas, are of the epith- 
elioid type. In some places the tumor cells seem to have escaped from the 
alveoli and grown unrestrictedly in large distended perivascular spaces. There 
are certain groupings which suggest that the tumor arose from the adrenal. 
The testis on that side is missing. Dissection was not made because the 
tumor was left in place and the whole bird kept for a museum specimen. 
1961 1/2. White Footed Mouse; Spindle Cell Sarcoma. 
This tumor apparently arose from the soft tissue of the upper hind leg on 
the right side. It presents a tumor about 2.5x2.5 centimetres of yellow white 
homogeneous appearance. The capsule is delicate but distinct. Micro- 
scopically it is an ordinary spindle cell sarcoma. Several areas have under- 
gone a necrotic change. Two irregular multinucleated cells were encountered. 
199S. Six Banded Armadillo. Fibroma Uteri. Acute Exudative Endo- 
metritis. 
The uterus is enlarged so that it measures 90 millimetres from the external 
OS to the fundus. The tubes and ovaries are apparently normal. There is 
considerable grumous blood around and outside the cervix. The cervix is 
pale and opaque in its lower half, while the upper half is slightly congested 
and the mucosa decidedly rugous. The uterus itself shows an attenuated 
muscular wall with a thickened irregular mucosa, which is the seat of pseudo- 
membraneous tabs of a dull red color. It is also mottled with yellow in some 
places. Grumous blood is present in this cavity. The size of the uterus is 
•due to a large fibroma attached to the left lateral wall near the cornu. The 
mucous membrane covering this mass is irregularly disturbed, the tumor 
being bare in some places. Here and there the mucosa shows the same de- 
generating and hypertrophic character as seen on the uterine wall. The 
tumor is attached to the wall by a narrow peduncle. 
The following cases seem worthy of special mention: — 
1907 . Nine Banded Armadillo. Rupture of ulcer in colon and hernia of in- 
testines. 
The following unique pathological finding was encountered in the above 
animal, supposedly dying from prolapsus recti. The only clinical observa- 
tions were hemorrhage from the intestines. "There is a large- amount of 
intestine protruding from the anus, which is covered with clotted blood. It 
measures 4 feet 4 inches. The length of the whole intestine from the pylorus 
to the anus is IGjft. The protruding portion is not gangrenous, and the 
animal probably bled to death. There is no indication of obstruction or 
inflammation, except as appeared later. The animal seems not to have been 
constipated." "There is a rupture of the anterior surface on the rectal wall 
about 8 centimetres from the opening, and the intestines are passing out of 
this perforation; No constriction at this point. The edges of the rupture 
are smooth and only at this point is there any indication of existing disease. 
This point shows a narrow zone of diffuse congestion with a slight thickening 
of the mucosa as if there had been an ulceration. In the neighborhood of 
the ulcer, there are small elevations of the mucosa ranging from 1 to 3 milli- 
metres, the larger ones of which show a pale gray center against the light 
yellow of the surrounding mucosa. This appeared to be small mucous cysts. 
The mucous membrane is soft, smooth, pale yellow and opaque." 
191,8. Common Raccoon, Poliomyelitis. 
This animal was observed in the Labaratory to have complete paralysis 
of the anterior and partial paralysis of the posterior extremities. This latter 
was almost complete in muscles controlling the feet, while the thigh and hip 
muscles showed some irregular incordinate movements. Respiration shallow
