There were several nodules the size of hens' eggs scattered

White-footed Mouse (No. 4985). Carcinoma of lung. 
White-footed Mouse (No. 5028). Carcinoma of mam-

Arterial Disease. 
This year Dr. Corson-White has been particularly 
inquisitive in her search for the above conditions and as 
a result an unusual number (28) will be found listed 
in the systematic classificatory list at the beginning of 
this report. In 1914 only 6 were listed, in 1915, 7, in 1916, 
9, in 1917, 8, and in 1918, 12. Without going deeply 
into the matter, the occurrence of this disease with few 
exceptions in carnivorous animals (birds particularly) 
cannot fail to attract attention. Four aneurysms, 
5 cases of atheroma, and 19 of arteriosclerosis compose 
the 28 cases.
