affected, and that the colon is more often diseased than 
in other mammalian orders, and is exceeded only by the 
gallinaceous birds. 
The Lemures, of which we have eighty-six autop- 
sies, do not differ much in anatomy from the Primates, 
however greatly they disagree in habits and outward 
appearance ; their diet is the same. Clinically the sloth- 
ful behavior of a normal lemur probably obscures 
symptoms and signs of illness, for our antemortem notes 
with the exception of a few observations of loose stools, 
fail to offer a lead as to diagnosis. This order has a large 
incidence (twenty-three cases) of gastroenteric condi- 
tions as shown in Table 11, but some explanation of the 
figures is deserved. In the first place, only one case of 
acute gastritis occurred, and this was apparently a part 
of a general infection, and if induced at all by food this 
was only secondary. Indeed as one reviews the records 
it does not seem that the lemurs are easily disturbed in 
their gastric digestion. Acute and subacute inflamma- 
tions from bacterial action seem definitely more promi- 
nent since they take the catarrhal, follicular and deep 
submucous form and are frequently associated with gen- 
eralized infectious processes. One amoebic case was 
observed and there was another in which a heavy cestode 
and nematode infestation seemed to have paved the way 
for bacteria. 
Carnivora. 
The food of this order is received into the fundal 
part of the stomach, the distensible but normally capa- 
cious left and superior two-thirds of the organ. The 
general shape of the viscus, that of a gourd, permits a 
fairly sharp separation of the fundal and pyloric sections, 
so definite indeed that the pathology of the two parts was 
studied. The intestines vary in length, but in the 
land carnivores are relatively short, narrow in lumen 
and rich in waU. A cecum, or at least a blind end of the
