fat. 127 grams were removed from other portions of the body in 
pieces of varying size. The whole amounted to 027 grams or 
more than one-sixth of the weight of the body. In view of the 
presence of fat in thin sheets between the muscles and over them, 
a conservative estimate would be that the amount of fat stored 
for use during the winter’s cessation from activities was more 
than cne-fourth of the total weight of the animal. 
In our common hog, which dees not hibernate, the thickest 
layer of fat is likely to be over the shoulders—the most exposed 
portion. 
It would be interesting to learn the conditions in other ani¬ 
mals, such as the bear, which hibernate. In this case it is plain 
that as the raccoon curls up in the hollow tree with his nose 
between his hind legs and his tail over his head and shoulders, the 
rump and back make the less protected part of the circle. Hence 
the location of the heavy fat blanket in that region.
