HIBERNATION AND ALLIED STATES IN ANIMALS 85 
sleep. Not only did he eat less frequently, as a matter 
of course, but the quantity taken at one time was less. 
Occasionally, when fully hibernating, he would awake to 
fall asleep again, merely after gathering the straw about 
him a little closer, and not eat at all. His cage always 
being supplied with food, there was no doubt about his 
ability to provide himself when so inclined. 
His excretions were also in proportion to the amount 
of food consumed, and especially to the depth of the 
sleep. The less he ate, and particularly the more pro- 
foundly he slept, the less were his evacuations when he 
awoke. He never befouled his bed, but always left it to 
void urine and feeces. 
During the period of mere drowsiness the animal 
would be awakened by a gentle rustling against its cage, 
and even when asleep, a noise, etc., would always arouse 
it, but when in a torpid condition it could not be thus 
aroused, but might be handled without being brought to 
the natural condition, though handling and much less 
disturbance always caused movement, a phenomenon to 
be discussed later. 
In the spring of 1891 my Woodchuck came out of his 
winter sleep in a very emaciated condition, and this, as 
usual, increasing after his awakening, he was in a doubt- 
ful state; but the case was soon decided against the 
animal in consequence of my servant having left him 
for some time fully exposed to the sun’s rays. An 
autopsy revealed the fact that the animal (a male) was 
the subject of tuberculosis of the lungs, though possibly 
but for this exposure he might have lasted another 
year. 
Through the kindness of Mr R. F. Rorke, an under- 
graduate in medicine of M‘Gill University, I became 
possessed of two specimens of the Marmot in the latter 
part of the summer of 1891. One of these was very 
large and in fine condition, and his escape soon after
