a supply of air. Under this i^lass was placed a oood supply of 

 waste cotton. Soon after it was fairh- established in its new and 

 V- more commodious quarters, it beo-an to clean every part of its body 



in the most thorouo^h manner, washlnLj; itself ver)" much in the 

 same manner as a cat washes. On comim^' to the tail it passed 

 that long- member, for its wliole length, through the mouth from 

 side to side, beginning near the ])ody antl ending at the tip. At 

 night as soon as the lights were put out the mouse began gnawing 

 the paper, and during the night it gnawed all the newspaper it 

 could reach, and made the fragments and the cotton into a large 

 nest perhaps five or six inches in diameter, and established itself 

 in the centre. Here it spent the succeeding day. The next night 

 it was supplied with more paper, and it gnawed all it could reach, 

 and thus spent a large part of the night in work. I could hear the 

 work going on when I was awake. In the morning it appeared to 

 be reposing on the top of its nest ; but after watching it for some 

 time, and seeing no motion, I lifted up the glass and took the 

 mouse in my hand. It showed no signs of life. I now felt that 

 perhaps nn- pet was indeed realh' dead ; but reniemlocring what I 

 had previously seen, I resolved to try to restore it again to activity. 

 By holding it in m)- hand and thus warming it, th(; mousc^ soon 

 began to show signs of life, and although it was nearU' the whole 

 day in coming back to actix'ity, at last it was as lively as ever, and 

 afterwartl, on being set free in the room, it moved about so swiftly 

 by means of its long leaps, that it recpiired two of us a long time 

 to capture it uninjured. 



" On the evenino- of Fcbruarv 6th I reached my home in 

 Williamstown, and on my arrival the mouse was in good condition. 

 But the next morning it was again apparently dead ; in the course 

 of the day, however, being placed where it was warm, it gradually 

 came back to activity as before."

 Mouse remains torpid till the hist of May or first of June, are
