held on with considerable strength, but being placed with the 

 mother soon found its proper hold, which they all seemed to 

 maintain until the eyes were open or nearly so; then I noticed 

 that when the mother desired to move to another part of the 

 cage — she is very neat — she would turn round and round and 

 seem to twist them loose in a pile, where they would lie quietly 

 until they felt her return, then tliey would at once attach to the

"I found them about May loth, and they may have been 

 about a week old. About a week ago (about May 20th), their 

 eyes began to open, and now they are wide open. They eat 

 with the mother, who' takes almost anything from roast beef or

 then the young attach to the mammae and all sleep. 



"They seem tO' be quite' nocturnal, decidedly more active at 

 night, and are out in the day only to eat a little. I should think 

 the young are now about four weeks old. They are nearly half
