 the body curved in such a manner as to bring the sexual or- 

 ifice opposite that of the pouch, the mouth of the pouch was 

 open or drawn down by contraction of the muscles so as to 

 receive the young when delivered. The young were seven 

 in number. The time occupied in delivery \vas about four 

 hours. The parent remained in the same position about 

 thirty-six hours and refused all sustenance. 



Immediately after the transfer of the young to the pouch 

 I removed one, by detaching it from the teat, in order to as- 

 certain if the movement of the foetus was instinctive. I found 

 that it was at least partly voluntary, as it made an effort to 

 regain its place in the pouch, and the same movement was 

 made by the parent, as at first, to receive it. I did not no- 

 tice any use of the limbs or lips of the parent during the 

 transfer of tke young.
