THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 129 



I notice one sleeping and another licking its face 

 after feeding, using its paw wi% movements closely 

 akin to those of the fore-limb against the mammary 

 glands when sucking. 



I can observe a very considerable advance in the use 

 of the hind limbs in walking in four days. 



During the night one of the puppies had got out of 

 the pen and was making loud outcry and trying to get 

 back. 



24:th day. Special tests as to sucking finger gave the 

 following results : 



Some on one occasion suck the finger, others do not. 



Later, three were tried, one asleep or almost so, the 

 others not, but all sucked the finger tip. 



One lying sucks the finger, and puts up its fore feet 

 towards the hand, and spreads the claws, at the same 

 time moving the hind limbs somewhat. 



One, when standing and sucking at the finger, also 

 lifts its paw. 



25th day. A piece of meat held before the nose of a 

 sleeping puppy at a distance of 2J inches wakes it 

 (smell). When this piece of meat is rapidly moved 

 before the face at 3 inches, it is as rapidly followed 

 by movements of the head. Was this owing to smell, 

 or sight, or both ? 



When the meat is put into the mouth it is not 

 merely sucked, but an attempt is made to chew it. 



When the hands are clapped sharply once, starting 

 is produced, suggestive of more than a mere reflex 

 possibly real/right. When I whistle somewhat lightly 

 some of them lark. 



26th day. When I whistle at the distant end of the 

 pen they bark, some of them, but, employing the lip- 

 call, they move in that direction. 



Moving a small piece of rag before them as was 

 done with the meat yesterday, causes similar correspond-
