THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 177 



It seems to require a good sharp pinch to cause 

 withdrawal of a part in a way to indicate pain, and the 

 latent period is notably long. 



6th day. Evidence that iodoform is perceived at a 

 J inch, blistering fluid at a inch, carbolic acid at 

 1 inch, and aloes at 2 inches. 



The kitten manifests a desire to escape from salt and 

 aloes but not from sugar. 



Moves better ; makes an attempt to crawl out of a 

 small basket which is lying half tilted over. 



The same sort of a pinch as before causes more 

 decided movement with a shorter latent period. 



The kitten shows no less uneasiness, but rather more, 

 when brought near the edge of the table. 



At a distance of 4 inches from the beagle dog the 

 kitten opens its mouth and spits. When the hands are 

 rubbed on the beagle, and brought near the nose of the 

 kitten, the same thing happens, but the hands must be 

 brought within 1 inch of the nose ; and the animal 

 seems to mind it less and less, though this is not so 

 manifest when brought near the dog. It still turns 

 away from the belly of the dog when laid against it. 



8th day. Eyes begin to open in two of the three 

 kittens. 



When I make a loud hissing noise the kitten with 

 the open eyes opens its mouth and hisses, and, when 

 the loudness of the noise is suddenly increased, its jaws 

 snap together audibly. 



The use of the dog-whistle is followed by uneasy but 

 not sudden movements of all three kittens. No sudden 

 movements of the ears in reaction to sound at present, 

 though they evidently hear. 



9th day. The eyes of one of the kittens still not 

 open. 



Two of the kittens tested seem to smell equally well 

 iodoform at f inch, carbolic acid at 1 inch, blistering
