THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 189 



deny. Growing well. Weighs 1J Ibs. Is given 

 milk, then placed in pan and uses it. 



To-day when called " Puss ! puss ! " as it lies behind 

 the barricade, it conies out. 



Now manifests pleasure in being stroked. 



Its vision is now so keen it can rapidly follow 

 movements of the fingers, etc. 



It scrambles into the book- shelf by a new way and at 

 a much greater height. 



Is seen to catch at its own tail for the first time. 



Two Skye terrier puppies are brought near the kitten. 

 It makes a great fuss, showing all the signs of anger, 

 etc. 



Some cooked fish (of which cats are notoriously fond) 

 was placed before the kitten. It licked this but did not 

 eat any, though there seemed to be a certain amount of 

 surprise and excitement. 



36th day. The day is dull, and the kitten, lies in its 

 box a great deal in the forenoon, though later it rouses 

 itself and plays with its mother. 



I try for some reason to intercept the kitten when it 

 makes a long run to escape. 



To-day, for the first time, it crosses the threshold of the 

 room door, but was scared back. 



For the first time, too, it sinks its claws into an upright 

 object, as an old cat often does. 



Some raw meat is placed before its nose. It sniffs at 

 this, but makes no attempt to eat it. 



It begins to understand better the meaning of the 

 call "Puss! puss!" 



Its manner of play now much more active and com- 

 plicated. 



Is noticed stalking on two occasions to-day once 

 towards the mother's moving tail. 



37th day. This morning early the kitten enters the 

 pan, of its own accord, and functions.
