THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 235 



From the first the respiratory movements of the 

 nostrils, so characteristic of rabbits, are shown. 



They can also wipe the face with the fore-paws a 

 very characteristic act of the rabbit, or perhaps one 

 should say, of the rodent. 



The manner in which they push under one another 

 and huddle together, shows how they, like other young 

 animals, are rendered uneasy by cold and quieted by 

 warmth. 



They will not crawl off a surrace, but when they near 

 the edge turn back. 



3rd day. There is a very noticeable increase in size. 



Their movements are more pronounced. 



The first scratching of a surface (in this case, my hand, 

 as one lies upon it) noticed. 



This is a highly characteristic act of mature rabbits. 



When they are put back into the straw near the nest 

 proper, they push through and get to the other young xp 

 ones in the nest, evidently attracted by the warmth. ^ 



Cannot induce them to suck my finger, as puppies 

 will do readily, though a little more inclined to suck the 

 lips or the end of the tongue. 



4:th day. Hair is now growing over the whole sur-/ 

 face of the body. 



7th day. Irritating liquids used before now produce 

 more decided results, and at greater distance. 



The evidence that milk is smelt, though doubtful in 

 one case, seems clear in another. 



Testing as regards taste I have found very difficult 

 in the rabbit, as the tendency to withdraw the mouth 

 suddenly is very strong. 



There seems to be no doubt, however, that a solution 

 of aloes produced disgust. 



There is a great advance in movements. They are 

 very quick and irregular, and may be to one side or the 

 other as likely as forward or backward. ^Reference
