THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 119 



5th day. When pinched, they gave evidence si feel- 

 ing by a cry and movement, though the latter is not very 

 marked. When the hand is laid over them in a caress- 

 ing way just afterwards they are at once quieted. I 

 regret that this experiment was not made earlier. 



6th day Several attempts are made to ascertain if 

 they smell, but with uncertain results. Warm milk 

 and meat were held near their noses. I think there was 

 some sniffing as a result, but cannot be certain. 



7th day. Growing well. Two specimens (females) 

 weigh 2 Ibs. 7 oz. and 2 Ibs. 10 oz. respectively. Tested 

 taste by the use of milk and of aloes. A finger dipped 

 in milk is long sucked. When aloes, in solution, is 

 placed on the finger, the latter is not long sucked, and 

 the facial movements indicate disgust, quite the reverse 

 in the case of anything sweet. I endeavoured to learn 

 whether they knew if the dam were near them by smell, 

 but could not establish it. Up to this date, and long 

 after, no evidence of hearing to be elicited. 



9th day. When the dam is out of the pen, as she now 

 often is, the puppies suck frequently at different parts 

 of the bodies of each other. They will suck vigorously 

 and for some time at my finger. 



It is easy to notice now great progress in power of 

 movement, especially as regards the forelimb, mouth 

 parts, and head or neck. No movement of the tail at 

 all yet nor for some time. 



Wth day. I again attempted to determine whether 

 they could smell, in the same manner as before, but 

 with no definite results, though strongly inclined to 

 believe that they could to some extent. 



When the dam, after an absence, steps into the pen, 

 two or three may happen to get between her legs after 

 she lies down. Presently these and others commence 

 to move in a lively way in all directions, and before long 

 manage to reach the teats.
