242 ANIMAL INTELLIGENCE 



A couple of them are put into a box 18 by 18 inches, 

 in which there is some salt, some brown sugar, some 

 " peppermint rock " candy, and some camphor. 



They licked at the salt once but did not repeat this, 

 but went again and again to the sugar or remained by 

 it. They did not remain near the other substances. 

 They were not kept long in this box. 



A leaf of lettuce was just after placed before them. 

 They seemed to like to be near it, and very soon 

 began to nibble at it. 



They wipe the face with the paws much like a 

 mature cavy. 



Of the three constituting the litter one was from the 

 first much larger. 



The larger one was observed to get from its nest to 

 the box, a distance of 2 inches, when not more than 

 three and a half hours old. 



2nd day. At 1.30 P.M. one of the cavies was put 

 into the box occupied by a rabbit. It did not approach 

 or attempt to suck it. I am satisfied it recognised the 

 creature as " strange." 



It eats sugar from my finger, and follows the finger 

 by sight I think. 



The eye must be almost touched before the winking 

 inflex is produced. 



3rd day. Nibbling at green food. 



4:th day. Eating green food. 



7th day. Eating food, oats, and stale bread, and they 

 seem, in most respects, to act like old cavies. 



8th day. One is taken to my laboratory for the pur- 

 pose of brain study. On the way it syueaks a good deal. 



They eat well, but follow up the mother at times 

 to suck. 



IQth day. They now eat as fast and well as 

 mature animals, and in nearly all essential respects 

 resemble them.
