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. Iam 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. 
Ath day.— Eating green food. 
7th day.—Hating 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 squeaks a good deal. 
They eat well, but follow up the mother at times 
to suck. 
10th day.—They now eat as fast and well as 
mature animals, and in nearly all essential respects 
resemble them,
