THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 187 
It makes many attempts to get into the book-shelf 
and at last succeeds. 
For its play, even the leg of the table suffices. It 
darts back as if it was afraid of it, ete. 
31st day.—Is out of its box; cries; is put into pan; 
after some delay urinates. 
Plays with carpet, a piece of coal, the edge of box, 
etc., its back being arched, tail up, etc. 
Notice movements of tongue, jaws, etc., when asleep, 
as if sucking or lapping milk. 
This morning the kitten stretches, like an old cat, four 
or five times when it gets out of its box (first time seen). 
A string, curled up at end, is dangled before it in the 
box. The kitten starts back and hisses. 
In the evening it is found behind the barricade of 
the book-shelf sleeping on some books. It is taken 
out, but works its way back again. It finds getting 
out difficult, but perseveres. 
To-day plays with a ball and a spool. 
This evening laps milk without any trouble for the 
first time. 
32nd day.—Kitten seems uneasy; is placed in the 
sand pan; after crying and pawing it passes urine. 
Then slips out and stretches itself. 
Still some trouble with nose when lapping milk. 
Enters the pan of its own accord. No results. 
It tries the book-shelf barricade, but not succeeding 
gives up, and sits in its box near by,and grooms itself well. 
Later, it makes a more determined attempt on the 
barricade, and with success. It has difficulty in getting 
out, but soon goes in again and remains from half to 
three-quarters of an hour. 
Enters pan; cries; urinates; much licking of the 
paws after it leaves the pan. 
On moving one of my fingers before it, the kitten 
boxes with it.
