[MILLS] PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 197 
Soon it leaves the box again and goes to a part of the room where 
there are some book shelves, the lower ones of which are not completely 
filled with books, but hold other things. 
The mother follows it. The kitten is put back into its box, 
First noticed to-day what seemed to be purely voluntary movements 
of the ears. 
Continues to notice shadows, and to-night tries to put its paw on them. 
Still takes no notice of meat. 
Licks hind foot, and while doing so spreads its toes apart as an old 
cat may be seen to do under similar circumstances. 
27th day.—On getting out of box starts on a little run for the book 
shelves. 
It was taken from among the objects on the shelf, turned towards 
the box and given a few taps. It ran on to the box and got into it.

the milk into the nose, which causes sneezing. 
Plays with a small piece of coal found in her box. 
On suddenly throwing aside a curtain that covers the book shelves, 
the kitten is found there and hisses. 
I place her in a rocking chair over 18 inches from the floor, but she 
manages to scramble down without injury to herself. 
About 5 p.m. the entrance to the book shelf was barred up. The 
kitten first tries every part of the barricade, then pushes in the curtain 
—cries with vexation—climbs upon a box near—leaps from this on the
