31st day.—ls out of its box—eries—is put into pan—after some delay 
urinates, 
Plays with carpet, a piece of coal, the edge of box, ete., its hack being 
arched, tail up, ete. 
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. 
Inthe evening it is found behind the barricade of the book-shelf sleep- 
ing 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 
erying 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 + to # 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. 
Physical. Its eyes are changing colour, being a sort of blue-gray. 
Paws no longer splayed. Its fur is darker in colour. It is rather a light 
tabby. ore-legs not quite straight. Tail carried vertically a great deal. 
To-day spends much time sleeping behind the barricade. When taken out 
it goes back persistently. 
Still sucks the mother, using the fore-paws vigorously in pressing on 
the mammary glands. 
It may be said to jump out of the box now rather than scramble out, 
i.e., lands on floor with a sort of leap; though it still scrambles in much 
as before. 
33rd day.—Found behind the barricade this morning before daylight. 
when trying to prevent its advance in a certain direction the kitten 
evades me by running under a rocking chair where it is partly hidden. 
See it trying to catch a fly in the pan to-day. 
When put in the pan now it nearly always paws the sand whether 
there is anything further or not. 
Mother and kitten play together to-day for the first time.
