204 ROYAL SOCIETY OF CANADA 
When on the table a spool falls to the floor. In an instant the kitten 
leaps from the table to my wife’s lap, and thence to the floor. In its 
play runs behind the book shelf and rushes out at its mother from behind 
the curtain again and again. 
49th day.—Catches flies on the window —takes no notice of dead flies, 
When engaged in this sport it upsets a vessel containing a little milk, 
and is so startled by this that it rushes down at once with a peculiar ex- 
pression on its face. 

50th day.—When we are at dinner to-day, the kitten runs into the 
dining-room on the flat below its home. 
Since this long wandering from home it is difficult to keep it in the 
study, as it wishes to be here, there and everywhere, maintaining cease- 
less activity when not asleep. 
Jumps from the table to the floor by one clear leap. 
51st day.—The kitten climbs from my chair up my back, and rests 
on my shoulder. 
As its mother walks up-stairs, the kitten crouches back from the top 
as if to spring on her by surprise. 
52nd day.—Again climbs up my back and remains there while I walk 
downstairs. 
On coming home late I go into the dining-room, into which the 
kitten also shortly walks. 
53rd day.—I can notice a change in the shape of the kitten’s head. 
It is more elongated, ete. 
Its eyes are also changing colour—getting lighter. 
54th day.—Is very playful all day. 
At night, late, when I go into the dining-room, the kitten follows, 
and when there climbs half way up a wire-netting door separating the 
kitchen from the dining-room. 
On stroking the kitten to-day it is noticed to purr for the first time. 
55th day.—On stroking the kitten it purrs. Soon after it sits on the 
table and purrs of its own accord still louder. 
56th day.—Manifests an unusual desire to sit in my lap and on the 
cushion of the chair between my legs. 
57th day.—The kitten eyes very closely, from the top of a rocking 
chair, a canary bird in a cage at a height of two to three feet, and at 
about four feet distant. 
It also crouches when it sees flies moving on the floor, etc. 
A small dachshund dog is brought into the study to-day. The kitten 
puts up its back, growls, ete. The little dog and the kitten are then 
taken on my wife’s lap. The kitten holds off, but looks interested, and 
finally approaches and smells at the dog. 
Spontaneous purring occurs this evening. 
The kitten “ washes its face,” at first one paw then the other, in an 
elaborate way not seen before.
