[MILLS] PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 205 
58th day.—It is beginning to be difficult to keep the kitten out of 
the dining-room, and to-day it tries hard to get in by the wire-gauze 
door. 
99h day.—The kitten seems to be uneasy when quite alone. 
Came up-stairs to-day to use the pan. 
There is a fire in the grate in the study for the first time this 
autumn. The kitten touches the poker, which is hot. It hisses, etc. 
but soon after it touches it again and again, in its usual persistent way. 
GOth day.—After tea I lie down on a sofa in a room adjoining the 
dining-room, whereupon the kitten climbs upon the sofa and walks 
from my legs up to my chest, where it remains purring. 
Now generally comes when called “ puss,” ‘ puss.” 
Present physical condition : 
Colour not very greatly changed. Is still a light tabby. 
The shape of the head is now much more like its mother’s. 
The eyes seem to be getting lighter. 
Weight, 24 Ibs. 
Height, 7 inches. 
During the past two weeks it shows much waywardness. When an 
attempt is made to thwart the kitten in any way, it bites, scratches, ete., 
in a half earnest, half playful way. 
63rd day.—Slips by some mishap in part into a water pitcher, which 
is followed by hissing and a great fuss generally. 
65th day.—For the first time is allowed outside on the front steps. 
No longer remains as much in the study. 
67th day.—Kitten to-day micturates in the corner of the study, not- 
withstanding that it had been solicited to use the pan. Is punished with 
a small strap. 
70th day.—For the past two days the kitten is much inclined to re- 
peat the offence of the 67th day. 
Very active and very mischievous. 

Seems to take a delight in interfering with one’s reading, writing or 
whatever I may be engaged in. 
Late in the evening [ call “ puss,” puss,” but no puss comes. After 
looking here and there it is discovered beneath the table, beside the 
waste-paper basket, trying to hide from me. When I go to one side of 
the basket the kitten betakes itself to the other. 
77th day.—\s plainly growing fast, especially in height. 
The kitten up to the present has been out of doors in all about half 
a dozen times. On one occasion cried to get out. 
The kitten still cries when it feels any want or when it cannot 
accomplish its object, or is disappointed, e, g., it will cry if it goes to the 
window and cannot find flies to catch.
