142 ANIMAL INTELLIGENCE 
quietly in the sawdust arose, and looked towards the 
source of the sound. 
54th day.—The same sort of pawing, and at the same 
places as before. 
It is scarcely possible to go into the kennel anywhere 
now when they are awake without some of them 
detecting my presence by ear, eye, or smell, or by all 
three, as is now evidently often the case. 
55th day—Warm. Much barking and restlessness. 
They have for some two or three weeks had the range 
of two compartments of the kennel, but they would 
evidently like the range of the whole yard as well as 
the outside run; and if this were once permitted, 
experience with other puppies has taught me, they 
might be unwilling to stay in the kennel at all during 
the day, which condition of things would not in several 
respects be desirable. 
The dog trodden upon still shows that he remembers, 
but will now turn to the lip-call. 
56th day.—Eighth week. Though the litter remains 
an even one, changes characteristic of growth and 
development are evident. 
The bitch puppy shows very pronounced changes in 
colour of coat, expression of face, temperament, etc., 
and has the most marked individuality of any of them 
at present. She seems still precocious. 
57th day.—They are so active it is difficult to move 
around among them. 
It is noteworthy that they use the kennel compart- 
ment they occupied originally as a retiring place to 
answer to nature’s calls, while they play, rest, and sleep 
chiefly in the additional compartment last given them. 
Perhaps this is to be accounted for in part by the 
fact that, from the latter, there is a door opening out- 
ward, and another of wire-netting, through which they 
can look out and catch an occasional breeze.
