[MILs] PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 193 
The’ use of the: dog whistle is followed by uneasy but not sudden 
movements of all three kittens. No sudden movements of the ears in 
reaction to sound at present, though they evidently hear, 
Ith day.—The eyes of one of the kittens still not open. 
Two of the kittens tested seem to smell equally well: iodoform at # 
inch, carbolic acid at 1 inch, blistering fluid at 1Sinch. Dislike manifested 
by turning the head away and putting up the paw to nose as if to push 
away something. The mouth is also opened. 
Kitten licks with evident pleasure at some candy. It licks at salt 
also, but soon shows disgust. Aloes gave a doubtful reaction. 
When the foot is pinched the kitten now cries out sharply. 
There is a noticeable improvement in locomotor action. 
It is impossible for me to convince myself that any of the kittens see. 
There is a strong tendency to keep the eyes closed a good part of the time. 
The winking reflex is not produced by moving objects before the eyes, 
but follows only when the hairs of the lids are reached or the lids them- 
selves, or some other part of the face or the head is touched. 
On the other hand, both a sharp sound from the whistle and a loud 
sound imitative of a bark, causes the kittens to start, but a hissing sound 
affects them most, and at a distance of 3 to + feet, will cause them to open 
the mouth and hiss. 
The ears now move reflexly to sound, but turn towards the point 
from which sound comes, or, at all events, towards the side rather than 
straight back, as in dogs, or as in rabbits, etc. 
Quivering of the ears is noticed, but the cause is not obvious. They 
turn to the quarter from which sound comes. 
10th day.—No clear evidence of power to distinguish objects by the 
eyes as yet. The ears are noticed to move without any apparent stimulus. 
The quivering still continues. With each mew the kitten shuts its eyes. 
A sharp whistle causes the animal to start, but the ears move but 
little. The kittens crawl rather than walk yet, though the pace is 
increased. There is some amount of fail movement. 
11th day.—Two of the kittens give evidence of seeing, though one 
rather better than the other. The eyes are now well open. Seem to see 
at 10 to 12 inches distance, though the evidence of this is not conclusive. 
Winking reflex on movement of the fingers before the eye at } inch or a 
little more. 
They can now cry with a relatively loud voice. 
On testing taste with aloes disgust is very plainly shown. 
Ears seem to be moved voluntarily. The quivering continues. 
12th day.—When cooked beefsteak is held within one inch of the nose 
it is smelled, as evidenced by sniffing, ete. 
When held near the nose of another it hisses. Neither shows any
