So early as the 3rd day the young cat gives evidence of the possession 
of genuine smell, as shown in its behaviour towards a dog placed near it. 
At the same time, the sense of smell is very feeble. Upon the whole, it 
would seem that taste and smell are both present rather sooner in the 
cat than in the dog, and in both the beginning is feeble, but they go 
on to fairly rapid development. However, I have not changed my 
opinion as expressed in my first paper on the dog,’ that the dog, and I 
will now add the cat, find the nipple of the mother by touch rather than 
by smell, and that they are drawn towards the belly of the mother by the 
warmth of the part. 
In both the dog and the cat there is a long latent period in the case 
of reflex movements from a pinch, etc., as compared with such an animal 
as the rabbit, though there can be no doubt that the tactile sensibility, 
the capability of feeling pain, and the temperature sense, as well as feeble 
motor power hardly worthy the designation (voluntary), exist in the dog 
and the cat at birth. 
I am not prepared either to affirm or deny that taste and smell are 
present at birth, but if they do exist, I am quite sure they are of the 
feeblest, of very little use to the animal, and play but a very subordinate 
part in its life during the blind period. 
The kitten is at first, if not always, more sensitive to a touch, has 
finer tactile sensibility about the mouth than the puppy. 
There are the same individual differences as to the exact date of the 
opening of the eyes, the eruption of the teeth, etc.,in the kitten as in the 
PE. 
The dog and the cat resemble each other in the slowness with which 
they acquire power over the hind limbs. 
Neither the puppy nor the kitten have any appreciable voluntary con- 
trol over the tail during the blind period; but the dog finally uses the 
tail much more than the cat in the expression of his emotions. What the 
dog does with his tail the cat often expresses by purring, which, as I 
have shown in the paper on the cat,’ is developed somewhat late—much 
later than the friendly wagging of the tail in the dog ; and as will be seen 
by a comparison of the notes (diaries) on the dog and on the cat, while 
there are definite stages in tail carriage for each, these are different alto- 
gether for the two animals, and herein we notice a far greater difference 
than in locomotor activity. The tail movements and carriage are defi- 
nitely related to the character of the animals, and to those that watch 
them closely, express distinct and varying phases of emotion, etc. 
The antipathy of the cat to the dog, while related to a psychic state 
based on self-preservation from intruders, is peculiarly marked towards 
the dog, though whether more so than towards any other similar animal,
