THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 177 
It seems to require a good sharp pinch to cause 
withdrawal of a part in a way to indicate pain, and the 
latent period is notably long. 
6th day.—Evidence that iodoform is perceived at a 
3 inch, blistering fluid at a $ inch, carbolic acid at 
1 inch, and aloes at 2 inches. 
The kitten manifests a desire to escape from salt and 
aloes but not from sugar. 
Moves better; makes an attempt to crawl out of a 
small basket which is lying half tilted over. 
The same sort of a pinch as before causes more 
decided movement with a shorter /atent period. 
The kitten shows no less uneasiness, but rather more, 
when brought near the edge of the table. 
At a distance of 4 inches from the beagle dog the 
kitten opens its mouth and spits. When the hands are 
rubbed on the beagle, and brought near the nose of the 
kitten, the same thing happens, but the hands must be 
brought within 1 inch of the nose; and the animal 
seems to mind it less and less, though this is not so 
manifest when brought near the dog. It still turns 
away from the belly of the dog when laid against it. 
8th day.—EHyes begin to open in two of the three 
kittens. 
When I make a loud hissing noise the kitten with 
the open eyes opens its mouth and hisses, and, when 
the loudness of the noise is suddenly increased, its jaws 
snap together audibly. 
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. 
9th 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
