THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 237 
Very decided advance made in the position of the ears ; 
they are more upright and are moved more readily. 
Can get no evidence of vision. 
Can get no reflex from the eyes till the cornea is 
touched, and not very good then. 
About the heaving there can be no doubt whatever. 
14th day.—The ear carriage is still better. Hye re- 
flexes feebly present. 
They are found out of the nest, and go to the mother 
to suck when distant from her 2 or 3 inches. 
15th day.—Since they strike against the side of the 
nest (board) I am satisfied there is no distinct vision. 
They are able to reach the mother when 3 or 4 inches 
distant. 
They seem to smel/ fresh, green food placed in the 
larger box, with which their nest communicates. 
They do not seem to start quite so much when 
touched as they did. 
The rapidity of general growth, and especially of the 
hair, is impressive. 
There is an obvious advance in smell and taste. 
While not certain, I have a suspicion that they begin 
to distinguish objects. They possibly take notice of 
shadows. 
The first attempt at eating made to-day by nibbling 
at grass put before them. 
They now begin to dope in the manner peculiar to 
rabbits, 
They also begin to get up on the hind legs. 
They will by no means creep off any surface on which 
they are placed. 
They now hear a soft whistle at from 4 to 6 feet, as 
is evidenced by starting movements and ear movements 
(reflex). 
The ears, however, do not move backward or forward 
but laterally.
