248 ANIMAL INTELLIGENCE 
3rd day.—lt does not wink when its eyes are touched, 
and it is doubtful if it sees. 
On touching the bird it moves more than it did 
yesterday, and now and then it opens its mouth a 
little. 
On removing this 1? inch from its mate nestling, it 
shifts back again, guided chiefly by the warmth from 
its fellow, I take it. 
It is placed on a perch about 14 inch wide. It does 
not fall off, but clings to it. When my hand is held 
within 1 inch, and below it, the bird puts down its 
beak, touches my hand, and scrambles down into it. 
Every time I use the dog-whistle the bird moves its 
head, which is a proof of hearing, for care is taken to 
exclude the contact of the blast of air from the whistle. 
Ath day.—It will, when placed on the perch, as 
before, put its head down a great distance, but does 
not move from its secure position; but it does creep 
off into my hand under the same circumstances as 
yesterday. 
5th day.—lIt spreads out its wings when disturbed in 
any way, or when in danger of falling off the roost. 
There is no evidence that the bird can distinguish 
objects by the eyes. 
The winking reflex seems to be wholly wanting. 
A solution of quinine and one of sugar are used to 
test taste, but with no clear results. When blown on, 
etc., it utters the sownds peculiar to young pigeons. 
6th day.—The bird can see at a distance of 1 foot 
to-day, as evidenced by its movements when the hand 
is passed before it. 
Holds its eyes open a good part of the time now. 
Under the application to the tongue of solutions of 
sugar and of salt, there is some shaking of the head, 
which is possibly evidence of taste. 
7th day.—Clear evidence of vision at 2 feet.
