THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 259 
It also pecks at its own /foot and the nai of one’s 
hand. 
Chick C, hatched only a little while since, seems 
feeble, creeps rather than stands, and is soon tire 
out. 
All those tested do, without doubt, hear as well as see. 
They easily follow the hand by the eyes at a distance 
of 6 inches. 
Can get the winking reflexes only when the eyes are 
all but touched. 
A dark-eoloured box, a piece of cotton, and the hand 
are brought near the chicks in succession. The hand 
alone is followed, showing that it is the warmth that 
attracts. 
Solutions of salt and sugar, applied to the tongue, 
produce no decisive signs of the possession of taste. 
Two pigeons—the one a White Pouter, the other a 
Black Owl—were brought near, to test whether the 
chicks would show any instinctive fear. They mani- 
fested none whatever; on the contrary, they would 
nestle under them. 
The birds are tested again about twenty-two hours 
later. 
Previous to the first testing, they had not been from 
under the hen, and since then they have been under 
her and nowhere else. 
The three chicks now peck well at all that is put 
before them, as oatmeal grains, canary seed, etc. They 
peck readily, and touch the objects successfully. The 
hardest objects are not always taken up at once, how- 
ever. 
Some scales of dried lime-wash from the wall are 
placed before the chicks. In one case a chick pecks at 
a scale several times, then gets it into the mouth, but 
only to eect it.
