In another case it is not distinctly taken into the mouth and expelled, 
but is simply picked up and at once dropped. 7 
Water is presented to the chicks. They peck at some drops on the 
side of the tin containing the water. 
; They accidentally get the beak into the water, when drinking fol- 
lows. 
They do not spontaneously put in the beak and drink either before 
this accidental result or after, and in this matter they all three behave 
alike. 
They are seen to scratch the head with a foot. 
At this age another lot of six, which are with a different mother, de 
drink on invitation (clucking) of the mother. 
They also eat rather better on her invitation than without it. 
They run to the mother from a distance of four feet. 
Five hours later —The mother hen drinks, whereupon two of the 
chicks run rapidly from a distance of six inches and drink. . 
One of them wipes its beak on the ground. 
The hen is later in a box, and cannot be seen by the chicks, yet they 
move towards her, 7. ¢., in the direction of the sound she makes. 
3rd day, 2 p.m.—They have been fed a couple of times before to-day. 
They are now given very small pieces of meat, with which they run 
off, peck it against the ground, and make off from each other as does a 
mature hen. Oneeven escapes through wire netting into the next “run.” 
They are now out of doors in suitable “ runs.” 
One is seen to swallow a piece too large with no more difficulty than 
a mature bird apparently. 
One of the chicks begins to eat lettuce on which the mother hen is 
feeding. 
A pigeon (the same one used before) is thrown into the run where 
the hen and chicks are. It flies about a little and then alights. The 
chicks did not show the least fear, etc., though the hen attacks the 
pigeon, uttering a faint sound (danger signal) peculiar to fowls when a 
bird, as a hawk, flies over them. 
9th day.—Feathers shooting out well. Ditferences in colour very 
marked. 
14th day.—Tried the black owl-pigeon as before. No special mani- 
festations on the part of the chicks, nor were there any when the other 
of the two pigeons before tried was suddenly thrown into the run and 
fluttered about. 
REMARKS ON THE DIARY OF THE CHICKS. 
Previous to writing the notes on the chicks that were the subject of 
the present paper, I had observed fowls, young and old, from boyhood.
