240 ANIMAL INTELLIGENCE 
10th day.—Kyes not yet open. 
Green food held within 2 or 3 inches is sniffed 
at. 
Hair has now grown on the body to the length of a 
quarter of an inch. 
12th day.—Eyes of some of the litter now open, but 
not of all. 
The slightest touch with a leat of green food causes 
them to leap in the nest. 
They now move the ears and start when I produce a 
moderately loud noise with a dog-whistle. The ears 
are moved to the extent of one-quarter to one-half inch. 
14th day—They now move readily from the nest, 
which, as in the former case, is situated in one corner, 
and elevated a few inches, to some other part of the 
box and back. 
Suspect feeble vision, but cannot demonstrate it. 
They begin to nibble green food. 
15th day.—Their mode of progression is more like that 
of the mature rabbit, 2.c. loping rather than walking, in 
the ordinary sense of the word. 
17th day—They are seen not only to lick and scratch, 
but to dite. 
18th day.—Begin to poke into corners now when 
placed on the floor. 
19th day.—There is no doubt that they now see. 
20th day.—One now begins to show the dark markings 
on tail, ears, and nose, characteristic of the breed. 
They now scratch hard at the wood of their box at 
times. 
21st day.—They eat oats. 
25th day.—A fair pad of hair has developed on the 
foot. 
They are now put down with the members of the 
other litter, twenty-two days older, and act very much 
as they do.
