234 ROYAL SOCIETY OF CANADA 
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 lope 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 four to six feet, as is evidenced 
by starting movements and ear movements (reflex). 
The ears, however, do not move backward or forward, but laterally. 
These organs are now thinner, held more erect and better unfolded, 
so to speak. 
16th day.—I think they begin to distinguish objects by sight, though 
it is difficult to demonstrate this. 
It is impossible to produce the winking reflex till the eyes are actu- 
ally touched. 
17th day.—It is difficult now to say whether they approach objects 
through sight or smell. 
18th day.—When I sneezed close to their box to-day they all huddled 
together in a startled way in a corner of their nest, in a manner very 
characteristic of older rabbits when alarmed. 
By the manner in which they leave and enter their nest I conclude 
that they retain the memory of the relations of objects apart from visual 
and olfactory sensations. 
The mother is now weaning her offspring. 
One is seen circling around in the box as if attempting to find the 
mother by feeling, making it doubtful if distinct vision is even yet possible 
to them. 
To-day they eat clover. 
20th day. —They not only eat green food, but gnaw at a crust of stale 
bread. 
They jump about in the box as if playing. 
They seem to follow by smell a green stalk I hold in my hand. 
One is so startled by my sneezing that it jumped off the top of a 
barrel on which I had placed it. 
The ears are now relatively longer and thinner and are better held. 
21st day.—They detect objects (food) by smell at an increased distance. 
They are leaping about a good deal, apparently from excess of vitality. 
22nd day.—They follow my finger as I move it, so that I think there 
is now no doubt that this is done by sight. 
They eat stale bread quite well. 
24th day.—The young rabbits are removed to a large cage. They 
now show fear when a sudden motion is made, showing that they see well
