(11 by 8J inches) at 4 feet. Is able to locate whether 

 a light " Hist ! " is uttered on the right or left. 



Licks its paws occasionally. 



Sleeps a great deal. 



18th day. Seems to be following with its eyes the 

 movements of a fly at 4 to 6 inches. 



Turns to bite at objects and puts paws together a 

 sort of feeble attempt at play. 



Climbs up side of box to the top and then cries, as 

 though desiring to get out. 



On calling " Puss ! puss ! " softly, at about 3 feet, 

 the kitten turns toward the sound and moves the ear 

 nearest to it. 



A piece of cooked meat is held near, but no special 

 effect is noticed. 



At 5.15 P.M. the kitten is seen to be plainly follow- 

 ing flies with the eyes at 18 inches, and slightly raises 

 paw in an attempt to catch them. 



Licks its own paw, and then licks mother's leg which 

 is close to it. 



In the evening it gets lively and makes attempts at 

 play, and crawls over the mother, biting at her and 

 itself (play). 



The nose is now getting pigmented. 



19th day. At 11 P.M. to-day follows finger by 

 lamplight at 4 to 5 feet, climbs upon mother, and sleeps 

 there. 



20th day. When "Puss! puss!" is called to-day, 

 the kitten hisses softly (surprise). 



There is now nearly always a distinct movement of 

 the ear towards the direction of sounds. 



Is taken from the box to-day, and, when free, walks 

 towards it. 



21st day. Grows well, still sleeps much, and is very 

 quiet. 



After being out of box a short time it returns to it
