[mitts] PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 203 
Again visits the waste paper basket and plays with some crumpled 
papers in the bottom. 
Smells keenly at my fingers that had handled a recently killed mouses 
When the mouse is presented to it, the kitten smells it, licks it, and 
then bites it. When I attempt to draw the mouse away the kitten holds 
on with its teeth and claws, and growls slightly. 
Jumps down from a height of 14 feet to-day without any fall. 
43rd day.—Kitten sleeps much to-day. When awake wishes to be 
either in my wife’s lap or on the table. 
Offer it some meat. Smells and licks it, but makes no attempt to 
eat it. Licks its lips long after the meat is put to its mouth, as if to get 
rid of the last trace of the meat. When it is brought near it again 
makes off. 
Is very playful this evening. Interferes so much with the pen as 
one writes it is impossible to do so while it is near. 
44th day.—Plays vigorously, but not long, at one time. Sleeps a 
great deal. 
In the evening finds a new hiding place and fails to make any sign 
when called. 
Ts put in pan, but will not remain in. Micturates im à corner and is 
given a mild punishment, which is well borne. 
In the evening visits the pan, and after using it, takes great pains 
to paw up the sand into a heap. 
Catches flies. Plays with one of them after it is dead. 
Runs into the most distant room on the flat on which the study is, 2.e., 
it goes further from home, so to speak, than ever before. 
4oth day.—Races about much to-day, under chairs, out of the room, 
etc. 
Of its own accord visits the pan and defæcates twice, taking pains 
to cover up what is passed. 
46th day.—Eats for the first time to-day small piece of cooked meat 
and potato; licks the plate on which it is, and seems to like the food 
very much. 
Acts with a dead mouse as before. 
Plays with its mother so violently that the latter seizes it and holds 
it down. 
47th day.—A piece of catnip that affects mature cats so peculiarly, 
produces no such effects on the kitten, which seems rather to dislike the 
smell. 
48th day.—F ull of an apparently reckless activity. Climbs up and 
down chairs, ete., with great vim and rapidity, but never falls. When 
tired sleeps, and sleeps long. 
Meat is offered to-day. Smells at it but does not eat till a small piece 
is placed in its mouth, when it eats with apparent relish all placed before 
it.
