Solutions of salt and of sugar, also cow’s milk are presented at 
different times. Certain conclusions cannot be drawn, The brush on 
which the solution of sugar is presented is sucked vigorously however. 
The puppies will not crawl off a table, ete. 
2nd day.—The irritating substances used on the first day produce 
more marked effects. 
No positive evidence is forthcoming as regards milk, but sugar seems 
to be agreeable. 
When salt is put in the mouth it is rejected doubtfully, but aloes 
most decidedly. Both are used in solution. 
5th day.—Irritants affect the puppies through the nose at a greater 
distance. 
It remains doubtful whether meat is smelled or not, but milk and a 
solution of aloes seem to be, for the puppies cease to make their charac- 
teristic sounds when these substances are placed before the nose. 
They do not yet seem to show any shortening of the latent period of 
reflex action on pinching. 
Ith day.—None of them show any signs of opening of the eyes. 
10th day.—When blistering fluid in a bottle is brought near, active 
movements result ; the head is lifted up, the tongue put out and sneezing, 
etc., follows. 
Now when a solution of salt of the same strength as that used before, 
is presented it is rejected and there is frothing at the mouth, ete. Much 
disgust is also shown towards aloes; with milk the result is not pro- 
nounced, but with sugar there is undoubted enjoyment. 
Eyes begin to open. 
19th day.—On clapping my hands and uttering “hist” vigorously 
the ears are moved indicating the ability to hear. 
20th day.—Evidence of hearing as above at the distance of four feet. 
A piece of meat put within a half-inch of the nose of one of the 
puppies causes it to move towards the object and lick the lips. The same ' 
follows when cheese is used. When the same experiments are tried with 
sleeping puppies they also lick the lips. : 
Stamping with moderate force on the floor of the kennel (concussion) 
within two feet of the puppies rouses them far more effectively than a 
sound of considerable loudness. 
One of the puppies is brought into my study. It moves about— 
crawling rather than walking, with its tail carried or held much as in a 
turtle—the hind-legs being much spread out. 
No great uneasiness manifested. 
The puppy is a picture of healthy vegetative existence. 
The incisor teeth are appearing. 
As an evidence that the puppy is influenced by the change in the 
environment, it may be mentioned that the cheese and the meat do not 
produce now the effects they did when the puppy was in its own pen.
