cannot be found, having, in all probability, been picked

Remarks on the Diary. 
Since I propose to make a comparison between the 
development of the dog and the cat in another paper, 
by which more instructive results may, it is hoped, be 
reached, the remarks that follow are to be considered 
rather in the light of suggestions as to some of the 
ways in which the diary may be utilised than as a 
commentary at all complete. 
It will be seen from the records that the evidence for

perienced first about the 9th day through the sense of 
hearing, if we except that uneasiness and crying that 
results almost from the first when the animal is removed 
from its usual surroundings. 
The spontaneous movements of the ears, and more 
doubtful movement of the tail, on the 10th day, are 
worthy of note. 
Attention is called to the advances in vision as noted 
on the 11th, 13th, 14th, 18th, 22nd, 25th, 26th, etc., 
days. 
On the 8th day the eyes began to open, but hearing

On the 11th day winking is caused reflexly by the
