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

On the llth day winking is caused reflexly by the
