I. PROBLEM AND METHOD. 



This paper gives an account of some experiments which were 

 made for the purpose of determining to what extent imitation is a 

 factor in the development of the cat. It is a continuation of the 

 study of imitation which was begun with the white rat.- 



The experiments now to be described were made with four 

 Manx cats, a mother cat and three kittens, which I have designated 

 by the letters M, X, Y and Z.

My experiments were begun in October, 1906, and concluded 

 in March, 1907. During this time I fed the cats bread and milk 



1 This investigation was carried on under the direction of Doctor Robert M. Yerkes, to whom I 

 am greatly indebted for the suggestion of the problem and general method.
