246 ANIMAL INTELLIGENCE 



After the first month of existence comparison with 

 the dog, cat, and allied creatures ceases to be suggestive. 

 The rodents are left quite behind. They seem capable 

 of little education either by man or by nature. In 

 other words, they get little from experience beyond 

 that which strengthens their instincts and emphasises 

 their simple psychic life. 



During this rapid psychic development, physical 

 changes of an equally rapid and decided character take 

 place, and are undoubtedly correlated with the psychic 

 changes. 



VI. THE PIGEON THE DOMESTIC FOWL. 

 The Pigeon. 



So far as I am aware, no investigations on birds of 

 the kind set forth in this paper have been made, except 

 in the case of the domestic fowl and the pheasant. As 

 my observations on the pigeon are the most complete, 

 they will be recorded first. 



I have bred a large variety of pure-bred pigeons for 

 many years, and have kept notes on a considerable 

 number of subjects relating thereto, but the following 

 are the most complete consecutive records bearing on 

 the psychic development of pigeons that I have made, 

 and are accompanied with a fairly complete account of 

 contemporaneous physical changes; and I trust that 

 so long an acquaintance with pigeons may be some 

 guarantee of correct observation and interpretation. 



majority showed distinct ' character.' I selected the two in which 

 this was most marked. One associated himself with my cats and 

 fowl, and protected the young chicks by driving away strange cats. 

 The other associated with the family and children, and its actions to 

 me were those of a very attached dog. It appeared to take an interest 

 in everything I did, sat beside me when I was analysing, and moved 

 among my apparatus with the caution so often noticeable in the cat."
