THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 131 



27th day. The puppies follow a small object (3 by 1 

 inches) dangled before them at 15 inches. 



One is observed playing with a straw 3 or 4 inches 

 from it. In this act there is the use of the mouth and 

 the fore-limb, with all that this implies. 



There is clear evidence that sounds made at the 

 outer door of the kennel, and in the adjacent yard, are 

 heard. 



A basket in which meat had been kept, and giving 

 off a strong odour when brought near the pen, is plainly 

 smelled. The dam is brought within 3 feet of the 

 puppies, but unseen by them. First one, and then 

 another begin to sniff and soon to cry. 



The playing shows advance ; better use is made of 

 the hind limbs, which develop functionally and much 

 more slowly than the forelegs. The head and neck 

 movements are also better in all respects. 



Now, and even some days since, increase in the 

 quantity and quality of the coat, with changes in the 

 shape of the head are evident; and in both physical 

 and psychic characteristics, individuality is to be 

 noted. 



To-day play seemed in one case to change into a 

 little quarrel for a few seconds. 



One is observed to utter an abortive bark in its sleep. 



28th day. Noises above the kennel in my pigeon 

 loft have greater effect on the puppies than on the 

 mature dogs in the adjoining 1 ^ kennel. 



They can now follow with the eyes the small objects 

 used in all these experiments at a distance of 4 or 

 5 feet ; while a napkin, etc., can be followed anywhere 

 within their kennel compartment. 



Various objects, as a plate, glass, a folded napkin, and 

 a Spratt's dog biscuit, are presented, but they mouth 

 all about equally, so that distinct selective choice is 

 not shown.
