42 WESLEY MILLS ON 



with his tail up, and several make quick starts forward and backward. On giving the lip- 

 call and snapping mj- fingers one, a few feet distant, ran towards me. 



Thej' now watch what is being done near them somewhat attentivelj-. 



A slight tap on some boards above them causes them all to move quickly away with 

 tails down and other expressions of fear. 



Sith day. — Tested them with a napkin and Spratt's dog biscuit as on the 28th day. 

 Now they all show very decided preference for the biscuit which is not so attractive as a bone 

 to any dog. One or two began to smell about the floor of the pen as an old dog does, and 

 yesterday one was observed scratching at a spot on the floor where some excrement had been. 



At this age puppies have very sharp teeth, and it is not very uncommon now to hear 

 one cry out when his fellow uses his jaws too freely in play. 



Scratching is more common. 



While the winking reflex from a simple movement of the hand as before is not readily 

 produced, a sudden tap on the ledge of the pen will cause winking if they are looking that 

 way and within a foot or so of the spot struck. They also wink when the muzzle is sud- 

 denly touched. 



35</i. daii. — They now retire to one end of their pen to answer nature's calls. 



They are noticed smelling at the shoes of any one who happens to l)e near them. 



They hark in sleep like older dogs. 



When the finger is thrust into the mouth some suck a good wbile, some not at all. 



36</t day. — They follow me around their kennel compartment and are inclined to seize 

 the skirts of a very long coat I wear. By way of testing recognition of the dam, she and 

 her other pupp}', eight months old and nearly as large as herself, were brought to the pup- 

 pies together. They all at once rushed to the dam. But soon after her removal they 

 attempted to suck the younger bitch, though from their snifl&ng it seemed to me they 

 noticed her strange. 



Later in the day the small bitch (Bedlington terrier) used for a similar test before, was 

 placed among them. They soon tried to suck her teats, at which on account of her smaller 

 size they could readily get. 



S7th day. — Being a warm day the puppies feel the heat a good deal ; lie fur apart from 

 each other and pant with tongues lolling out. 



At the distance of 10 feet a mere word uttered in a low voice rouses one that is drowsing. 



Out of five tested only one sucked when the finger was introduced into the mouth. 



SSth day. — They gave evidence of seeing me well though I was standing at an outside 



door of the kennel with two wire mesh partitions between, and at a distance of about 12 



feet. 



Upon dangling a rope over their heads one seizes and pulls at it; but when doing the 



same with a bright chain the}' make oft", showing fear. This was probably owing to the 



noise it made, the brightness, and in one case to the puppy having come in contact with it. 



The compartment in which they are kept is closed by a heav^^ wire-mesh door, through 

 which every exit must be made. They crowd around this often now and sometimes whine 

 there when hungry. 



S9th day. — High temperature ; puppies very uneasy. 



Seeing me at some little distance one of them u:ags the tail like an old dog, showing its 

 sociable and friendly nature.
