44 WESLEY MILLS ON 



On every occasion if they see or smell the dam (that is seldom with them now as they 

 were gradually weaned — the process ending to-day) they cry out. 



While this litter is an unusually even one iu physical characteristics at all events, 

 individual differences are to be observed in many directions. There are some decided differ- 

 ences in psychic manifestations. 



One, a bitch, seems to be quicker and more precocious than the rest by a great deal. 



One dog growls when feeding, as they do at present all together from one large dish. 



4Srd day. — It is warm, and two are noticed lying in a darker and more secluded part of 

 the kennel where there are fewer flies perhaps. 



It is noticed that now one often acts as does another, one seems to take its cue from another. 



éith day. — So very warm the puppies are prostrated by the heat, and lie about main- 

 taining mere existence. 



àbth day. — To-day for the first time the door of their compartment was left open so that 

 they might enter an adjoining one which is in general fitted up in the same wa}', so that the 

 environment is substantially the same. 



It was curious to note the results. It was some minutes before the puppies, the pre- 

 cocious bitch excejjted, realized that the door was really open and that they had free access 

 to a new compartment. They did not at once surmount the difliculty presented by the door 

 case only a few inches high. AVhen some of them came in and saw the water vessel attached 

 to the other side of the wire-mesh partition thej^ did not at once comprehend that they could 

 not drink from it when they saw their fellow on the distant side lapping. All this, however, 

 lasted but a very few minutes. Soon they all were busy investigating the new place with 

 nose, eyes, feet, etc. 



The new experiences evidently afiord them unusual pleasure in spite of the heat, as they 

 play more than for some days. 



To-day I first used a switch to learn what effect it would have on their crying, etc. 



They seem to make the mental association to some extent but only imperfectly^ 



One of them, as they crowded around me, was trodden upon, and this had a decideil and 

 somewhat lasting psychic effect as will be seen later. As he was running away after this 

 accident I caught him and was trying to soothe the creature, but this was not at first under- 

 stood but increased its terror. 



Later in the day they understand the whip better. I notice what may be termed icanton 

 barking as well as that which denotes but an excess of good feeling — "animal spirits." 



Now and then one turns round on another that is attempting to play with it in (piite a 

 Jieree way. 



They are running more than formerly. 



There are i)hysical changes and good growth notwithstanding the long succession of 

 liot — to them very hot — days. 



One of them is observed using both paws to scrape away the sawdust from a part of the 

 kennel floor. He then puts down his head and tries the spot. This was repeated three 

 times before the puppy lay quietly at rest. 



Actions of one are followed by similar actions in others much more frequently and 

 readily than before. 



4:Qth day. — It has been raining, the sky is dull and the atmosphere is moist, and though 

 it is still warm the puppies seem less restless and uncomfortable. They cry much less.
