38 WESLEY MILLS ON 



However when they are held up before a good light they follow with their eyes the 

 movements of the hand or other object, nevertheless when they reach the dam from the distant 

 part of the pen it is difhcult to determine how much they are guided by sight and how much 

 by smell. I am convinced that while the former is an aid, smell is still the most useful to 

 them in all such cases. 



The peculiar noise made with the lips to attract the attention of dogs, which I may 

 term the lip-call, is evidently' heard, and as the position is shifted the puppies follow the 

 sound to right and left. While the dog whistle is heard it causes reflexes of the ears and 

 some startling but does not rouse them so thoroughly into movements as the lip-call and cer- 

 tain other sounds. 



When an attempt is made to plug the nostrils with cotton wool, it is at once sneezed out 

 reflexl}'. 



Judging by the whining and crying after fasting, hunger is more keenly felt than ever. 



A bandage placed over the eyes soon causes sleep. 



Up to the present date the only nourishment received has been the mother's milk, but 

 to-dav artificial feeding with cow's milk diluted was added. The first attempts at lapping, 

 though far from perfect, were fairly good — much better than the first attempts at swallow- 

 ing fluid artificially introduced. It is noticed that they follow up slowly the spots where 

 milk had been spilled. After each feeding they lick each other's faces thoroughly.' 



\Wi day. — The attendant reports the puppies as harking when he entered, as if at him. 



The lip-call, at a distance of six to eight feet, causes them to prick up the ears quickly 

 which is soon followed by crying (expectancy of food possibly). 



One of the puppies scratches his own ear. 



Teeth are appearing that for some days could be felt beneath the gums. 



20th day. — Some get additional teeth. 



21.5^ day. — Certain motor manifestations are worthy of special mention. 



Tails are wagged during play, and walking with tail held erect is seen for the first time. 



Several of them tried to get out of the pen. 



When the muzzle is held by the hand both hind legs were used in an attempt to re- 

 move it. (Will or reflex ?) 



The hand moved before the face as if to strike, causes winking. 



Now they seem to hear almost every sound made in their compartment of the kennel 

 which is about 15x6 feet. 



22nd day. — Some have all the upper incisors, and in one case the nose is all but covered 

 with tlie characteristic black ]iigment, though this one is in advance of the others in this 



respect. 



2Srd day. — On my return on this day a long time was spent with the puppies and the 



following noted : — 



The dam is no longer so much inclined to stay with her offspring and does not wish to 



suckle them so frerpiently. 



The puppies are fed on the top of a large box, two at a time. It is found that unless 

 straw is placed on the top of the box the puppies will not feed. They decline to take half 



' During four days I was absent from home, but the puppies were carefully watched and notes taken by mem- 

 bers of my family who are familiar with the ways of dogs, and had frequently been with me when making my 

 investigations on this and other litters of puppies.
