THE PSYt'llR' DEVELOPMENT OF YOUNG ANIMALS. 43 



When one speaks the}' show pleasure by the tail, expression of face, etc., 

 Two bones from cooked meat were placed on the straw of their pen, which now has 

 walls onl}' a few inches high, so that they can go in and out easily. 



One or two go towards the bones followed by others ; one seizes a bone and walks out 

 of the pen with tail up much in the manner of an older dog. I suddenly removed the bone, 

 when the puppy that had it sniffs about, going back over his track evidently guided by the 

 scent it had left. 



Some of them that had followed up the puppies that had taken the bones return to the 

 straw, seeking them. 



The removal of a large piece of tin that had been used to encircle a stove in a protective 

 way, made a noise which caused them all to rush away as so many sheep ; but when I gave 

 the lip-call they soon recovered and came towards me. 



Given ukiter in a vessel to drink for the iirst time, they merely dip into it. 

 iOih dai/.—Bemg decidedly cooler they do not whine or cry, but play much. 

 One is seen violently shaking a piece of paper that was in the straw. 

 Another is seen scratching his head with the latter inclined towards his leg in the man- 

 ner of a mature dog, though witli much slower movements. 



To-day one is seen to lap water when it is poured into the vessel attached to the wire- 

 mesh partition, whereupon several others do so. 



In the evening one is noticed moving about in the way peculiar to an old dog prior to 

 defecation. 



"When any one enters the kennel the puppies now run about his legs eagerly. 

 They have almost deserted their pen and lie about on the floor of their kennel com- 

 partment, finding it cooler, while the layer of sawdust makes it soft to rest upon. 

 ■ilst dag. — Their pen was wholly removed to-day as it served no good purpose. 

 They occasionally lie so that the head and body is in a fashion supported e.g. against 

 the partition or walls of the kennel or with the head on a part of the floor that is there a 

 little raised. 



A very slight growl at the outer door of the main kennel with three partitions or walls 

 between (doors being open) causes one of them, though lying apparently asleep, to get up, 

 and if anything happens they all awake if one moves much or whines. 

 One of them is observed to snap at a fly. 



At 10 p.m. I notice one of the puppies scraping away the sawdust near the elevation 

 referred to above on which he had laid his head in preparing to rest. He tried the spot 

 once or twice before he finally laid his head down. 



i2nd day. — It is very warm and the puppies whine and cry a good deal owing to the 

 discomfort as their coats are thick and warm. 



Now there are many evidences that they hear as acutely as mature dogs if not more so, 

 and sounds disturb them more as they do not know their meaning so well. 



They now show an interest in everything that goes on within their field of examination 

 with eyes, nose, etc. In fact it is difficult to move about among them. 



"When they see one, they may cry out if hungry, Avag the tail if recently fed and satis- 

 fied, sniff", etc. 



This sniffing is a characteristic method of investigation with dogs, and its appearance at 

 this date and earlier is significant.
