210 ANIMAL INTELLIGENCE 



24th day. To-day a puppy follows a fish-bone by 

 smell, and attempts to bite at it. 



25th day. The appearance of the eyes show an 

 advance over a few days ago. 



When the dam is brought within 6 to 8 feet of the 

 puppies they seem to become aware of her presence by 

 smell first of all, but when within a few feet of them 

 they follow her with the eyes. 



There is a decided improvement in locomotion. 



The puppies now have all the upper incisors, the 

 canines above and below, and two molars above and 

 two below. 



Hearing is now very acute. A very feeble " Hist ! " 

 when within a couple of feet, causes movement of the 

 ears, turning of the head, and an expression of the 

 face that indicates clearly that the puppy hears. 



A " Hist ! " of moderate intensity is heard readily at 

 5 feet. 



There is a tendency now, when any object is placed 

 before the puppies, to growl or bark at it in a meaning- 

 less way. 



3lst day. To-day a slight sound caused a starting. 

 The puppy (henceforth the only one) seems to have 

 reached that period when hearing, as a mere sensation, 

 is perfect, but the interpretation of sounds very 

 imperfect, hence he is startled by many sounds that 

 later produce no such effect. When a bone is placed 

 within 4 inches of him he sniffs at it, and gets up to 

 secure it. 



He makes the first attempts at gnawing a bone, using 

 his paws to steady himself, and once lifts a paw as if to 

 place it on the bone, but does not actually do so. 



The puppy now evidently sees small objects at some 

 distance quite well. 



He now stands quite erect on his legs, and to-day 

 climbs over the rungs of a small rocking-chair.
