132 ANIMAL INTELLIGENCE 



A small Bedlington terrier bitch that had never had 

 puppies was placed amongst them. All rushed around 

 her and tried to suck her undeveloped teats. Then a 

 St Bernard bitch, nearly as large as their dam, was 

 placed in their compartment. Though from their mode 

 of sniffing it appeared that they recognised this animal 

 as a stranger, they soon tried to suck her also. 



When they are spoken to in a friendly way they wag 

 the tail and give other evidences of sociability by the 

 face. They get up on the edge of the pen with forelegs 

 when either the dam or any person is about to leave 

 them, and follow with the eyes, and evidently would 

 with their limbs if they could get out. 



They are not now nearly so easily fatigued by any 

 stimuli, being able to last out three or four times as 

 long as they could eight days ago. 



29th day. Puppies follow a small object at a distance 

 of 7 feet. 



A high-pitched, peculiar sound causes ear reflexes and 

 barking, while a low-pitched sound, imitating barking, 

 has very little effect. 



When a small piece of cloth is dangled before the 

 face of the puppy, it tries to catch it with the mouth, and 

 raises one foreleg at the same time, as if to assist in this. 



Noticed well-executed scratching. 



They seem thus far to prefer milk to broth or meat. 



30th day. I did not make special notes of observa- 

 tions on this day. 



31st day. It seemed that to-day the dam was un- 

 doubtedly recognised by sight alone. 



When a bone and the napkin used in the last test of 

 this kind were presented to the puppies, each one at 

 once selected the bone. No chewing of the napkin, which 

 shows a distinct advance since the 28th day. 



They now observe a small object at any part of their 

 kennel compartment, i.e. at 12 to 15 feet.
