THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 211 



When in the house to-day he manifests shyness or 

 appreciation of the strangeness of his surroundings. 



When his head is stroked he acts somewhat as a cat. 



Has begun a sort of playing with his dam. 



The social tendency is clearly evidenced. 



38th day. Has grown much. There is a great change 

 in his attitude, manner of walking, etc. The puppy can 

 now run fairly well. 



He has wonderful control of his tail, moving it when 

 he approaches vigorously, as an old dog. 



For a week past his social tendencies towards human 

 beings have been very marked. 



He is now provided with, practically, his full comple- 

 ment of teeth 



His eyes and general facial expression have also greatly 

 changed. 



He is still readily startled by sounds. 



He as yet reposes a good deal, which perhaps accounts 

 in no small degree for his perfect health and excellent 

 state of nutrition. 



He now sees small objects at a distance of 8 to 10 

 feet at least. 



He is ready to eat almost anything given him. 



He can now lite accurately at any part of his 

 body. 



39th day. His weaning is begun regularly to-day. 



4:2nd day. The following experiments were tried to- 

 day : When a finger was put in his mouth he sucked 

 it, but he would take no notice of a stick presented in 

 the same way. Bread he tackled at once, using his back 

 teeth to crush it. Meat he devoured eagerly. He had 

 received no nourishment of any kind for one hour 

 previous to these experiments. 



4t5th day. Puppy is brought into my study. Shows 

 little or no shyness after a few moments. He is inclined 

 to move about and use his nose in an investigating way.
