120 K. S. LASHLEY AND JOHN B. WATSON 



At other times he tries to creep under her arm, but does not 

 attempt to push it aside with his hands. Once he succeeded in 

 throwing himself forward over her arm and stood alone. She 

 caught him by one leg and pulled him back, then put her other 

 hand around his neck and drew him into place. 



He gives a scratching reaction today for the first time. The 

 hind foot alone is used, scraping clumsily at his back and head. 

 The movements are slow and uncertain. 



He has grasped at several objects but does not pick them up, 

 and he reaches out toward his mother's hands when she moves 

 them.' He frequently puts his hands in his mouth, especially 

 fater he has scraped them along the ground, or has grasped at 

 some object. 



Some of his movements indicate a lack of distance percep- 

 tion. Gazing intently at some object (carrot) he throws himself 

 violently forward over Dolly's arm, at the same time reaching 

 out with both hands, as though in an attempt to grasp it, although 

 it is as much as three feet away. 



While he was facing away from her Dolly became frightened. 

 She leaped to her feet, grasping him around the throat, and 

 started to run away. When he cried out she stopped, looked 

 down at him, then grasped him by one hind leg, turned him 

 over into position, and ran on. 



He now turns directly towards the source of sounds and 

 follows movements accurately with his head. He attends much 

 longer than at first, looking at the observer as long as half a 

 minute at a time. Unlike the adults, he meets the eye readily. 

 He would not reach toward a moving hand or a stick thrust 

 into the cage. 



July 23. The caretaker reports that the baby was out of 

 Dolly's arms and walking for the first time at 10.00 A. M. today. 

 At 1.30 Dolly climbed up on the gate. The baby dropped 

 down between her thighs and hung by one hand for a few 

 moments. When she is walking he clings to her tightly but 

 the moment she stops he tries to escape. I gave Dolly a bit of 

 chocolate. While she was eating it, the baby began to creep 

 away. She put out a hand to stop him, thought better of it, 

 and walked away a couple of feet, looking back at him. He 

 began to crawl after her but his hind legs were too weak and 

 he fell over. As he approached Dolly moved farther away, and
