312 G. V. HAMILTON 



Observation 27. 3-Kate-M-r (mature) was severely bitten by 

 a dog while she was at large. Her tail was almost completely 

 denuded of skin and fur, and her body was lacerated in places. 

 She was put in a cage by herself for a week, then made accessible 

 to 10-Timmy-M-c (mature). She was still weak and inclined 

 to mope. Like Gertie in observation 26, she fled from the male, 

 and assumed the sexual position only when she was cornered. 

 The animals were separated as soon as it was apparent that her 

 assumption of the sexual position was a purely defensive measure. 



Situation 17. Young sexually mature male attacked by 

 sexual' y-mature female. 



Observation 28. 11-Grace-Papio — (mature) was admitted to 

 the cage occupied by 28-Scotty M — . Scotty was sexually 

 mature in the sense of being able to discharge the full sexual 

 function, but had not yet attained adult size, and was very timid. 

 Grace advanced toward him, barking and threatening an attack. 

 When she began to bite him he assumed - the female sexual 

 position, whereupon Grace mounted him, smacking her lips. 

 She made no copulatory movements, and at once dismounted 

 and assumed the female position. The male then copulated 

 with her. 



Situation 18. Infant monkey in danger of attack. 



Observation 29. 13-Tiny-M-cr (age 5| months) was moment-' 

 arily abandoned by her mother (7-Becky-M-r) while the latter 

 sat upon the sleeping box roof and fought the members of the 

 alley band through the wire netting that separated them. Tiny 

 was whimpering and running back and forth when 11-Grace- 

 Papio — dashed at her, barked, and clawed at the netting. 

 Tiny's assumption of the sexual position had the appearance of 

 a pure reflex, so quick was it, and so quickly followed by a retreat 

 to her mother's arms. 



Observation 30. 24-Mutt-M-cr, when 6 months old, was 

 observed to assume the female sexual position while his mother 

 was absent from the shelf. He was whimpering and running 

 back and forth on the shelf, when 10-Timmy-M-c (mature) 

 threatened him from the other side of the netting. The infant 

 assumed the female sexual position momentarily, then fled down 

 the side of the cage to his mother. This kind of behavior may 

 have been manifested earlier.
