SEXUAL TENDENCIES IN MONKEYS 297 



the observer arrives at conclusions which have no value unless 

 they are found to be justified by the facts upon which they are 

 based, and when the presentation of all the facts involved would 

 require the space of several printed volumes, some method of 

 abridgment must be adopted. An abridged journal is not apt 

 to be satisfactory where an extensive program of observation has 

 been followed unless, as rarely happens, the most convenient 

 and logical order in which the facts can be presented coincides 

 with the order of their occurrence. I have followed the order 

 of presentation outlined below for the sake of effecting a satis- 

 factory abridgment without resorting to the awkward expedient 

 of publishing extracts from my note books in journal form : 



I. List of subjects. 

 II. Description of environmental conditions. 



III. A list of the types of situations that were arranged by the 



observer or encountered by the subjects in conse- 

 quence of their spontaneous activities ; and under each 

 description of a typical situation one or more detailed 

 descriptions of typical responses thereto. 



IV. Classification of reactions as expressions of reactive 



tendencies. 



I. DESCRIPTION OF SUBJECTS 



The estimated or known age of each subject is given for 

 January, 1914. Inability to identify an animal as to species is 

 indicated by a dash after the generic name. The " pet " name 

 of each animal is given to facilitate the reader's identification 

 of subjects in subsequent descriptions of behavior. An animal's 

 sex is indicated by its laboratory number — even numbers for 

 males, odd for females. In reporting the behavior of an animal 

 the first reference to it will include, in the order given, its labora- 

 tory number, pet name and initial letters of the genus and species 

 to which it belongs. E.g., " 7-Becky-M-r " refers to Monkey 7 

 of the list, and indicates that she is a female M. rhesus. 



Monkey 1. Bridget. M. rhesus. Adult. 



Monkey 2. Mike. M. adult. About 1/4 larger than adult 

 male M. rhesus. Fur grey and luxuriant. Tail about 8 

 centimeters long and furred to the tip. Body thick, face 

 broad. Readily identifiable as a macaque.
