HEALTH AND SEX IN HIGHER EDUCATION. 607 



For purposes of comparison, the value of the statistics is vitiated 

 by the fact that the date of the admission of women is not given, and 

 this, in the cases of the co-educational college, does not agree with the 

 date of organization. Other facts, which we omit, go to show that 

 the average date of admission, Oberlin being excluded, may be safely 

 put at about 1870. 



The questions involved in the inquiry were exceedingly compre- 

 hensive, and may conveniently be considered under three heads, of 

 which the first takes up the conditions of childhood, comprehending 

 date of birth, nationality of parents, surroundings in childhood, 

 amount of exercise received between the ages of eight and fourteen, 

 the age at which study began, the age at entering college, and the age 

 at graduation. The second section relates to individual health, and 

 comprehends physical condition ; nervousness ; the age at beginning 

 of the menstrual period ; the conditions attending the menstrual pe- 

 riods ; the number of graduates reporting disorders ; the number of 

 disorders ; the number reporting each disorder, and the causes of dis- 

 orders. 



From the broad data thus obtained, the third section, a series of 

 comparison tables, is gathered. Of these one of the most important 

 compares the present health of graduates with the age at beginning 

 study, the age at entering college, the time entering college after 

 the menstrual period commenced, the amount of out-of-door exercise, 

 and hereditary conditions. Another compares the health during col- 

 lege-life with the age at entering, the amount of study performed, the 

 amount of worry about private and college aifairs, etc. The first set 

 is thus seen to be occupied with giving a picture of health through 

 life, while the second endeavors to ascertain the changes introduced by 

 college-life, and their causes. 



The general features of the tables may be stated as follows :
