APPENDIX II 



Since the chapter on Human Fecundity was set up in type 

 my attention has been called to a paper by Siegel {MiincJiener 

 Medizinische Wochenschrift, 1916, p. 748). Though much has 

 been said as to the supposed influence of the time of copulation 

 with reference to the sexual cycle upon fertility, no definite 

 information has been forthcoming. This paper, however, contains 

 important data which bear upon this point. Owing to the fact 

 that married soldiers only had occasional leave from the army 

 during the war and then only for two or three days at a time, 

 it has been possible to obtain information as to the period in the 

 sexual cycle in which between two and three hundred children 

 were conceived. Siegel finds that the likelihood of fertiUzation 

 increases from the beginning of menstruation, reaches the highest 

 point six days later, remains almost at the same height until the 

 twelfth or thirteenth day, and then declines to the twenty-second 

 day, after which there is absolute sterility. 



If these data are confirmed, then those customs which en- 

 couraged copulation immediately after menstruation (as among 

 the ancient Jews) or discourage it (as among the Hindus) must 

 have an important bearing upon fertility.
