*'In this Enquiry indeed, tvhich we are now attempting, no less 

 useful than agreeable, the Wits of almost every Age have toiVd: 

 hut as there is hardly any Argument, on which Physicians have 

 wrote more; so is there no one, in which they have given less satis- 

 faction to their Readers. . . . I shall not appear to have employed 

 my Time ill, in endeavoring to set the Nature of the Menses in a 

 clearer Light, than I find it hitherto done by Authors. In which 

 Performance the Reader will find nothing abstruse, nothing far 

 removed from common sense: inasmuch as it has been my only 

 Care to find out the Truth, as much as possibly I could." — John 

 Freind, Emmenologia, translated into English by Thomas Dale, 

 1729.
