LAWS OFTHE STERILITY OF WOMEN. 



323 



siderable number of wives breeding at longer intervals, the averages just given 

 would be far overpassed. And some of these averages are, as already shown, 

 considerably less than were believed to be the true averages by writers who were 

 not thinking of the law now demonstrated, but of the ordinary rate of time- 

 fertility of married women. 



Besides, being of evident intrinsic value, the conclusions arrived at in this 

 paper will afford to medical men, means of estimating the utility of the many 

 vaunted methods of curing sterility which are now much in vogue, and which, 

 considering the nature of the condition to be cured, justly excite anxiety for the 

 honour of the profession in the minds of its best friends.
