THE EXPERIMENTS. 245 



in difTeiSling a woman who had been killed im- 

 mediately after the adt of adultery, he found a 

 confiderable quantity of male femen, not only 

 in the uterus, but in the Fallopian tubes *. Valif- 

 nieri likewlfe affuresus, that Fallopius, and other 

 anat-omifts had difcovered male lemen in the u- 

 teri of feveral women. This point, therefore^ 

 though denied by Harvey, is eftablifhed by the 

 pofitive tcflimony of feveral able anatomifl;Sj and 

 particularly by Leeuwenhoek, who found male 

 femen in the uteri of many different fpecies of 

 females. 



Harvey mentions an abortion, in the fecond 

 month, as large as a pigeon's egg, without any 

 appearance of a foetus. In this alfo he mull 

 have been deceived; for Ruyfch, and feveral o- 

 ther anatomifts, maintain, that the foetus is di- 

 ftinguiihable by the naked eye, even in the lirft 

 month of pregnancy, in the Hiltory of the 

 French Academy, we have an account of a foe- 

 tus completely formed on the twenty-firft day 

 after impregnation. If, to thefe authorities, we 

 add that of Malpighius, w^ho diftinguiihed the 

 chick in the cicatrice immmediatcly after the 

 egg ifl'ucd from the body of the hen, we cannot 

 helitate in pronouncing that the foetus is form- 

 ed immediately after copulation; and, confe- 

 quently, no credit is due to what Harvey fays 

 concerning the increafeof the parts byjuxta-po-* 

 fition; fmce thefe parts exift from the beginning,
