He confirmed his difcoveries during the fol- 

 lowing years, and made additions to them. In 

 a letter tj Mr Wren, 1683, he thus expreffes 

 himfelf refpeciing the feminal vermiculi of frogs : 

 *^' Hie animalculorum numerus erat tantus, ut cre- 

 dere fubiret ad quodvis fa^mellas ovulum a maf- 

 culo emitti forte loooo talium animalculorum, 

 quge in femine ejus continentur." And in the 

 year 1699, writing to the Royal Society on his 

 theory of feminal vermiculi, fome of which he 

 believed male and fome female, he proceeds : 

 *' Si porro his addamus, quod me antehac in ob- 

 fervationibus meis animadvertere cenfui inter ani- 

 malcula ex femine virili quisdam apparuifle, qu2E 

 aliquantulum ex fe mutuo differre videbantur, 

 unde concludere non verebar, alterum genus 

 mares, alterum vero fsemellas repraefentare, atque 

 fi cogitemus idem in omnibus feminibus mafcu- 

 linis locum habere, nullus video, &c." There is 

 another paflage coinciding with this : " Sed jam 

 ubi etiam in feminibus mafculinis animalium, 

 avium, pifcium, imo etiam infedorum reperi ani» 

 iiialcula, multo certius efle flatuo, quam antea,
