294 OF THE FORMATION 



confiderable ; and, when It meets with -a fufE- 

 cient quantity of female femen, the two inftantly 

 mix, and the organic particles unite and form 

 the foetus. The whole is, perhaps, performed 

 in a moment, efpecially if the two fluids be ia 

 an adive ftate. The cavity of the uterus is the 

 proper place for the formation of the ^oetus ; 

 becaufe the femen of the male has an eafier ad- 

 miffion into the uterus than into the Fallopian 

 tubes or ovarium ; and, as the uterus has only 

 a fmall aperture, which is always fliut, except 

 when opened by the ardor of love, the materi- 

 als of generation remain there in fafcty, unlefs 

 they be diftvirbed by fome rare and accidental 

 circumftance. But, as the male fluid moiflens 

 the vagina,' before it penetrates the uterus, and, 

 as the organic particles are exceedingly adive, 

 it may penetrate as far as the Fallopian tubes 

 and ovarium. In the fame manner, as the fe- 

 male fluid is already peifecicd in the glandulous 

 bodies of tbe tefticles, from which it difliils and 

 moiftens the Fallopian tubess before it defcends 

 into the uterus ; and, as it may efcape through 

 the lacunae round the neck of the uterus, it is 

 not impoffihle that the mixture of the two li- 

 quors may take phice in all thefc different pla- 

 ces. Foetufes, therefore, may frequently be 

 formed in the vogina, and inflantly fall out of 

 it, having nothing proper for their retention.
