MifceUanea Curiofa. I 43 



the fame Ducts and Pores of the Rudiments of 

 thole Animals, which were in greateft forward- 

 nefs in the Ovary, and fb extend and enlarge 

 all their Parts, and at laft bring them to per- 

 fection, as Mr. Perrault does ingenioufly difc 

 courfe in the third Part of his Ejjais de Phyfique ; 

 till now at laft Leowenhoek. has difcover'd an in- 

 finite number of Animalcula in femine murium of 

 all kinds, which has made him condemn the

Now upon comparing the Obfervations and

 mals of the refpe&ive kind, without the Ova in 

 Fceminis. 



The firft of thefe feems probable from thefe 

 three Obfervations. i. That fbme fiich thing 

 has been fb often obferv'd by Malpghiw, in 

 the Cicatricula of an Egg before Incubation, as 

 the Rudiments of an Animal in the fhape of a 

 Tadpole, as may be feen in his firft, and in his 

 repeated Obfervations de formatione Pulli in 

 Ovo. x. The fudden appearance and difplaying 

 of all the Parts after Incubation, makes it pro. 

 bable, that they are not then actually formed 

 out of a fluid, but that the Stamina of them have 

 been formerly there exiftent, and are now ex- 

 panded. The firft Part of the Chick which is 

 difcovered with the naked Eye, is, you know, 

 the Pnnttum {aliens, and that not till three days 

 and nights of Incubation be paft j and then, on
