15° Mifcellanea Curio fa. 



Connexion with the Vterus from the time of 

 Conception. If you join all thefe three Confi- 

 derations together, vi%. that an A?iimalcle can- 

 not come forward without a proper Nidus or 

 CkatricuU 3 that there have been frequent Fcetuss 

 extra Vterum j and that they have no Adhafion 

 to the Vterus, for a confiderable time after Con- 

 ception, they i'eem to make it evident, that A- 

 nimals cannot be form'd ex Animal cutis without 

 the Ova in Vceminis. To all thefe 1 (hall fubjoin 

 the Propofal of an Experimentum Cruris, which 

 may feem to determine, whether the Teftes Foe* 

 'tninea be truly the Ovaria, vi%. Open the Ah* 

 domen of the Females of fome kinds, and cut out 

 thefe Tefticles, and this will determine, whether 

 they be abfblutely neceflary for the formation of 

 Animals. 



There are fome Difficulties propofed againft 

 this Conjecture, which I think may be cafily re- 

 folved. Some object the diftance between the 

 Tuba or Cornua Vteri, and the Tefticles ; but to 

 this is oppofed by Swammerdam, and others, the 

 like diftance between the lnfundibulum, in Hens 

 and Frogs, and the Ovary • and yet it cannot be 

 denied that the Eggs are tranfmitted thro' this 

 into the Vterus : And befides Z^. de Graef, and 

 others, have by repeated Obfervations found that 

 the Cornua Vteri do at certain times after Con- 

 ception, embrace the Teftes on both fides the V* 

 term. They object in the fecond place the great 

 difproportion between the pretended Eggs in the 

 Ovaryi and the Aperture of the Tuba or Cornua 

 Vteri, th c former being a great deal bigger 

 than the latter But both de Graef and Mai- 

 fighius have clear'd that Matter, by making 

 appear, that thefe Bladders in the Ovary are 

 not the Ova, but ferve to form the Glandules
