Omnipotence of an All-wife Creator; and is not 
perhaps lefs extraordinary, than that Opinion which 
attributed the Regularity and Motion of the Planets 
tothe Miniftry of Angels. In this Light, I prefume, it 
has been looked upon by others, as well as by myfelf; 
and it is upon this account that I imagine it has 
had fo few Followers; I fhail therefore take no 
further notice of it here, than to obferve, that, in- 
afmuch as it admits a productive Force in Nature, 
and Operations that go much deeper than a mere 
Developement of Parts, it has certainly more of 
Truth in it, than the Opinion of pre-exiftent Germs: 
as I flatter myfelf, will appear evident in the Courfe 
of this Memoir, by Arguments drawn not from 
Obfervations only, that are obvious to every Natu- 
ralift, but particular Experiments made upon animal 
and vegetable Subfiances, during the whole Sum- 
mer of this prefent Year. 
§ io. To enter therefore more particularly into 
my SubjcCt, where to place the pre-exiftent animal 
Embryo, for inftance, whether in the Animalcule 
or Egg, was ever the Queftion, and Rill remains 
unanfwer'd. A Divifion of vital, cftcntial, and 
original Stamina or Lineaments was impoflible j yet 
innumerable Inftances in Monfters, Mules, and 
many natural Subjects, concur to prove, that the 
young Foetus partakes of the Nature, Qualities, 
Conftitution, Form, and Features of both the Pa- 
rents ; even as far as their Defeats and Difeafes, which 
are but too often hereditary. How can it then be 
agreeable to Reafon ? Or to what Putpofe fhould 
we call in to our Aid unalterable original Stamina ? 
Can the vifible Species of any Production be deter- 
v min'd
