in confequence of thefe Difcovericsj all thefe were 
reciprocally communicated 5 we made a Secret of 
nothing to each other. Thus where one Truth 
feems to lead to, or is the natural Confequence of an- 
other, it will be eafy, from the Order I have ob- 
ferv d, to fee how much I have been obliged to his 
Penetration and Forefight. But this will yet appear 
more diftin&ly, when our feveral EfTays upon this 
Subject fhali appear , and in the fecond Volume of 
his Natural Hiftory, which will very foon bepublifhed, 
I muft declare for a Faft, that all which precedes his 
Accounts of the Experiments, begun March 16 , 
JSl.S. of this prefent Year 1748, was previous either 
to his own Experiments or mine, and was read to 
me by himfelf. 
§ 23. In this Order of Time therefore Mr. de 
Buffon not only repeated the Experiment I have 
taken notice of, and added particular Obfervations 
of his own, but made fome intirely new in every 
iefpe£t, peculiar to himfelf. Among thefe, that ne-

and fhews the real Ufe of thofe reddifh glandulous 
Bodies obferved by V'allifnieri upon the Teflicles 
or Ovaries, as hitherto call'd, of Cows. Every

Scars of Eggs fecundated and diflodg'cL Vallifnieri ,
