more rational to Dr. Tyfoti^ than that which Gaffendus urges^ 
from the flrudure of the teeth 5 tho' it muft be owned, he 
hath omitted nothing, that could have been faid to favour it : 
But before Dr. "ityfon v/ouid more particularly confider Dr. 
JFallis's HypothefiSy he remarks that had man been defigned by 
nature not to have been a carnivorous animal, no doubt there 
would have been obferved, in fome part of the world, men 
which did not at all feed upon fle/h 5 but fince iio hiftory (as 
Dr. lyfon knows } furnilhes us with fuch an inftance, he can- 
not but think, that what hath been done univerfally by the 
whole fpecies, muft be natural to them.- What the 'Tythago- 
reans did, in abftaining from flefli, was upon the notion of a 
Metempfychofis^ or tranfmigration of fouls, a miftake in their 
philofophy, and not a law of nature 5 and tho' in fome coun- 
tries men feed more freely on flefli, in others more fparingly, 
this is owing to their own choice, from the advantage they find 
thereby 5 nature having given mankind reafon, they can, or 
ought to chufe what food they find mofl: agreeable in the cli- 
mate wherein they live 5 and are not determined to any one 
fort, but have liberty to ufe allj and it is as probable, the ante- 
deluvian world had fo Iikewife 5 wherefore Dr. T'yfon^ wholly 
acquiefces with Dr. Wallis's determination of this point. 
To confider it as a queftion in natural philofophy 5 whether 
from the obfervation of the ftru£ture of the parts in man, we 
can find reafon to think nature did, or did not defign him to 
be carnivorous 5 Dr. ^-/yjo/i is of Gajjendus's opinion, viz. that 
from the conformation of the parts of the human body, we 
may form conjectures concerning their mere natural functions $ 
for all the knowledge we have of the ufesof the parts in animal 
bodies, is by obferving nature's wonderful contrivance in their 
formation, which moll wifely adapts them to the ufes they are 
defign'd for^ not becaufe they are cafually fo and fo formed, 
they are neceflarily put to fuch and fuch ufesj but therefore 
they are fo contrived, that they may perform fuch offices in 
the animal oeconomy as nature intends them for 5 and Dr. Ty^fori 
gives feveral remarkable inflances, in his treatife of liomo 
SylveftriSy that fufficiently confute fuch unphilofophical atheifts. 
Dr. Tyfon takes Dr. IVallis's, obfervation, from the different 
formation of the intefl:ines in carnivorous animals, from thofe 
that arc to be found in fuch as do not feed upon flefli, to be of 
far greater weight, and to carry more ftrength in it, than any 
thing he ever met with before 5 he therefore, firfl: of all ob- 
fervcs, that the 2)u5lus alhnentalis, for fo he calls the Gula^
