flefh (as it is the common food of carnivorous animals, is not a 
natural food for us , and he does not know that any nation has of 
choice uled to feed on raw flefh, unlefs in cafes of extremity, 
^r. If there be any fuch, he looks upon it as an anamolous 
cafe, as alio the rat's eating bacon ( which yet is not quite void 
of coftion) for want of other food , and as to iwines fometimes 
eating poultry, Dr. Wallis does not take it to be purely na- 
tural, but rather the effect of an appetite depraved by cuftom ^ 
becaufe much of .the hog-wafh, which is given fwine, comes 
from the coflion of flefh for our own ufe 3 and this inures them 
to the tafte of it. 
Dr. Wallis leaves it to be eonfidered from what reafon, for 
what ufe, and in what degree the paffage of fle/h thro' the ali- 
mentary du6t, ihould ordmarily be more quick, and that of 
herbs more flow, and in what degree it is lb 5 and again, whereas 
nature feems to have originally defigned a large Cdecum in man, 
as in fome other animals ; how it comes to pafs, that in adults it 
is of little or no ufe, but fhrinks up into an Appendicula Ver- 
mi-formis , whether or not this may not partly proceed from our 
feeding fo much upon flefh.
