pofture: The heart, in proportion to the animal, was large, and 
the liver fmall : The tongue was broad and thick, at the extre- 
mity Ibmewhat like a man's, whence a parrot hath its name 
rt>Qp«y7r©Q/Afe)TT<^ 5 its extremity was armed with a horny cover : 
It has, befides the gizzard, two craws, the uppermoft being only 
a receptacle, or fack for the food, which is canary-leed, to be 
again returned to the mouth, where it is re-chewed, having 
before been only hufked, this animal ruminating as fome quadru- 
peds do j and Mr. IValkr oMervcd this bird, when upon the perch, 
not only bring up its food again into its mouth, and there chew it. 
but when the cock and hen fit together on the perch, he would 
put the food out of his own mouth into the hen's 5 their manner of 
chewing is thus, the under bill, being much fliorter, fliuts within 
the upper, or againfV theroof of the mouth, which is fitted with 
leveral rows of very fmall crofsbars, as the mouths of horles, 
dogs, and fome other animals are j thefe bars are not fofr, but 
horny, as being part of the upper bill; fo that the bird, by car- 
rying the edge of the under bill and end of the tongue, againfl 
the ridges in the upper, breaks and reduces to a pap the feeds 
that have been firft moiftened in the craw, to expedite which 
a61ion, the upper bill is joined jufl below the eyes ; the food, 
being thus macerated, is by the Gula again committed to the 
lecond craw, but before its entrance into it, it paffes by a number 
of fmall glands, placed in that part of the Gula ^ that the food 
may iqueeze out of them in its paffage, a juice, of what necef^ 
fity in digeftion may be enquired 5 from hence the food paffes 
into the gizzard, or proper ventricle, fmall in comparifon of the 
Inglumes-, or crop; where, by feveral flones picked out of the 
land given it, and by the motion of the gizzard, it is comminuted, 
and thence tranfmitted to the inteftines, on the fides of which, 
within a fmall diftance, is placed the Pancreas.
