The Stomach and Gun. 
inch over. But the lower part, leading from it towards the 
Echinus, very {lender, not above * wide. 
The Echinus almoft an Oval fhape, being divided from 
the Gizard by a pretty long and flenderNeck. And may 
therefore be properly call'd the Second or Oval Ventricle. 
The Third, is the Gizard, in the place of the plain Bag 
or Stomach in the former Birds. Tis made of Six Mufcules 
and a Cartilaginous Lining in the greater Concave 3 which 
may be called the Laboratory. Thofe four, which make the 
greateft part of the Gizard, may be called the Grinders. 
Of extraordinary thicknefs 3 whereby the length of the 
Convex, is crofs to the length of the Concave of the Gizard. 
Yet thinner towards the Edges,fo as to make a kind of dou- 
ble Hyperbola. In the Centre hereof on both fides meet 
the Te?idons of the faid Ma/^/e^continued or expanded for 
about i an inch in breadth, without any Carneous or Red 
Fibers mixed with them. From whence, they are divided, 
the one, which is the ftronger, fpread over, the other, under 
the Mufcules 5 into which they are alfo branched all the 
way, fo as meeting in the body of the Mufcule they make 
a fort of fine Cancellated Work, as may be feen better in 
xhe Gizard of a Goofe 3 efpecially in a thin flice hereof par- 
boyl'd, and held up againft a Candle. And in all Gizards, 
fo as to be feen to run crofs, as in that of a Pullet in Tab. 29. 
The Fifth Mufcule is that which flandeth between the 
Echinus and the four Mufcules now defcrib'd, and may be 
called the Deduftor, from the ufe hereafter mention d. Very 
thin with refpect to the former 5 placed at the upper end of 
the left edge of the Gizard, and fpread a little on the fide, 
but not fo much as in the Figure. Better reprefented, 
Tab. 2 p. 
The Sixth, is fuch another Mufcule, ftanding oppofite to 
the former,/? . on the right edge of the Gizard, and may be 
called the Redutlor, as fliall be fhew'd why. 
The four Grinders are ftrengthened within,not only with 
a Tendon, but a Griftly Lining, thicker than the outer Ten- 
don, with a rough furface, and wrinkled into feveral Tranf- 
verfe Furrows, from one end to the other. 
The Guts are about a yard and 3 long. Three befides 
the Caeca. The firft, the fmaller 3 contrary to what it is 
in moft Birds. Not much, above * of an inch, where wideft.
