ments of the Head, the Mufcles that raife the poifon- 
ous Fangs appear • the firft of which arifes with a fhortr 
flefliy Beginning from the upper Edge of the lower 
Jaw, near the Articulation of one of thofe Bones which 
Dr. Tyfonc alls Maxillarum 'Dilatores (See Fig. i. A.) 
and fends a few carnous Fibres to the Side of the Cra- 
nium *, then becomes tendinous, and fo marches to its 
Infertion in the Outfide of the Bone which receives 
the poifonous Fang. ( See Fig. 2. ) Difplacing this 
Mufcle there appeared a Gland , (See Fig. 1. B.) about 
the Bignefs of a fmall Pea, which I take to be one of 
the Maxillary Glands, for the following Reafons: 
Firft , The Stru&ure of the Parts and its Diflance from 
the Fang make it unlikely to be defign’d for feparating 
the poifonous Fluid, but rather a Saliva to moiflen 
the Aliment, in order to make it pafs down the Oefo - 
phagus with Eafe, the Stomach of thofe Animals be- 
ing but fmall, and the Gullet confiderably larger • not 
without fome Analogy to the Ingluvies or Crop of Gra- 
nivorous Fowls, where the Food flops for fome time 
and is moiflened, before it is capable of defcending 
into the Stomach. Secondly , Thefe Parts are fo con- 
trived, that on opening the Mouth to receive the Prey 
(at which Time fuch a Fluid is mod wanted) the 
Mufcle above mentioned prefling on the Gland pro- 
motes the Difcharge of its Contents into the Mouth. 
The Fiuft of this Gland feems to open between the 
Upper Lip and the Jaw, but as the excretory Dudfs 
of fo fmall a Gland are rarely to be feen with Certain- 
ty, I won’t pretend exactly to determine its Aperture. 
Under this Gland lies another Mufcle fmaller than the 
former, which arifes and is inferted near it (See Fig. i„
