‘The mufcles moving the tongue are in number five pair; 4. 2ylog/offum, ariling 
from the outfide of the appendix fyloides, and. ending with tranfverfe, fibres, in both 
fides of the tongue; it moves the tongue inwards; and, by reafon of the interwoven 
fibres, they Jift the tongue upwards, if they aft both together ; or upwards, only on 
one fide, if only one acts. 2. Mylogiefum, arifing from the fides of the lower jaw, 
at the roots of the grinding teeth, and ending under the bafis of the tongye ia the 
ligament: when both aét, they move the tongue to the pallet and upper teeth, 
but when one atts the tongue is moved obliquely upwards. 3, Geninglofium, arifing 
inwardly from the middle of the chin, and terminating almoft in the middle of the 
tongue inwardly : its ule isto thruft the tongue out of the mouth, and alf to draw 
it in again, fo that it feems to perform contrary actions. 4. Hypfilogloffion, arifing 
flefhy out of the upper and middle region of the os byeides, runs along according to 
the length of the tongue; and is terminated into the middle of it: this pair draws 
the tongueinward. 5. Ceratoglofium, which arifes from the upper horns of the by- 
vides, and is obliquely inferted into the fides of the tongue, near the root thereof. It 
moves the tongue downward toward the inward parts, when both aét5 but co the

The mufeles of the Jarymx, or windpipe, are either common or proper; the, com-

inner fide.of the ftermum, runs along by the larynx, and is inferted beneath into the 
fides of the feutiformis, or thield-fattened griftle..This ftraightens the chink. of the 
larynx, by drawing down the fiutiformis. Hyothyroides, arifes from the lower fide of 
into its bafis. It widens the chink, by lifting up the /eutiformis. Thefe common 
muscles are implanted into the Jaryrx, but do not arife therefrom, The proper 
mufcles are five pair; 1. thyrocricoides arifes from the loweft part of the /cutiformis, 
and ends at the anmuaris, and is inferted into the lateral parts of the thyraides.. 2.
