which goto the mufcles of the neck; 3. arteria mujcule, which are approximate to 
the jugular veins; 4. the, carotides, or fleep-arteries, which, are two, unequal, and af 
cend. upwards to the head by the fides of the wind-pipe, being. knit to the internal 
jugulars: when. they come to the  fances, before. they enter the fcull, they give 
branches to the /aryax and tongue, and then they d ivide themfelves into the carotis 
‘ externa and carotis interna, The carotis externa, being the {maller, fusnithes the cheeks 
and mutfcles of the face: at the root of the ears it is divided into two branches; 
| the firft is fent to the hinder part of the ear, whence arife. two other. branches, 
which go to the lower jaw, and the root of all the lower teeth : the fecond goes to » 
the temples, the forehead, and mufcles of the face. The. corofis interna at the 
faddle of the os /phenoides, under the dura. mater, makes the reta mirabile, then 
-paffes through the dura mater, and fends forth two branches: the firft, which is the 
fmaller, goes with the optic nerve to the eyes: the fecond, which is the greater, af- 
cends to the fide of the glendula pituitaria, and is diftributed ihc the bite mater 
and the fubftance of the brain. | 
When the fubclavial branches have left ai breaft or shinies they are called olan: 
and carry nourifhment tothe outward part of the breaft, and tothe whole arm. From 
the axillares axife the thoracica, fuperior, or upper breaft-artery; thoracica inferior, or 
lower breatt-artery; the /cupularis, or fhoulder-blade artery. From the upper part 
of the fame axillaries arifes the Aumeraria: the remainder goes from the, axillary on 
each fide to the arm; where it is carried along through the arm, defcending-be- 
tween the mufcle, with a.vein and nerve of the arm. Under the bending of. the 
elbow,.i it is\divided into two branches, the upper and the lower, which accompany 
the branches.of the vena cava, and are called by the fame names. The upper goes 
~ right forwards through the middle to the wrift, where the pulfe is commonly felt : 
"from thence, proceeding under the ring-fhaped ligament, it beftows branches upon 
>the thumb, fore-finger, and middle-finger. The lower branch runs through the 
- lua. to the wrifts, and fends twigs to the ring or little fingers, and fo proceeds to 
“the wrift beneath, wheré'the pulfe may alfo be felt, efpecially in fuch as are lean, 
and havea ftrong pulfe; but the beating of the pulfe is much better felt in the 
iat branch, that being lefs covered or hid by the tendons. : | 
‘The defcending trunk of the aorta fends out branches from itfelf unto 0 the thorax, 
. ini and thighs. From the'thorax it fends forth two arteries: 1. the interco/-
