plays about the wedge canal; and lastly, the xose artery, which is => 
transmitted through the wedge palate hole, to the cavity of thenos- 
trils. 8. Temple artery, which perforates the salival glands, near 
the ear, and sends off the crossing artery of the face, which unites _ 
with the arteries of the face ; and several branches which go to the . 
ear, forehead, and about the temples. : 
The trernav nea, or artery of the brain, leaves the external 
at the angle of the jaw, and proceeds by the eighth pair of nerves 
and rib nerve, to the carotid canal in the rocky portion of the tem- 
ple bone, where it is shaped like the letter Ff, and enters the skull at 
the side of the pituitary cavity, having given off two very small 
twigs to the nose gland, and third, fourth, and fifth pair of nerves ; 
and when it has reached the front couch process, it sends off— 
1. Eye artery, which is distributed on the eye. 2. Front brain ar- 
tery, which proceeds before the pituitary cavity, unites with its fellow, 
and forms the circle of Willis, from which a branch proceeds to the 
third ventricle, shining partition, and the artery of the callous body. 
3. A midddle brain artery, which runs between the front and middle 
lobes of the brain, gives off the artery of the net-work membrane, 
and is lost in the middle lobe of the brain. 4. The communicating — 
artery, which proceeds backwards and soon unites with the vertebral. 
THE RIGHT CHEST ARTERY arises from the First BRANCH, andthe => 
LEFT from the arch of the fountain. Each chest artery gives off 
five branches : a 
1. The internal breast, from which arise, the wart artery, tothe ~_ 
midriff, and the membrane of the heart. 2. The lower shi er = 
which arise, the shield branch arteries, the windpipe arte - 
ascending shield, and the transverse arm arteries. 3. The verte-_ 
bral artery, which proceeds into the vertebral holes, to ascend into 
the cavity of the skull, where it unites with its fellow upon the wedge - 
process of the hinder bone, and forms the basillary artery, which 
immediately gives off the back artery of the hinder brain; it then 
procceds upon the ring eminence to give off four branches, two to 
the right, and two to the left, which constitute the front arteries of 
the hinder brain, which branch to the legs of the hinder brain, the 
hinder brain, worm, legs of the brain, four twin bodies, pine-apple 
gland, and fourth ventricle; and the back artery of the brain, which — 
is joined by the communicating artery, and supply the chambers of 
the optic nerves, the double centre, the funnel, and legs of the arch, __- 
and the back lobes of the brain, uniting with several arteries. 4. 
The deep neck artery. 5. The superficial neck artery, both of which 
are distributed about the muscles of the neck. 6. Upper rib ar- 
tery, which lies between the two upper ribs. - 7. Upper shoulder 
blade artery, which sometimes arises from the shield artery, where. 
it is called the cross of the arm. sie ~ geghe 
As soon as the chest artery has arrived in the arm-pit, it 
_ called the arm-pit artery, which runs into the arm where it is called 
the arm artery. ie ; 
the arm-pit aricry gives off—1. The four breast arteries. 
blood to the muscles about the breast. 2. The un. f 
which supplies the lower surface of the s
