the vein becomes dilated and serpentine, from the
continual influx of the blood from the artery : and this
constitutes what is called a varicose aneurism.

These three veins all unite above the bend of the arm, and
form—

The brachial vein, which, receives all their blood, and
is continued into the axilla-, where it is called

The axillary vein. This receives also the blood from
the scapula, and superior and inferior parts of the chest, by
the superior and inferior thoracic vein, the vena 7>iuscularis,
and the scapularis.

The axillary vein then passes under the clavicle, where it is
called the subclavian, which unites with the external and
iute.rnal jugular veins, and the vertebral vein which brings
the blood from the vertebral sinuses; it receives also the
blood from the mediastinal, pericardiac, diaphragmatic, thy-
mic, internal mammary, and laryngeal veins; and then unites
with its fellow, to form the vena cava superior, or, as it is
sometimes called, vena cava descendens.

The blood from the external and internal parts of the head
and face is returned in the following manner into the external
an ! internal jugulars, which terminate in the subclavians:

The fronlal, a.xgular, oifa.ial, tsmp'jrul, auricular, sublin-
gual, and occipital veins receive the blood from the parts
after which they are named ; tiiese all converge to each side
of the neck, and form a trunk called the external jugu-
lar.

The external jugular may be opened with more facility
(ban the Veins in the arm. In ophthalmias it gives
speedier and more certain relief, and in many diseases
of the head is preferable to taking blood from the arm.
The application of a bandage under the arm is useless;
simple, pressure with the linger is far better.
