    branches are the ramus hyoideus, ramus super- ficialis, ramus laryngeus, ramus thyroideus. The inferior thyroid artery* comes from the sub- clavian; at first, it mounts vertically upon the anterior scalenus, and having reached the level of the fifth vertebra, it makes a sudden turn in- wards ; it then passes transversely behind the common carotid, following the same course as the omo-hyoideus, and arrives at the inferior and external part of the thyroid gland, after having given off the ascending cervical artery and a few twigs. It then divides into two large branches, which ])ass behind the gland and anastomose with the superior thyroid arteries, and the inferior of the opposite side. * Operalion of It/ing the inferior Thyroid Artery.—Tlio in- teguments must be divided along the anterior edge of the sterno- cleido-mastoid muscle; and push to one .side the cellulo-apo- neurotic sheath which encloses the carotid; we then seek for the inferior thyroid artery, a little under and behind the omo- liyoid muscle. In applying the ligature, the two principal nerves which pass before and behind the vessel must not be included ; consequently, we must vary the method according to the position of the parts. If the nervous trunks are very close to the trachea, the needle must be passed from below upwards, and from within outwards; if those nerves are nearer the carotid, we should pass it in the opposite direction.
