Tap- ping, injection of astringents, simple incision, and the seton are obsolete. Ligation of the thy- roid arteries is rarely performed as a curative measure. The superior and inferior thyroids of one side have been tied in some cases; all four thyroids in other cases. Jaboulay exothyropcxy. In this operation the gland is dislocated from its bed, brought out of the vvfound, and left exposed, in hope that it will atrophy.

Diviidon. of the isthmus is occasionally practised to relieve dyspnea. The operation some- times succeeds, but often fails. Extirpation of one-half or two-thirds of the gland is a very successful operation. Removal of the entire gland will be followed by operative myxedema. Removal or injury of the parathyroids causes tetany. In extirpating a lobe of the thyroid by the method until recently in vogue, great care must be taken to avoid tearing the capsules, as if this happens the gland tissue bleeds profusely. The thyroid arteries should be ligated on the diseased side before an attempt is made to remove the mass, and in ligating the inferior thyroid the position of the recurrent laryngeal nerve must be borne in mind, so as not to include it in the ligature. In order to preserve the parathyroids from injury, C. H. Mayo recommends that after the vessels entering and leaving the thyroid have been double clamped and divided, the entire lobe should be elevated, the capsule split along the side of the gland and pushed back with gauze, and the gland lifted and removed without disturbing the posterior portion of the capsule. As pointed out before, the posterior portion of the capsule is so thick and strong that it is easier to leave it in situ than to bring it out of the wound with the gland. A cystic or solid tumor of the thyroid may be removed by iiiiraglandular enucleation. If opera-
