important means of making the differentiation between the various forms of goiter.

Prognosis.—In parenchymatous goiter most cases recover. The glands grow smaller until of normal size or near it, and any general symptoms disappear. However, in cases where the glands are enormously enlarged and symptoms of cretinism and myxedema are present the prognosis is not favorable. A recurrence of this form of goiter, while rare, is always probable.

Treatment.—lodin medication both externally and internally has proved to be of great value. Some remarkable results have been obtained in the rapidity and degree of reduction after its use. For internal administration it has been definitely proved that small doses give the best results. The dose should be regulated somewhat according to the age and size of the animal. One-fourth grain, 0.016 of potassium iodid for puppies, or 0.05-0.08 for older animals, given once daily, has given the best results. When given in large doses there is danger of too rapid depletion of the body and paralysis of the heart. These small doses should be continued daily for one to three weeks. For external application colorless tincture of iodin may be applied. Where staining the hair does not matter the regular tincture should be employed. An application can be made daily, or every second day. Thyroid extract (0.15 daily) has been used with excellent results. Surgical interference has not proved successful in relieving this form of goiter. Complete unilateral thyroidectomy might be tried in case one gland is enormously enlarged and the other nearly normal. The operation is performed under general anesthesia and strict antiseptic precautions. The gland is dissected out carefully and multiple ligation of the pedicle is necessary so that the tissue will not retract and allow the ligature to slip off. The gland is then removed about ^ inch from the ligature and the wound packed with antiseptic gauze for a few days. The ligature is then removed cautiously and the wound covered with an antiseptic dusting power. It is very important that the wound be kept free from infection during the first few days, and the ligature kept in position to avoid fatal hemorrhage.
