The study of the structure of the normal thyroid gland has been strangely neglected. So long as the morphologic character of the goitrous gland was just one more thing to quarrel about, this lack of knowledge of the normal gland was not a serious matter. Now that the relation of the goitrous gland to the heart has been abundantly demonstrated in the clinic, knowledge of the anatomy of the nongoitrous gland becomes an imperative necessity. The question is whether or not a nongoitrous gland may so degenerate as to affect the heart as a goitrous gland does. In order to answer this question it will be necessary to examine a large number of thyroid glands of nongoitrous persons.
Goiter is a clinical term. This becomes important in the morphologic study when one attempts to compare the nongoitrous and the goitrous gland. Even in the laboratory it is often a question
