III. Contributions to the minute anatomy of the thyroid gland of the dog

The minute structure of the thyroid gland generally, and of its lymphatics in particular, are subjects still but imperfectly understood. With the view of elucidating the latter, the following research was made on the thyroid gland of the dog. The research was carried out under the direction of Dr. Klein. On injecting the lymphatics of this organ with Berlin blue, by the method of puncture, they present the following characters:—
