INTRODUCTION. 
The following research is a continuation of that previously communicated to the 
Society on the “ Minute Anatomy of the Thyroid GJand of the Dog,” and published in 
the Philosophical Transactions for 1876 (Vol. 166, Part II.). It is based on a 
histological examination of the thyroid gland in the following vertebrate animals :— 
I. Mammalia. Dog, Cat, Horse, Babbit, Ox, Sheep, Seal. 
II. Aves. Pigeon, Fowl, Book. 
III. Reptilia. Tortoise. 
IV. Amphibia. Frog. 
V. Pisces. Skate, Conger Eel. 
(Altogether the glands of more than sixty animals have been examined in this 
research.) 
My examination of the human thyroid gland is unfortunately not sufficiently com-
