Stage, and a young adult of 250 mm., the brain of which is figured entire in figure A. This spec imen has not yet been sectioned, but as it is adult in all characters except size, it is doubtful whether it will throw any more light on the development of the gland. It has, in this specimen, the characteristic shape. But is slightly smaller in proportion to the brain than in older individuals.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
