IV. The blood-corpuscle considered in its different phases of development in the animal series. Memoir I.—Vertebrata

Abstract

The mode in which I purpose to treat this part of my subject, is to trace the blood-corpuscle in its different phases of development in the vertebrate series, from the lower to the higher classes. I commence therefore with the blood-corpuscle of the Skate, taken as an example of the lowest class.
