V. The blood-corpuscle considered in its different phases of development in the animal series. Memoir II.—Invertebrata

Abstract

The invertebrate animals, of which I am here about to consider the blood-corpuscle in its different phases of development, are some of the more readily procurable examples of the divisions Annulosa and Mollusca. The order in which I purpose to proceed is from the higher to the lower classes of each division, an order the contrary of that adopted in the case of the Vertebrata.
