Lecithoblast und Angioblast der Wirbelthiere

Abstract

THIS memoir is the latest and largest of a series, published by the author in the Transactions of the Saxon Academy of Science. Its title indicates that it treats of histogenetic studies in those parts of the developing germ which are concerned in the formation of the blood-vessels and blood, and in the elaboration and assimilation of the yolk-mass. The table of contents at the close reveals a very much wider sphere of research than that suggested by the title. It is, indeed, a treatise on histogenesis. Prof. His himself describes it as a sort of histological testament. Like some other documents of the like name, it contains very varied provisions. Almost all the phenomena witnessed in the early development of the embryo are treated of at greater or less length, the first blood-vessels and blood and the changes undergone by the yolk and its components receiving special attention. The work is full of detailed observations, and these are described at the hand of a complex terminology.
