Aggiungi al carrelloSoft cover. Condizione: Very Good. Thomas Henry Huxley. Huxley's First Paper (aged 24). "On the anatomy and the affinities of the family of the medusae" extracted from the Philosophical Transactions of the Royal Society of London, Richard and John E. Taylor, vol 139, 1849. This is the entire article, pp 413-34, with three plates…. This copy has been cleaned up, with the spine nicely mended with Japan tape, and the whole being sewn-in to new wrappers of high-quality paper. VERY GOOD. Nice copy. [++] "Perhaps no class of animals has been so much investigated with so little satisfactory and comprehensive result as the family of the Medusae, under which name I include here the Meduoe, Monostomaoe and Rhizostomioe; and this, not for the want of patience or ability on the part of the observers (the names of Ehrenberg, Milne-Edwards, and De Blainville, are sufficient guarantees for the excellence of their observations), but rather because they have contented themselves with stating matters of detail concerning particular genera and species, instead of giving broad and general views of the whole class, considered as organized upon a given type, and inquiring into its relations with other families. 2. It is my intention to endeavour to supply this want in the present paper with what success the reader must judge. I am fully aware of the difficulty of the task, and of my own incompetency to treat it as might be wished; but, on the other hand, I may perhaps plead that in the course of a cruise of some months along the east coast of Australia and in Bass s Strait I have enjoyed peculiar opportunities for investigations of this kind, and that the study of other families hitherto but imperfectly known, has done much towards suggesting a clue in unravelling many complexities, at first sight not very intelligible."--from the first paragraph of the Huxley paper. [++]"Already in his first work "On the Anatomy and the Affinities of the Medusæ,' 1849, he directed attention to the very important point, that the body of these animals is constructed of two cell layers of the Ectoderm and the Endoderm and that these, physiologically and morphologically, may be compared to the two germinal layers of the higher animals."--Clark University website "While Huxley was on the Rattlesnake in 1849, the Royal Society of London published his paper On the Anatomy and the Affinities of the Family of the Medusae. In this paper, Huxley added to the comparative embryological discoveries of Karl Ernst von Baer, professor at the University of Königsberg in Königsberg, Prussia who had asserted that vertebrates from different species appeared similar as they passed through stages of embryological development. Adult jellyfish, Huxley found, were made of two cell layers. When Huxley compared the tissue layers of these adult marine organisms to the germ layers of vertebrate embryos, he noticed that the vertebrate embryos exhibited the same double-tissued structure in the early stages of development as the adult jellyfish. By drawing parallels between the body plan of adult jellyfish and the body plan of embryonic vertebrates, Huxley inferred a connection between organismal development, called ontogeny, and historical relationships between taxa, called phylogeny. The relationship between ontogeny and phylogeny would be adopted and elaborated over the following years by Charles Darwin in London, and by Ernst Haeckel, the Professor of Comparative Anatomy at the University of Jena in Jena, Germany."--Embryo Encyclopedia Project (ASU) (Huxley). 714,3.
