Lamarck, while affirming the verbal proposition that animals form a single series, was forced by his vast acquaintance with the details of zoology to limit the assertion to such a series as may be formed out of the abstractions constituted by the common characters of each group.'
Latreille,2 rightly estimating the value of these differences, though he was not an original worker in the field of vertebrate zoology, proposed to separate Brongniart's Batrachia from the class of Reptilia proper, as a group of equal value, for which he retained the Linnaean name of Amphibia.
Scientific zoology really started in the 16th century with the awakening of the new spirit of observation and exploration, but for a long time ran a separate course uninfluenced by the progress of the medical studies of anatomy and physiology.
The zoology of Australia and Tasmania presents a very conspicuous point of difference from that of other regions of the globe, in the prevalence of non-placental mammalia.
The eastern parts of Australia are very much richer both in their botany and in their zoology than any of the other parts.
NEMATODA, in zoology, a group of worms. The name Nematoda (Gr.
Maas in Results of In its arrangement the muscular tissue the "Albatross " Expedition, forms two s stems: the one composed Museum of Comparative Y P Zoology, Cambridge, Masse, of striated fibres arranged circularly, that U.S.A. is to say, concentrically round the central FIG.
Naturalists who deal specially with museum collections have been compelled, it is true, for other reasons to attach an increasing importance to what is called the type specimen, but they find that this insistence on the individual, although invaluable from the point of view of recording species, is unsatisfactory from the point of view of scientific zoology; and propositions for the amelioration of this condition of affairs range from a refusal of Linnaean nomenclature in such cases, to the institution of a division between master species for such species as have been properly revised by the comparative morphologist, and provisional species for such species as have been provisionally registered by those working at collections.
Almost every side of zoology has contributed to the theory of evolution, but of special importance are the facts and theories associated with the names of Gregor Mendel, A.
In zoology, the mollusca are divided into cephalous and acephalous (Acephala), according as they have or have not an organized part of their anatomy as the seat of the brain and special senses.
Lankester, Introductory Chapter in A Treatise on Zoology; E.
The great advance in modern zoology as regards the classification of the Hexapoda lies in the treatment of a heterogeneous assembly which formed Linnaeus's order Neuroptera.
This foundation was laid by the joint labours of Francis Willughby (1635-1672) and John Ray (1628-1705), for it is impossible to separate their share of work in natural history more than to say that, while the former more especially devoted himself to zoology, botany was the favourite pursuit of the latter.
Impressed by the belief that verbosity was the bane of science, he carried terseness to an extreme which frequently created obscurity, and this in no branch of zoology more than in that which relates to birds.
3 A greater undertaking was Pennant's Arctic Zoology, published in 1785, with a supplement in 1787.
In 1830 John Edward Gray commenced the Illustrations of Indian Zoology, a series of plates of vertebrated animals, G w but mostly of birds, from drawings, it is believed by dlcke..
In 1828 James Wilson (author of the article Ornithology in the 7th and Wilson 8th editions of the present work) began, under the title of Illustrations of Zoology, the publication of a series of his own drawings (which he did not, however, himself engrave) with corresponding letterpress.
Fleming, Fleming already the author of a harmless and extremely orthodox Philosophy of Zoology, pointed out in 1829 in the Quarterly Review (xli.
This seems to have been his last attempt; for, two years later, his Bibliography of Zoology shows little trace of his favourite theory, though nothing he had uttered in its support was retracted.
Gray, first in the Appendix to Dieffenbach's Travels in New Zealand (2843) and then in the ornithological portion of the Zoology of the Voyage of H.M.S.
Shaw's Zoology of New Holland (4to, 1794) added those of a few more, as did J.
Blanchard published some Recherches sur les caracteres osteo- logiques des oiseaux appliquees a la classification naturelle de ces animaux, strongly urging the superiority of such characters over those drawn from the bill or feet, which, he remarks, though they may have sometimes given correct notions, have mostly led to mistakes, and, if observations of habits and food have sometimes afforded happy results, they have often been deceptive; so that, should more be wanted than to draw up a mere inventory of creation or trace the distinctive outline of each species, zoology without anatomy would remain a barren study.
3 Here there is no need to enter into details of the history of evolution; but there was possibly no branch of zoology in which so many of the best informed and consequently the most advanced of its workers sooner accepted the principles of evolution than ornithology, and of course the effect upon its study was very marked.
Unfortunately none of these, however, can be compared for singularity with Archaeopteryx or with some American fossil forms next to be noticed, for their particular It is true that from the time of Buffon, though he scorned any regular classification, geographical distribution had been occasionally held to have something to do with systematic arrangement; but the way in which the two were related was never clearly put forth, though people who could read between the lines might have guessed the secret from Darwin's Journal of Researches, as well as from his introduction to the Zoology of the " Beagle" Voyage.
As the number of species of insects is believed to exceed that of all other animals taken together, it is no wonder that their study should form a special division of zoology with a distinctive name.
His only unfortunate contribution to entomology - indeed to zoology generally - was his theory of pre-formation, which taught the presence within the egg of a perfectly formed but miniature adult.
Few branches of zoology have been more valuable as a meetingground for professional and amateur naturalists than entomology, and not seldom has the amateur - as in the case of Westwood - developed into a professor.
After the publication of C. Darwin's Origin of Species (1859) a fresh impetus was given to entomology as to all branches of zoology, and it became generally recognized that insects form a group convenient and hopeful for the elucidation of certain problems of animal evolution.
A kindly old pedant, Fulcher interlards his history with much discourse on geography, zoology and sacred history.
Havundersiigelser, Serie Hydrografi (Copenhagen 1904-20), contain important papers; the publications of the university of California (Zoology) deal with the work of the Scripps Inst.
Indeed, the historical and present importance of this aspect or branch of zoological science is so great that the name " zoology " has until recently been associated entirely with it, to the exclusion of the study of minute anatomical structure and function which have been distinguished as anatomy and physiology.
The principal contributors to the " Transactions " of this section of the academy were--for anatomy and physiology, Coloman Balogh, Eugene Jendrassik, Joseph Lenhossek and Lewis Thanhoffer; for zoology, John Frivaldszky, John Kriesch and Theodore Margo; for botany, Frederick Hazslinszky, Lewis Juranyi and Julius Klein; for mineralogy and geology, Joseph Szabo, Max Hantken, Joseph Krenner, Anthony Koch and Charles Hoffman; for physics, Baron Lorando Eotviis, Coloman Szily and Joseph Sztoczek; for chemistry, Charles Than and Vincent Wartha; for meteorology, Guido Schenzl.
