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.
Apart from his special discoveries in the anatomy of plants and animals, and his descriptions of new species, the great merit of Linnaeus was his introduction of a method of enumeration and classification which may be said to have created systematic zoology and botany in their present form, and establishes his name for ever as the great organizer, the man who recognized a great practical want in the use of language and supplied it.
Waagen's law of mutation, or the appearance of new parts or organs so gradually that they can be perceived only by following them through successive geologic time stages, appears to be directly contradictory to the saltation principle; it is certainly one of the most firmly established principles of palaeontology, and it constitutes the contribution par excellence of this branch of zoology to the law of evolution, since it is obvious that it could not possibly have been deduced from comparison of living animals but only through the long perspective gained by comparison of animals succeeding each other in time.
Crepusculum, twilight), of or belonging to the twilight, hence indistinct or glimmering; in zoology the word is used of animals that appear before sunrise or nightfall.
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.
In this same leisurely manner I studied zoology and botany.
His true greatness can only be estimated by a consideration of the fact that he was a great teacher not only of human and comparative anatomy and zoology but also of physiology, and that nearly all the most distinguished German zoologists and physiologists of the period 1850 to 1870 were his pupils and acknowledged his leadership. The most striking feature about Johann Miller's work, apart from the comprehensiveness of his point of view, in which he added to the anatomical and morphological ideas of Cuvier a consideration of physiology, embryology and microscopic structure, was the extraordinary accuracy, facility and completeness of his recorded observations.
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.
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.
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.
