Nearly 40,000 species of animals and plants have been added to the Systema Naturae by paleontologic research. This is a living population equivalent to that of a new continent in mere number; equivalent to that of a new hemisphere, if we take into account the small population of insects as yet found fossil, and the large proportion and peculiar organization of many of the Vertebrata.

Linnaeus was a naturalist in this wide sense, and his 'Systema Naturae' was a work upon natural history, in the broadest acceptation of the term; in it, that great methodising spirit embodied all that was known in his time of the distinctive characters of minerals, animals, and plants.

I shall not detain the Reader with my Observations in this aerial Journey; Gallileus, who by his Writings gives me room to believe he had, before me, visited this Planet, whatever were his Reasons for not owning it, having left nothing, which is not mentioned in his Systema Mundi.

It must be recollected that Linnaeus included silex, as well as limestone, under the name of "calx," and that he would probably have arranged Diatoms among animals, as part of "chaos." Ehrenberg quotes another even more pithy passage, which I have not been able to find in any edition of the Systema accessible to me: "Sic lapides ab animalibus, nec vice versa.

It remains for me to ask your forgiveness for intruding upon your time and attention with the half-century-old real or fancied memories of a nonagenarian as contributions to the history of the most notable event in the annals of Biology that had followed the appearance in 1735 of the "Systema Naturæ" of Linnæus. Following Sir J. Hooker, the President, referring to Prof.

If we accept the view taken by Wyville Thomson and his colleagues that the red clay is the residuum left after the calcareous matter of the Globigerinoe ooze has been dissolved away then clay is as much a product of life as limestone, and all known derivatives of clay may have formed part of animal bodies.

But the enormous stimulus which Linnaeus gave to the investigation of nature soon rendered it impossible that any one man should write another 'Systema Naturae, and extremely difficult for any one to become even a naturalist such as Linnaeus was.

Linnæus was a naturalist in this wide sense, and his "Systema Naturæ" was a work upon natural history, in the broadest acceptation of the term; in it, that great methodizing spirit embodied all that was known in his time of the distinctive characters of minerals, animals, and plants.

Isaac Casaubon, whose name in the sixteenth century shed lustre on the learned circles of Geneva, Montpellier, Paris, London and Oxford, began as professor of Greek, at the age of twenty-two; and Heinsius, his Leyden contemporary, at eighteen. It was at the age of twenty-eight, that Linnaeus first published his Systema Naturae.
