Scope of the Work
Buffon planned his "Natural History" on an encyclopaedic scale. His point of view was unique. Natural history in its widest sense, he tells us, embraces every object in the visible universe. The obvious divisions of the subject, therefore, are, first, the earth, the air, and the water; then the animals—quadrupeds, birds, fishes, and so on—inhabiting each of these "elements," to use the phrase of his day. Now, Buffon argued, if man were required to give some account of the animals by which he was surrounded, of course he would begin with those with which he was most familiar, as the horse, the dog, the cow. From these he would proceed to the creatures with which he was less familiar, and finally deal—through the medium of travellers' tales and other sources of information—with the denizens of field, forest and flood in foreign lands. In similar fashion he would consider the plants, minerals, and other products of Nature, in addition to recounting the marvels revealed to him by astronomy.
Whatever its defects on the scientific side, Buffon's plan was simplicity itself, and was adopted largely, if not entirely, in consequence of his contempt—real or affected—for the systematic method of the illustrious Linnæus. Having charted his course, the rest was plain sailing. He starts with the physical globe, discussing the formation of the planets, the features of the earth—mountains, rivers, seas, lakes, tides, currents, winds, volcanoes, earthquakes, islands, and so forth—and the effects of the encroachment and retreat of the ocean.
Animate nature next concerns him. After comparing animals, plants and minerals, he proceeds to study man literally from the cradle to the grave, garnishing the narrative with those incursions into the domains of psychology, physiology and hygiene, which, his detractors insinuated, rendered his work specially attractive and popular.
I.—The Four-Footed Animals
Such questions occupied the first three volumes, and the ground was now cleared for the celebrated treatise on Quadrupeds, which filled no fewer than twelve volumes, published at various dates from 1753 (vol. iv.) to 1767 (vol. xv., containing the New World monkeys, indexes, and the like). Buffon's modus operandi saved him from capital blunders. Though inordinately vain—"I know but five great geniuses," he once said; "Newton, Bacon, Leibniz, Montesquieu, and myself"—he was quite conscious of his own limitations, and had the common-sense to entrust to Daubenton the description of the anatomy and other technical matters as to which his own knowledge was comparatively defective. He reserved to himself what may be called the "literary" aspect of his theme, recording the place of each animal in history, and relating its habits with such gusto as his ornate and grandiose style permitted.
After a preliminary dissertation on the nature of animals, Buffon plunges into an account of those that have been domesticated or tamed. Preference of place is given to the horse, and his method of treatment is curiously anticipatory of modern lines. Beginning with some notice of the horse in history, he goes on to describe its appearance and habits and the varieties of the genus, ending (by the hand of Daubenton) with an account of its structure and physiology. As evidence of the pains he took to collect authority for his statements, it is of interest to mention that he illustrates the running powers of the English horse by citing the instance of Thornhill, the postmaster of Stilton, who, in 1745, wagered he would ride the distance from Stilton to London thrice in fifteen consecutive hours. Setting out from Stilton, and using eight different horses, he accomplished his task in 3 hours 51 minutes. In the return journey he used six horses, and took 3 hours 52 minutes. For the third race he confined his choice of horses to those he had already ridden, and, selecting seven, achieved the distance in 3 hours 49 minutes. He performed the undertaking in 11 hours and 32 minutes. "I doubt," comments Buffon, "whether in the Olympic Games there was ever witnessed such rapid racing as that displayed by Mr. Thornhill."
Justice having been done to it, the horse gives place to the ass, ox, sheep, goat, pig, dog, and cat, with which he closes the account of the domesticated animals, to which three volumes are allotted. It is noteworthy that Buffon frequently, if not always, gives the synonyms of the animals' names in other languages, and usually supports his textual statements by footnote references to his authorities.
When he comes to the Carnivores—"les animaux nuisibles"—the defects of Buffon's higgledy-piggledy plan are almost ludicrously evident, for flesh-eaters, fruit-eaters, insect-eaters, and gnawers rub shoulders with colossal indifference. Doubtless, however, this is to us all the more conspicuous, because use and wont have made readers of the present day acquainted with the advantages of classification, which it is but fair to recognise has been elaborated and perfected since Buffon's time.
As his gigantic task progressed, Buffon's difficulties increased. At the beginning of vol. xii. (1764) he intimates that, with a view to break the monotony of a narrative in which uniformity is an unavoidable feature, he will in future, from time to time, interrupt the general description by discourses on Nature and its effects on a grand scale. This will, he naively adds, enable him to resume "with renewed courage" his account of details the investigation of which demands "the calmest patience, and affords no scope for genius."
