Not seen by writer. Dr. W. M. Wheeler, of Harvard University, has kindly sent me the following note from p. 285. “‘It is to ethology therefore that the fourth part of this work is devoted, to which belongs the study of the relations of organisms within the family and the society in the aggregate and in the community.’ In a volume of the same work, page xx, St. Hilaire gives his program and speaks of the general facts belonging to ethological laws. These are defined as ‘relating to the instincts, habits and more generally to the external vital manifestations of organisms.’” About the preceding Dr. Wheeler remarks: “You see this covers precisely the field which was a few years later called ‘ecology’ by Haeckel. Apparently the part of the work in which St. Hilaire wished to give a detailed account of the ethological phenomena of animals was not published. Only three volumes of the work exist. He died November 10, 1861, without having completed the work.” Thus ethology has priority over ecology, but to my mind this fact carries no special weight, particularly since the word has become current in botany. To use a different name for the same subject or process in botany and zoölogy is as undesirable as to use a different term for heredity in plants and in animals. LANKESTER, E. R. 1889. Article “Zoölogy.” Ency. Britannica, 9th ed. Amer. Reprint. Vol. XXIV, pp. 842, 856. Lankester defines “Bionomics.--The lore of the farmer, gardener, sportsman, fancier, and field naturalist, including thremmatology, or the science of breeding, and the allied teleology, or science of organic adaptations: exemplified by the patriarch Jacob, the poet Vergil, Sprengel, Kirby and Spence, Wallace, and Darwin.... Buffon (1707-1788) alone among the greater writers of the three past centuries emphasized that view of living things which we call ‘bionomics.’ Buffon deliberately opposed himself to the mere exposition of the structural resemblances and differences of animals, and, disregarding classification, devoted his treatise on natural history to a consideration of the habits of animals and their adaptations to their surroundings, whilst a special volume was devoted by him to the subject of reproduction.... Buffon is the only prominent writer who can be accorded historic rank in this study.” As I have access to but few of Buffon’s writings, I quote the above. Bionomics is seen not to be synonymous with ecology, as defined by most students, although it includes much that is ecological. The chaotic and unorganized “lore of the farmer” has no unifying or guiding principles, and although it contains many facts, from which a science may be built, to call it science seems undesirable.
