examination of the form and ftruflure of the tulks, has declared they were eflentially different from thofe of the elephant;
becaufe another* anatomift, equally cele- brated, has declared, on a like examination, that they are precifely the fame.
Between two fuch authorities I will fup- pofe this circumftance equivocal. But, i. The ikeleton of the mammoth «^for fo the incognitum has been called) befpeaks an animal of five or fix times the cubit vo- lume of the elephant, as Moof. de BufFon has admitted. 2. The grinders are five times as large, are fquare, and the grinding furface ftudded with four or five rows of blunt points: whereas thofe of the elephant are broad and thin, and their grinding furface flat. 3. I have never heard an inftance, and fuppofe there has been none, of the grinder of an elephant being found in America. 4. From the known temperature and conftitution of the elephant he could never have exifted in thofe regions where the remains of the mammoth have been found. The ele- * D'Aubenton.
phant is a native only of the torrid zone and its vicinities; if, with the affiftance of warm apartments and warm clothing, he has been preferved in life in the temperate climates of Europe, it has only been for a fmall portion of what would have been his natural period, and no inftance of his multiplication in them has ever been known. But no bones of the m.ammoth, as I have before obferved, have been ever found further fouth than the falines of the Holfton, and they have been found as far north as the Ardic circle. Thofe, therefore, who are of opinion that the elephant and mammoth are the fame, muft believe, i. That the elephant known to us can exift and multiply in the frozen zone; or, 2. That an eternal fire may once have warmed thofe regions, and fince abandoned them, of which, however, the globe exhibits no unequivocal indications;
or, 3. That the obliquity of the ecliptic, when thefe elephants lived, was fo great as to include within the tropics all thofe regions in which the
