from that of their Asiatic ancestors, from whom it i ascertained beyond reasonable doubt, that they hav derived their origin; the same ingenuity, I presume will be competent to account for the remaining dif ferences which, for want of the like reflection, seem at present, to embarrass him. STRICTURES, &c. LORD KAIMS, in a preliminary discourse to his sketches of the history of man, has undertaken to combat the principle of the unity of the human species. As Mr. White has proposed to assemble against it all the objections which can be derived from the science of Anatomy, Lord Kaims has endeavoured to collect, and present to us in one united view, those which arise from the history of man, and from such speculative principles, or such moral causes, as are supposed chiefly to influence the state and condition of human nature, as it relates to the particular subject of his discourse. The reputation of this writer stands so high in the literary world as a philosopher, that it is justly to be presumed; he has advanced whatever can be most plausibly urged from these sources against the opinion which he opposes. If his objections, therefore, can be fairly set aside, or successfully answered, the refutation of such an antagonist will probably be regarded as bringing no inconsiderable addition of strength to the preceeding argument. I hope, then, to be able to shew that with regard to many facts on which his lordship relies, in this disquisition, he has been egregiously misinformed; and that almost the whole of his reasoning, even where his facts have been better ascertained, is inconclusive, or concludes only against his own principle. His dissertation he commences with a speculative argument drawn from his own ideas of propriety, and the wisdom of providence.-"Certain it is," says he, "that all men, more than all animals, are not equally fitted for every climate.

The power of climate to affect the figure and general appearance of the person, which his lordship, in this paragraph acknowledges, when he informs us that, in consequence of changing their habitations mankind often degenerate, is the very principle on which, united with the influence of diet |
