There is, however, no doubt that the various races, when carefully compared and measured, differ much from each other,—as in the texture of the hair, the relative proportions of all parts of the body (2. A vast number of measurements of Whites, Blacks, and Indians, are given in the ‘Investigations in the Military and Anthropolog. Statistics of American Soldiers,’ by B.A. Gould, 1869, pp. 298-358; ‘On the capacity of the lungs,’ p. 471. See also the numerous and valuable tables, by Dr. Weisbach, from the observations of Dr. Scherzer and Dr. Schwarz, in the ‘Reise der Novara: Anthropolog. Theil,’ 1867.), the capacity of the lungs, the form and capacity of the skull, and even in the convolutions of the brain. (3. See, for instance, Mr. Marshall’s account of the brain of a Bushwoman, in ‘Philosophical Transactions,’ 1864, p. 519.) But it would be an endless task to specify the numerous points of difference. The races differ also in constitution, in acclimatisation and in liability to certain diseases. Their mental characteristics are likewise very distinct; chiefly as it would appear in their emotional, but partly in their intellectual faculties. Every one who has had the opportunity of comparison, must have been struck with the contrast between the taciturn, even morose, aborigines of S. America and the light-hearted, talkative negroes. There is a nearly similar contrast between the Malays and the Papuans (4. Wallace, ‘The Malay Archipelago,’ vol. ii. 1869, p. 178.), who live under the same physical conditions, and are separated from each other only by a narrow space of sea.
