Note 234 — Chapter VI
Hugh J. C. Beavan translation
[Dr. Waitz, in his Introduction to Anthropology (translated and edited by J. F. Collingwood), gives an explanation concerning the colouring matter in the Negro, which is very curious, but with which, however, he does not agree; viz., “that in hot climates the amount of oxygen inspired is insufficient to change the carbon into carbonic acid, and that the unconsumed carbon is deposited in the pigment-cells of the skin.... It is, however, difficult to admit that the browning of the skin in our climate in summer is produced by the same causes as the black colour of the Negro, and that it would only require a greater intensity and a longer duration to become so entirely.” Part. I, sect. i, p. 35.—Editor.]
