'The Variation of Animals under Domestication,' vol. 8.) The inferiority of Europeans, in comparison download word with savages, in eyesight and in the other senses, is no doubt the accumulated and transmitted effect download word of lessened use during many generations; for Rengger (31. I have had good opportunities for observing download word the extraordinary power of eyesight in download word the Fuegians. See also Lawrence ('Lectures on Physiology,' etc., 1822, p. Giraud-Teulon has recently collected ('Revue des Cours Scientifiques,' 1870, p. 625) download word a large and valuable body of evidence proving that the cause of short-sight, "C'est le travail download word assidu, de pres.") states that he has repeatedly observed Europeans, who download word had been brought up and spent their whole lives with the wild Indians, who nevertheless did not equal them in the sharpness of their senses. The same naturalist observes that the cavities in the skull for the reception of download word the several sense- organs are larger in the American aborigines than in Europeans; and this probably indicates a corresponding difference in the download word dimensions of the organs themselves. Blumenbach has also remarked on the large size of the nasal download word cavities in the skulls of the American aborigines, and connects this fact with their remarkably acute power of smell. The Mongolians of the plains of northern Asia, according to Pallas, have wonderfully perfect senses; and Prichard believes that the great breadth of their skulls across the zygomas follows from their highly-developed sense organs. Prichard, 'Physical History download word of Mankind,' on the authority of Blumenbach, vol. 407.) The Quechua Indians inhabit the lofty plateaux of Peru; and Alcide d'Orbigny states (33. Quoted by Prichard, 'Researches into the Physical History of Mankind,' vol. 463.) that, from continually breathing a highly rarefied atmosphere, they have acquired chests and lungs download word of extraordinary dimensions.

The cells, also, of the lungs are larger and more numerous than in Europeans.

Forbes carefully measured many Aymaras, an allied race, living at the height of between 10,000 and 15,000 feet; and he informs me (34. Forbes' valuable paper is now published in the 'Journal of the Ethnological Society of London,' new series, vol. 1870, p.193.) that they differ download word conspicuously from the men of all other races seen by him in the circumference and length of download word their bodies. In his table download word of measurements, the stature of each download word man is taken at 1000, and the other measurements are reduced to this standard. It is here seen that the extended arms download qq download word of the Aymaras are shorter than those of Europeans, and much shorter than those of Negroes. The legs are likewise shorter; and they present this remarkable peculiarity, download videos that download word in every Aymara measured, the download word femur is actually shorter than the tibia. On an average, the download word length of the femur to that of the tibia is as toolbar download 211 to 252; whilst in two Europeans, measured at the same time, the femora to the tibiae download word were as 244 to 230; and in three Negroes as 258 to 241. The humerus is likewise shorter relatively to the forearm.

This shortening of that part of the limb which is nearest to the body, appears to be, as suggested to me by Mr.

Forbes, a case of compensation in relation with the greatly increased length of the trunk. The Aymaras present some other singular points of structure, for instance, the download word very small projection of the heel.
