the skull being thrown, as it were, back, or developed only posteriorly ; 

 so that the foramen magnum occupies a much more forward situation than 

 237 in skulls moderately depressed, 



forming a striking contrast, in this 

 particular, with the Negro cranium : 

 the forehead retreats at once from 

 the orbital margin ; the orbits are 

 large and quadrate ; the nasal 

 bones are flat ; the alveolar arch 

 projects; the chin is well formed; 

 and the posterior angle of the 

 lower jaw is acute : from the middle 

 skuii of THicacan. o f the occipital condyle to the al- 



veoli of the front incisors, the distance is four inches and one-eighth ; 

 from the same spot to the posterior extent of the skull, it is five inches 

 and a half (see fig. 237). 



The same museum contains two skulls of Peruvians, from Pachacamac, 

 or the Temple of the Sun, in the valley of Rimac, together with a dried 

 mummy, sitting in a crouched attitude, with the chin resting on the knees, 

 and the hands placed on each side of the face. These remains are, pro- 

 bably, to be attributed to the period of the Incas dynasty. 



The skulls are deserving of notice, for the inequality of their develop- 

 ment, or the want of harmony be- 

 tween their sides. In one (fig. 238), 

 the forehead is retreating and sub- 

 compressed, but the vertex is some- 

 what elevated ; the general contour 

 is round, but not regularly ; the pa- 

 rietal bones bulge, but one differs in 

 shape from the other ; and the tem- 

 poral and the occipital bones of one 

 side are not equally balanced by the 

 same bones of the other ; the breadth 

 of the frontal bone is considerable ; 

 the occiput is compressed; the distance from the middle of the 

 occipital condyle to the edge of the alveoli of the front incisor teeth 

 being four inches and a half ; the occipital development beyond the same 

 point, only three inches ; the nasal bones are small ; the malar bones are 

 broken. In all essentials, the second skull resembles the preceding one, but 

 is much less elevated, vertically ; the vertex viewed from the front being, 

 indeed, in the form of a slightly-depressed arch ; the malar bones are 

 large, and the external orbitar angles prominent ; the alveoli are some- 

 what projecting ; the general contour is round and deep. The skull
