The Peruvian and Kanaka have all the three lines in small proportion to the parietal 
depth, and the Hindoo skulls only differ in having a greater frontal depth. The Greek 
skulls and the Maori resemble these only in the short occipito-parietal depth, but have 
the forehead high and the occipital tuberosity moderately projecting. The single 
Chinese skull is deficient in frontal depth, but is full behind. The Esquimaux have all 
three lines well developed as compared with the parietal depth, which means that the 
parietal depth is deficient, a consequence of the flatness of the parietal part of the arch 
formerly alluded to. The French and Scotch skulls have the occipital, occipito-parietal, 
and frontal depths all moderately developed in proportion to the parietal depth ; the 
German, Kafir, and Australian skulls differ from them in having the frontal depth com- 
paratively great, and the Negroes in having the occipital depth greater, while the Irish 
have not only the occipital, but likewise the occipito-parietal depth great. Probably 
the most important part of these results is that which relates to the Peruvians, Kanaka, 
Hindoos, and Greeks, as it bears on what will fall to be advanced in considering the 
proportion of height to length. 
Height (column 72). — The height of a skull is estimated by different writers in various 
ways. Von Baee measures it from the plane of the foramen magnum to the most distant 
point of the vertex*. Mr. Huxley has preferred a line with definite termini, and
