Derkum (“Journ. Nervous and Mental Disease,” 1892, xvii.) gives an anatomical description of a (Chinese brain, the seventh which has been carefully examined. In this the features characteristic of the other brains were again noted, namely, unusual degree of convolution, disposition to anastomosis in the perpendicular and horizontal directions, and marked obliquity of the orbital surfaces of the frontal lobes (with the last-mentioned may probably be associated the peculiar position of the eyes in the Chinese). Blending of the central and Sylvian fissures is said to be a frequent feature of such brains. For other details see the original paper.
