Among normal men about two or three anatomical stigmataare often found 5 among lunatics, criminals, abortive types of para-noia, and primary forms of neurasthenia, the number is much greater. The accompanying table will be of help in making the investiga-tions relating to the cranium (page 43). To understand it, it is necessary to describe the skull landmarks,and to give briefly the classification and terms used by anthropolo-gists and alienists in describing the dimensions and shape of the skull. Dimensions and Shape of Skull — General Classification.—Anthropologists make a general classification of skulls into:. Fig. 19. — M, j3, T, The Triangle for Ascertaining the Empirical Greatest Height (Benedict). The dolichocephalic, in which the antero-posterior diameter isto the transverse as 100 is to 75 or less; the brachycephalic, inwhich the length is to the breadth as 100 is to 80 or more; themesocephalic, in which the length is to the breadth as 100 is to 75to 80. The physiological limits of variation in the ratio of lengthto breadth are from 100 to 70 to 100 to 90. The dimensions andshape of the skull vary with age, sex, individual, race, and withcertain pathological conditions and artificial deformities. In gen-eral, however, the variations in the shape and size of the skulls of DIAGNOSIS AND METHODS OF EXAMINATION. 43 s M& HO « wtit> x «!W M MO oH n ■s| >- 0 jj a = - d — 0 c3 » O • C- *1 *p 5* h$2 p IE 0 H J - J J .;- ffi ^m D 1 OS- SPSP, =-3— f = a*j-,S^ ai| .■sgS
