There is a generally recognised tendency to the pointed (oxycephalic) or sugar-loaf form of head. Though this form is probably, as Benedikt points out, an effort at compensation, it is an effort that testifies to defective organisation. The opposite defect of low or flat-roofed skull is also found among criminals, and is characteristic of degeneration. Lauvergne, in his old book on criminals, has a vivid and picturesque sketch of a variety of this kind of head, which he called the satanic type, and which he found among many of the worst criminals: “Such are the heads which painters throw into their pictures, and call ‘heads of the other world.’ I have recognised them in mediæval pictures, and in all the museums in which the products of early art are preserved. You will see them on old cathedrals, in which devils play a part, or wherever the artist has received some diabolical inspiration, as in the Campo Santo at Pisa. One cannot, indeed, better represent the genius of evil, Satan, the fallen angel, than by giving him such a head.... Behind the frontal bones the head seems to have been tied with a band to compress it around and to force the swelling of the hemispheres upwards and backwards. It is the head vulgarly called sugar-loaf. When it is complete, that is to say, when it presents a prominent base supporting an inclined pyramid, more or less truncated, this head announces the monstrous alliance of the most eminent faculty of man, genius, with the most pronounced impulses to rape, murder, and theft.” Benedikt regards the bilateral elevation of the sagittal suture as, though rare, “significant of profound perversity of brain function.” He also regards disproportionate development of the occipital part of the skull as a characteristic mark of degeneration.[17] It appears that the posterior half of the skull varies much more in different individuals than the anterior half. The orbital capacity has been noted by Lombroso and others to be frequently larger than normal (as among birds of prey and some savages), especially among thieves. There is marked exaggeration of the orbital arches and frontal sinuses which may be related, at all events in the cases of individuals living in the country, with energy of the respiratory system. Receding foreheads, very commonly observed among criminals, have always been regarded as evidence of low mental and moral organisation, not without reason, though it must be remembered, as Ten-Kate and Benedikt point out, that the breadth, vaulting, and general size of the head must be taken into consideration. Many men of marked intellectual power have had receding foreheads.
