Others were weak and sickly in childhood; such were Demosthenes, Bacon, Descartes, Newton, Locke, Adam Smith, Boyle, Pope, Flaxman, Nelson, Haller, Körner, Pascal, Wren, Alfieri, Renan. Ségur wrote of Voltaire that his leanness recalled his labours, and that his slight bent body was only a thin, transparent veil, through which one seemed to see his soul and genius. Lamennais was “a small, almost imperceptible man, or rather a flame chased from one point of the room to the other by the breath of his own restlessness.”[14] _Physiognomy._--Mind, a celebrated painter of cats, had a cretin-like physiognomy. So also had Socrates, Skoda, Rembrandt, Dostoieffsky, Magliabecchi, Pope, Carlyle, Darwin, and, among modern Italians, Schiaparelli, who holds so high a rank in mathematics. _Cranium and Brain._--Lesions of the head and brain are very frequent among men of genius. The celebrated Australian novelist, Marcus Clarke, when a child, received a blow from a horse’s hoof which crushed his skull.[15] The same is told of Vico, Gratry, Clement VI., Malebranche, and Cornelius, hence called _a Lapide_. The last three are said to have acquired their genius as a result of the accident, having been unintelligent before. Mention should also be made of the parietal fracture in Fusinieri’s skull;[16] of the cranial asymmetry of Pericles, who was on this account surnamed Squill-head (σκινοκἑφαλος) by the Greek comic writers[17]; of Romagnosi, of Bichat, of Kant,[18] of Chenevix,[19] of Dante, who presented an abnormal development of the left parietal bone, and two osteomata on the frontal bone; the plagiocephaly of Brunacci and of Machiavelli; the [Illustration: Figs. 1-3. Kant’s Skull. “ 4. Volta’s Skull. Figs. 5-6. Fusinieri’s Skull. “ 7-8. Foscolo’s Skull.] extreme prognathism of Foscolo (68°) and his low cephalic-spinal and cephalic-orbital index;[20] the ultra-dolichocephaly of Fusinieri (index 74), contrasting with the ultra-brachycephaly which is characteristic of the Venetians (82 to 84); the Neanderthaloid skull of Robert Bruce;[21] of Kay Lye,[22] of San Marsay (index 69), and the ultra-dolichocephaly of O’Connell (index 73), which contrasts with the mesocephaly of the Irish; the median occipital fossa of Scarpa;[23] the transverse occipital suture of Kant, his ultra-brachycephaly (88·5), platycephaly (index of height 71·1), the disproportion between the superior portion of his occipital bone, more developed by half, and the inferior or cerebellar portion. It is the same with the smallness of the frontal arch compared to the parietal.
