It is worthy of note that criminals begin to use tobacco at an early age. Thus among a population which normally begins to smoke before the age of thirty only in the proportion of 14 per cent. (and the insane 7.2 per cent.), 22 per cent. of criminals smoke before the age of thirty, and nearly all (279 out of 300 males and 32 out of 32 women) before entering prison. Venturi[51] found tobacco used by 14.3 per cent. of normal men, 1.5 of normal women; 45.8 of criminal men, 15.9 of criminal women. Marambat[52] concluded that the love of tobacco was the first passion that rooted itself in the youthful criminal. Out of 603 juvenile delinquents, between the ages of eight and fifteen, 51 per cent. had acquired the custom of using tobacco before their detention. Lombroso notes that the sensibility of criminals to the weather appears to be greater than that of the ordinary population. He found it in 29 out of 112. There were 9 who became quarrelsome shortly before storms, and one of these remarked that his companions always foretold bad weather when he sought to quarrel. Dostoieffsky observed that quarrels and disturbances were particularly common among the convicts in the spring. What is true of the Russian prisoners in Siberia seems also to be true of American prisoners at New York. From some tables given by Dr. Wey of Elmira it appears that marks for bad conduct are specially numerous in the spring, and also, to some extent, in the autumn. _Vaso-motor Sensibility._--Inability to blush has always been considered the accompaniment of crime and shamelessness. Blushing is also very rare among idiots and savages; the Spaniards used to say of the South American Indians: “How can one trust men who do not know how to blush?” From the investigations of Amadei, Tonnini, and Bergesio, it appears that if we compare lunatics and criminals, twice as many of the latter are incapable of blushing. Pasini, in his examinations of women, noted blushing in 21 per cent. of murderers, 20 per cent. of poisoners, 18 per cent. of infanticides, and only 10 per cent. of thieves. It was not at the mention of their offences that they blushed, but when questioned concerning their menstrual functions. Out of 130 criminal women examined by Salsotto, 50 blushed when spoken to concerning their offences. Dr. Andronico of Messina communicated to Lombroso some interesting, though too general, observations concerning the prostitutes and young female criminals in prison under his charge. “Among the inscribed prostitutes,” he remarks, “none blushed when questioned concerning their occupation. I have seen some of them blush when reproached for unnatural practices. I have noted that female homicides narrate their deeds ingenuously and without blushing; those who have poisoned their husbands blush, but partially. Among female prisoners condemned for theft, blushing shows itself first on the ears, then on the face; those who are condemned for excitation to prostitution do not blush.”
