Tosetti was of honest extraction, his grandparents and parents having died at an advanced age (between sixty and ninety) without having manifested nervous anomalies, vices, or crimes. Tosetti himself, although fond of drinking, was rarely, if ever, intoxicated, and was an individual of quiet, peaceful aspect with a benevolent smile and serenity of look and countenance. His hair had become grey at an early age, and he was devoid of any degenerate characteristics except excessive maxillary development. [Height 5 feet, 7 inches (1.70 m.); weight, 158 lbs. (72 kilogrammes); cranial capacity, 93 inches (1531 c.c.); cephalic index, 84 (brachycephaly; characteristic of the Piedmontese); tactile sensibility, 3 mm. left, 2.5 mm. right; general sensibility, 83 right, 78 left; sensibility to pain, 55 right, 45 left. The sensibility was, therefore, almost normal without any trace of left-handedness. Analysis of urine--absence of earthy phosphates common to born criminals. Tendinous reflex action feeble, few cutaneous reflexes, no tremors. The field of vision was not much reduced but manifested a few peculiarities, due no doubt to the abuse of alcohol.] Psychologically, Tosetti appeared to be a man of average or perhaps slightly less than average intelligence. He was quiet, very respectful, not to say servile, entirely devoid of impulsiveness of any form, and averse to quarrels, on which account he was rather despised by his companions. His natural affections were normal, and he was a good son and brother; he was excessively timid and disconcerted by the slightest reproof from his employer. He was rather fond of wine, though not of liquors. His sexual instincts he had lost very early, a fact which caused his companions to indulge in many jokes at his expense. His stinginess bordered on avarice, and he had never changed his trade. During his trial he showed no resentment against anyone, not even the police and warders, of whom he said on one occasion, "They have treated me like a son." The examination proved beyond a doubt that Tosetti was not a born criminal, and was incapable of committing the action of which he was suspected--the murder of a child for purely bestial pleasure. To obtain stronger proof, my father adopted the plethysmograph and found a slight diminution of the pulse when Tosetti was set to do a sum; when, however, skulls and portraits of children covered with wounds were placed before him, the line registered showed no sudden variation, not even at the sight of the little victim's photograph. The results of the foregoing examination proved conclusively that Tosetti was innocent of a crime which can only be committed by sadists, idiots, and the most degenerate types of madmen, like Vacher and Verzeni and all bestial criminals, who have reached the summit of criminality and unite in their persons the greatest number of morbid physical and psychic characteristics.
