In another case, a girl of sixteen, the daughter of an Italian general, complained to her father that a certain lieutenant, her neighbour at table, had used indecent language to her. Shortly afterwards, a shower of anonymous letters troubled the peace of the household--declarations of love addressed to the girl's mother and threats to the daughter. It was discovered that the girl herself was the writer of all these letters.
Anonymous letter-writing is so common among hysterical persons, that it may be considered a pathognomonical characteristic. The handwriting is of a peculiar character, or rather it shows a peculiar tendency to vary from excessive size to extreme smallness, a characteristic we have noticed in epileptics.
_Delirium._ Hysterical, like epileptic, subjects often suffer from melancholia or monomaniacal delirium. Indeed, according to Morel, this symptom is more frequent when the other morbid phenomena are absent.
Psychic hysteria, like epilepsy, may exist unaccompanied by the characteristic hysterical attack, and then, as is the case with epilepsy, it is most dangerous to society.
In conclusion, although up to the present, medical men have been disposed to consider hysteria as a disease distinct from epilepsy, careful study of this malady inclined my father to class it as a variation of epilepsy, prevalent among women, who in this disease, as in many others, manifest an attenuated form.
We have seen how, owing to disease, alcoholism and epilepsy, physically and psychically degenerate individuals make their appearance in a community of normal persons. But a large proportion of the crimes committed cannot be attributed to lunatics, epileptics, or the morally insane, nor do all criminals show that aggregate of atavistic and morbid characters,--the cruelty and bestial insensibility of the savage, the impulsiveness of the epileptic, the licentiousness, delusions, and impetuosity of the madman,--which we find united in the born criminal.
According to statistics obtained by my father, the share contributed to the sum total of criminality by this latter type is only 33%, which appears to be a magic figure for the criminal, since it corresponds to the percentage of the histological anomaly discovered by Roncoroni and to that of all important anomalies, including those of the field of vision. But besides this percentage of born criminals, doomed even before birth to a career of crime, whom all educational efforts fail to redeem and who therefore should be segregated at once; besides the epileptic, hysterical, and inebriate lunatics and those insane from alcoholisation, of whom we have already spoken, there remain a number of criminals, amounting to a full half, in whom the virus is, so to speak, attenuated, who, although they are epileptoids, suffer from a milder form of the disease, so that without some adequate cause (_causa criminis_) criminality is not manifested. The inhibitory centres are somewhat obtuse, but not altogether absent, so that a healthy environment, careful training, habits of industry, the inculcation of moral and humane sentiments may prevent these individuals from yielding to dishonest impulses, provided always that no special temptation to sin comes in their path.
