As the erotomaniac falls in love with an ideal person, and imagines himself loved by one who has never even seen him, so they can see no aspect of the case but their own; and the lawyers and judges who do not support them become enemies on whom they concentrate the fiercest hatred, and whom they look on as the cause of every misfortune that may befall them. It is not rare to find them constituting themselves judges in their own cause, pronouncing sentence, on their own responsibility, on their adversaries, and sometimes going the length of executing the same. A certain B----, from whom the parish priest had taken a field by a perfectly legal and regular contract, took it into his head that he had the right to assault all the priests of his village, “because,” he said, “Catholicism is in opposition to the Government.” For the same reason he tried to burn down the church; and all this, after a series of lawsuits and proclamations, very just, it may be conceded, in principle, but certainly not in application. These persons have, too, a similar kind of handwriting, with very much lengthened letters; and they likewise abuse the alphabet. Their theme, however, is confined to their immediate circle, and they show more violence in dealing with it; they only touch by rebound, as it were, on social and religious questions. Yet the personal litigations of many of these suitors are mixed up with political differences; and this is the kind from which most danger is to be expected in our day. These are usually individuals whose scant education and extreme poverty do not allow them to air their ideas in print, so that they have to relieve their feelings by deeds of violence. Such was Sandon, who caused such annoyance to Napoleon and to Billault, and was a genuine political mattoid; such, too, were Cordigliani, Passanante, Mangione, and Guiteau. Krafft-Ebing speaks of a man who had founded a Club of the Oppressed, for the assistance of those who could get no justice from the Courts, and forwarded its rules to the king. _Mattoids of Genius._--Not only is there an imperceptible gradation between sane and insane, between madmen and mattoids, but also between these last (who are the very negation of genius) and men of real genius. So much so, that among my collection there are certain individuals I find a difficulty in classifying. Such, for instance, is Bosisio, of Lodi.
