That series of terrific events by which our quiet city and university in the northeastern quarter of Germany were convulsed during the year 1816, has in itself, and considered merely as a blind movement of human tiger-passion ranging unchained among men, something too memorable to be forgotten or left without its own separate record; but the moral lesson impressed by these events is yet more memorable, and deserves the deep attention of coming generations in their struggle after human improvement, not merely in its own limited field of interest directly awakened, but in all analogous fields of interest; as in fact already, and more than once, in connection with these very events, this lesson has obtained the effectual attention of Christian kings and princes assembled in congress. No tragedy, indeed, among all the sad ones by which the charities of the human heart or of the fireside have ever been outraged, can better merit a separate chapter in the private history of German manners or social life than this unparalleled case. And, on the other hand, no one can put in a better claim to be the historian than myself. I was at the time, and still am, a professor in that city and university which had the melancholy distinction of being its theater. I knew familiarly all the parties who were concerned in it, either as sufferers or as agents. I was present from first to last, and watched the whole course of the mysterious storm which fell upon our devoted city in a strength like that of a West Indian hurricane, and which did seriously threaten at one time to depopulate our university, through the dark suspicions which settled upon its members, and the natural reaction of generous indignation in repelling them; while the city in its more stationary and native classes would very soon have manifested THEIR awful sense of things, of the hideous insecurity for life, and of the unfathomable dangers which had undermined their hearths below their very feet, by sacrificing, whenever circumstances allowed them, their houses and beautiful gardens in exchange for days uncursed by panic, and nights unpolluted by blood. Nothing, I can take upon myself to assert, was left undone of all that human foresight could suggest, or human ingenuity could accomplish. But observe the melancholy result: the more certain did these arrangements strike people as remedies for the evil, so much the more effectually did they aid the terror, but, above all, the awe, the sense of mystery, when ten cases of total extermination, applied to separate households, had occurred, in every one of which these precautionary aids had failed to yield the slightest assistance. The horror, the perfect frenzy of fear, which seized upon the town after that experience, baffles all attempt at description. Had these various contrivances failed merely in some human and intelligible way, as by bringing the aid too tardily-- still, in such cases, though the danger would no less have been
