Almost all the medical men of those times were in possession of arcana which they employed either in all or at least in most diseases, in a very unprofessional manner, and the efficacy of which the sweet delusions of self-interest did not permit them to call in question. The severe metallic remedies of the Spagyric school, which was then in its infancy, were not yet introduced, but there were not wanting strong heating medicines from the ancient stores of the empyrics, which almost universally obtained the preference over the mild potions and syrups of the Arabians. Hellwetter sold a powder of unknown composition, and a number of distilled waters, which Dr. Magnus Hundt, of Leipzig, notices with much approbation. The pamphlet of this physician is in every respect of the most ordinary kind; it affords no proof that the author had any sound comprehension of the disease, and belongs to that class of low medical compositions which, in times of danger, is so easily derided by the public, and so much diminishes the estimation of the profession, to the material injury of the general welfare. It must not, however, be supposed that the people, who in such times of commotion often confound together the good and the bad, listened everywhere so readily to these pamphleteers. The composition of one Dr. Klump, at Ueberlingen, who, on the breaking out of the disease, attacked his patients with theriac and all kinds of heating plague powders, excited great derision[653], and it cannot be denied that the people had on their side, at least occasionally, the advantage of sound sense, as opposed to the endless prescriptions of the physicians, and it is gratifying to observe how this sound sense, which doubtless was guided by respectable medical men, operated in a great many towns to the advantage of those affected.
