Packs, of course, must be regulated in accordance with the vital strength of the patient, as indicated by the physician; for in the course of the excretion of morbid matter through the pores, under the influence of the packs, a certain proportion of accompanying healthy substance is necessarily exuded simultaneously, with a slightly weakening tendency. This however can be promptly and effectively replaced by proper alimentation, or food selection in accordance with the Dech-Manna Diet System already particularized. One other matter it is advisable to deal with in advance and that is the _Nature of the Vinegar to be employed for Packs_. It must be borne in mind that for this purpose an absolutely pure natural product should be obtained. I recommend, in the first place a genuine _Apple Cider Vinegar_; for apples not alone contain the pure acetic acid but also some five or six other fruit acids which are so beneficial for the purpose of keeping the blood at normal temperature and normal fluidity, and contain also a considerable amount of the essentials known under the head of vitamines. As a secondary alternative I would recommend _Wine Vinegar_ for the same purpose. The manufacturers vinegar product--_Acetic acid, should never the used_ as it contains, very frequently, harmful ingredients. It should never be forgotten that the substances used for the purpose of packs, and thus absorbed into the system, become a part of the blood and therefore cannot be too pure. The reader will doubtless observe from the foregoing demonstration that the Dechmann System of Therapy differs materially from the science of the Old-School of Medicine in that it is not based upon evanescent theories of hairsplitting philosophy but upon the solid basis of cold-blooded fact. Why then, the reader will inquire, should so wonderful and at the same time _simple, inexpensive and easily applied remedy_ be treated by "the faculty" with an affectation of indulgent toleration, ridicule or "damning with faint praise." To this riddle there are two solutions--neither of them very creditable to those concerned. On the one hand, only crass ignorance of some of the most important facts of physiology and physiological chemistry could account for it. And, it must be borne in mind that in the course of the prolific verbosity of pontificated dogma which has graced the scroll of medical science, whole libraries have been written--and ably written, too--by skillful pens for the sole purpose of covering the simple nudity of the agnostic position of science--the dreaded, confidence-shattering admission: "I don't know." Failing this solution there is, unfortunately, but one alternative and that a singularly distasteful one to entertain; namely, to attribute the unpopularity of this splendid gift of Nature to unprofessional considerations on the part of an apothecary-loving profession.
