The independent practitioner : a monthly journal, devoted to medicine, surgery, obstetrics, dentistry, pathology and popular science . the tissue of the teethby acids, which are for the greater part generated in the mouth byfermentation. The object of the investigations described in thisand the following papers is to determine this ferment, and the con-ditions essential to its action. I shall seek in what follows to presentno views which are not the legitimate and necessary results of rigidand exact experiment, and I shall give in detail a description ofeach series of experiments, in order that every one may have anopportunity to judge of the accuracy of the work and the justice ofthe conclusions drawn from it. It is, nevertheless, with some hesitancy that I venture to presentbefore the dental profession the results of my last six months labor,having learned by experience the almost endless number of agentswhich combine to vitiate such a series of experiments as that whichI am about to offer, and the exceeding great care which is necessaryin excluding or eliminating all irrelevant factors. 58 Original If, therefore, I have been guilty of any oversight, or failed to takeall possible precautions to guard against error, I hope that some onewill kindly show me where I have gone astray, and put me in theright course again. The larger apparatus necessary for these experiments are : 1. A large double-walled incubator, with gas regulator for main-taining any desired constant temperature. 2. A Koch sterilizer. 3. A damp chamber. (See Fig. 1.) 4. A drying oven for sterilizing instru-ments, glass vessels, etc., at a temperatureof one hundred and fifty degrees Centi-grade. 5. A good micros^p^, with either wateror oil immersion. It is not necessary to mention the smallerinstruments, glass vessels, etc., etc., northe apparatus necessary for making afig. l. chemical analysis of the products of the fermentation ; these are sufficiently familiar to every one.
