    bath in the copper oven. I kept it there, gently stirring ] with the needle occasionally, until thoroughly dissolved. When perfectly cool, I filled the glass, up to the mark made with the file, with cold water, and stirred with the needle until thoroughly incorporated. The needle was weighed when clean and dry, before and after stirring the liquid ; the difference in weight was unappreciable. It is surely unne- ' cessary to demonstrate that this solution is the first [ centesimal of Hahnemann, made with loo grains instead of i grain, and that every minim of the loo contains i grain of ' sugar, the scale being 99 upon i,oriinioo. I place this glass of syrup in my “ Centesimal Fluxion Potentizer,” and I set the latter in action with my hand, slowly and deliberately, as I i always do with the first five attenuations—and the more so must I do so in this experiment, as 1 am manipulating a ' viscid fluid, which is certain to adhere to the glass in more ' than double the quantity it would if it were water or spirit | and water. The glass is upset, and returns for a fresh | charge of 99 or 100 minims, bringing back of the first | attenuation what adheres to the inside of the glass. Let us I take stock of it. The contents of the glass being evaporated to perfect dryness in the sand-bath in the copper oven and allowed to cool, weighed exactly 117 grains. Deduct weight of glass 112 „ Amount of sugar left in the glass 5 grains. Considering the viscidity of the “ mother tincture,” and the quantity of substance operated upon, the result compares favourably with the Fluxion-process of Fincke, where, at the first off-go, we got the same amount of sugar out of 10 grains operated upon. If it had not been for the syrupy character of the mother-liquor, I should certainly have had I grain instead of five grains. Let us try again !
