The preparation used by Hahnemann in his provings, and which ought, therefore, to be preferred to all others, was made as follows: Place a thick piece of ox-hide leather on red-hot coals, and leave it there so long as it burns with a flame. As soon, however, as the flame ceases, lift off the red-hot mass, and extinguish it by pressing between two flat stones. This will, of course, contain several substances besides carbon, which, however, cannot interfere with its action, seeing that one ox-hide is not likely to differ materially from another.
