Lime, in the state of marble, owes its insolubility in water and its mildness to an acid of the lowest order which is combined with it; when heated to red heat the marble allows this acid to escape as a gas. During this process the marble, as burned lime, has received (besides the latent heat) another substance into its composition, which sub- stance, unknown to chemistry, gives to it its caustic property as well as its solubility in the water, whereby we obtain lime-water. This sub- stance, though itself not an acid, gives to it its caustic virtue, and by adding a fluid acid (which will endure fire), which then combines with the lime by its closer affinity, the watery caustic (Hydras Caustici?) is separated by distillation.

Take a piece of freshly burned lime of about two pounds, dip this piece into a vessel of distilled water for about one minute, then lay it in a dry dish, in which it will soon turn into powder with the develop- ment of much heat and is peculiar odor, called lime-vapor. Of this fine powder take two ounces and mix with it in a (warmed) porcelain tritu- rating bowl a solution of two ounces of bisulphate of potash, which has been heated to red heat and melted, cooled again and then pul- verized and dissolved in two ounces of boiling hot water. This thickish mixture is put into a small glass retort; to which the helm is attached with wet bladder; into the tube of the helm is inserted the receiver half submerged in water; the retort is warmed by the gradual approach of a charcoal fire below and all the fluid is then distilled over by applying the suitable heat. The distilled fluid will be about an ounce and a half of water clearness, containing in concentrated form the substance mentioned above, i.e., Causticum; if smells like the lye of caustic pot- ash. On the back part of the tongue the caustic tastes very astringent, and in the throat burning; it freezes only in a lower degree of cold than water, and it hastens the putrefaction of animal substances immersed in it. When Muriate of Baryta is added, the causticum shows no signs of sulphuric acid, and on adding oxalate of ammonia it shows no traces of lime.1

 

2. Hahnemann’s description of trituration:

 



In this preparation, peculiar to Homeopathy, we take one grain in powder of any of the substances treated of in the six volumes of Ma- teria Medica Pura, and especially those of the antipsoric substances following below, i.e., of silica, carbonate of baryta, carbonate of lime, carbonate of soda and sal ammoniac, carbonate of magnesia, veg- etable charcoal, animal charcoal graphites, sulphur, crude antimony,
