(To prepare it, we take one pound of bones calcined white and broken into small pieces, place them in a porcelain jar, and pour over them one pound of the strongest sulphuric acid. The mixture is to be stirred with a glass rod several times during twenty-four hours, then well mixed and diluted with two pounds of good brandy, and the whole tied up in linen bag and pressed out between two smooth boards loaded with weights. What remains in the bag may be again diluted with two pounds of brandy, and the expressed fluid added to the first quantity. The whole is to be allowed to stand for two days, so that the cloudiness may settle down. The clear fluid is now to be decanted off, evaporated in a porcelain dish over the fire, and melted at a red heat. The melted phosphoric acid should be as clear as crystal, and while still warm it is to be broken into small fragments and preserved in a wellcorked bottle, because when exposed to the sir it soon completely deliquesces into a thickish fluid as clear as water.)
A grain of this crystalline acid id dissolved in 100 drops of a mixture of nine parts of water with one part of alcohol (the alcohol being added in order to make it drop easily). The solution is succussed twice (with two strokes of the arm). A drop of this is again succussed with 100 drops of alcohol by means of succussion with two strokes of the arm. This is 1. And the process is repeated up to the trillion-fold dilution (III). A sugar globule the size of a poppy seed, and moistened with this trillion-fold dilution, is administered for a homoeopathic dose.
The following remarkable, pure, artificial morbid symptoms produced by phosphoric acid on the healthy body indicate of them selves the natural morbid states in which it is specifically curative by reason of homoeopathic similarity.
Every dose acts for more than two weeks in chronic diseases.
The over violent action of phosphoric acid is diminished by camphor.

5. Heat in the head, which often caused vertigo, even when sitting; when writing he must often nod involuntarily; objects seemed to turn round; the table seemed as if falling; when he clutched hold of it in walking, and when he looked on ground when standing, he was like to fall forwards, and must make a step forwards in order to keep himself erect.
