Hahnemann thought this may be the reason that bark is the curative agent for this fever, and he extended his theory to account for the action of drugs in other diseases. In order to do this satisfactorily, he selected a certain number of healthy people to whom he gave a drug and carefully noted its action. This was called proving the drug.
A STRIKING NATRUM MURIATICUM CASE. I can never forget my first patient-a little, thin old maid about thirty-five years of age who did not weigh over one hundred pounds. Her skin was the colour of the brown paper in which the grocers of that time wrapped up lard, etc. I looked at her hands and the finger-nails were bluish and her hands were cold. She complained of obstinate constipation, headache, great prostration and pain in the region of the liver and she was always cold.
