Samuel Hahnemann Letter

[Christian Friedrich] Samuel Hahnemann (MD 1779, University of Erlangen) was born in 1755 in Meissen, Saxony. He is considered the founder of homeopathy—the treatment of a disease with small doses of a remedy that, in healthy persons, produce symptoms similar to those of the disease.

This letter, written in German by Dr. Hahnemann, discusses the homeopathic treatment of cholera by spirits of camphor and the prevention of it by watered copper. The letter includes neither the name nor the address of the addressee.
