The ABC Manual of Materia Medica and Therapeutics by G. Hardy Clarke
The ABC Manual of Materia Medica and Therapeutics by George Hardy Clarke. Originally published in 1901. Clark was Professor of Materia Medica at Hahnemann Homeopathy College, Chicago. The writer has ventured to assume that the simplification of the subject gained by referring only to toxic effects of drugs, their therapeutic uses in non-toxic doses, the relation of the two as indicated by numerals, and the elimination of controversial matter, is sufficient warrant for offering this manual to students and to his fellow practitioners.
He has to make acknowledgment for material that has been freely drawn from the writings of Bartholow, Hempel, Hughes, Ringer, Still, Wood and others.
