A Manual of Organic Materia Medica and Pharmacognosy

The present volume is in a slight degree a revision of a work written by the author in 1879 entitled Organic Materia Medica and Pharmacal Botany. This work has been out of print a number of years and until recently the author has had no time to rewrite it in such a manner as seemed necessary to bring it up to the present standard; it has also been deemed advisable to change completely the model of the former work. The task now accomplished presents not so much a revision as a new treatise.
