PREFACE TO THE SECOND EDITION.
The text has been revised; the views of physiologists, therapeutists, oculists, and surgeons generally have been brought up to date; those of chemists of the constitution of Cocaine have been epitomized, and pharmaceutical and chemical notes have been added on the modes of dispensing and testing the purity of Hydrochlorate of Cocaine. Being printed in larger type than the first edition, I trust it may be more acceptable to general medical readers.
