Excerpt from Practical Materia Medica: And Prescription Writing With Illustrations In the Second Edition the effort has been made to bring the text up-to-date, particularly with reference to the Pharmacopc ial changes. Some new drugs have been added, both official and otherwise; some have been retained that are now not official, and, following the Pharmacop ia, many have been dropped, with a sigh of relief. Much new matter has been added that it is hoped will prove of value. Acknowledgments are made of many valuable criticisms and suggestions, particularly from Dr. John Taylor Halsey, Professor of Pharmacology and Clinical Medicine, in Tulane University.
