Excerpt from A Laboratory Guide in Materia Medica and Pharmacy The subject of Materia Medica is difficult to present more on account of deciding what to exclude than what to include. It is granted that there are many things in Materia Medica impossible and useless to memorize. On the other hand, students should have an opportunity to examine and become more or less familiar with the synonyms, origin and physical characteristics of the most used drugs, and laboratory work is believed to be the best means of learn ing these things. The grouping of the drugs for studying Materia Medica is ar ranged to correspond with the work in Pharmacology but other wise is purely arbitrary.
