In the arrangement of the formulas in this volume the plan of numbering them has, as in former editions, been adopted. This method saves frequent repetition of the formulas, makes them convenient for reference, and at the same time more particularly designates one from another, as there are in many instances several preparations bearing the same name yet differing in composition.

Fenner's Formulary is a comprehensive handbook originally designed for druggists of his day but now recognized as enabling the layperson to create their own pharmacy, as it were, using basic tool and scientific guidelines that are as meaningful to day as they were when the text was written in the late 19th century.

This guide starts with an introduction that includes weight and other systems of measurement, heat measures, calculating the gravity of liquid and that of solids. Part 1 is titled "Drugs and Medicinal Substances" and goes into 3 sections: Mineral Drugs, Vegetable Drugs and Animal Drugs.

Part 2 is titled "Working Processes" and goes into a wide variation of preparations, ranging from dialysis, distillation, filtration, infusions, decoctions and more.

This is the type of handbook that would be a useful addition to any self sufficiency collection. Who wouldn't want to learn to make their own medicine?
