In the following pages are included all official drugs, also some few others that are frequently employed by prescribers.

In the case of the frequently used agents the effort has been made to give complete information as to how to employ them to meet the conditions for which they are commonly used. No effort has been made to show the use in each disease, but only to give the practical information and illustrations that will enable the busy practitioner to apply theory, and, sitting at the bedside, write prescriptions for the well-known medicinal agents in a way that will reflect credit on himself and serve the best interest of the patient.

Drugs that are seldom prescribed are not discussed in detail.

While this is not intended as a work on therapeutics, the prescriptions given are selected from many thousands and are, with few exceptions, formulae that are of tried therapeutic merit. The therapeutic indications in the index are arranged to convert this part of the work into a formulary of considerable scope.

Effort has been made to have each prescription correct from every standpoint, and so given that it can be transcribed on a prescription blank, letter for letter, and sent to the drug-store-a document above criticism.
