Excerpt from The Art of Compounding, a Text Book for Students and a Reference Book for Pharmacists, at the Prescription Counter
While the immediate reason for a revision of this work was to bring the book into accord with the ninth decennial revision of the United States Pharmacop?ia, yet the principal changes have been made on extra-pharmacop?ial matter. Most of the subjects have been enlarged by a selection of matter that is likely to be of use at the prescription-counter.
A chapter on Tablets has been added, which treats of the manufacture of compressed and triturate tablets. The use of tablet machines is increasing in connection with prescriptions, and the simplifying of the principles governing tablet-making will be welcomed by many dispensers.
Occasional demands for a sterilized preparation, or for the sterilization of implements or articles for surgical or medicinal use, is the warrant for the added chapter on Sterilization and Disinfection. No attempt has been made to cover the whole field in this subject, but only to treat it so that any demands which the pharmacist may meet can be intelligently fulfilled. For valued advice in this chapter I am indebted to Dr. H. J. Perry, Instructor in Bacteriology at the Harvard Medical School, and also at the Massachusetts College of Pharmacy, who kindly made final corrections in the manuscript.
The subject of Emulsions has been largely rewritten, and includes the latest theories of emulsification and also improved methods and formul? for commercial emulsions.
Capsules are more fully treated in the chapter on Powders, and many additions have been made to the chapter on Incompatibilities.
The author would welcome any suggestions or criticisms on any of the subjects treated, from any source.
