✦ Synopsis

A new method for identifying the emulsion type of surfactant is introduced--volume balance value, that is, the ratio of hydrophilic group and hydrophobic group volumes in surfactant. The radius used in the volume for the VB value comes from the Pauling radius based on quantum chemistry. The result shows that the surfactant is an o/w emulsifying agent and water-soluble when the VB is more than 1, and is a w/o emulsifying agent and oil-soluble when the VB is less than 1. The VB value possesses additivity.

Pharmacy, Education, and Sections in Pharmacy**At the request of Dr. Charles Rice, in the latter part of the last century (1894), I wrote the first volume of a treatise entitled β€œA Study in Pharmacy” This work, comprising two hundred and twelve pages, was put into type and presented in fascicles, privately, to a limited circle of friends likely to be interested in the problems embraced therein. Otherwise, publication was not ventured. May I not hope that after its twenty-five years of slumber, this fragment, seemingly yet pertinent, may not prove a cumberer to pharmaceutical literature?
