INTRODUCTION.^ 
ORIGIN AND SCOPE OF BULLETIN. 
The United States Pharmacopoeia is the official standard for the 
U. S. Public Health and Marine-Hospital Service. Drugs purchased 
for its hospitals and relief stations must confomi to the Pharmaco- 
poeia! requirements. A circular letter, calling the attention of the 
medical officers and pharmacists of the Service to the many and impor- 
tant changes in the revised edition, was at first contemplated. It was 
believed that such a letter would aid these officials in their study of 
the revised Pharmacopoeia and facilitate the early adoption of the new 
names and new preparations. Later, with the approval of the Board 
of Trustees of the Pharmacopceial Convention, it was decided to pub- 
lish this information in the form of a bulletin. It is believed that 
such a bulletin will help the practitioner to a better understanding of 
the significance of some of the innovations. Being written for physi- 
cians, only such changes are discussed in this bulletin as are of interest 
and use to them, such, for example, as changes in the strength of 
preparations, changes in name, the additions, etc. For changes relat- 
ing to methods of preparation, of tests for identity, purity, etc., the 
reader is referred to the Pharmacopeia itself. 
«The authors are greatly indebted to Dr. Daniel Base, of the Division of Pharma- 
cology, for valuable assistance rendered in the preparation of this bulletin.
