_Rule 8._--OBJECTIONABLE NAMES.--Proprietary names for medicinal articles will be recognized only when the Council shall deem the use of such exclusive names to be in the interest of public welfare. Names which are misleading or which suggest diseases, pathologic conditions or therapeutic indications will not be recognized (the provision against therapeutically suggestive names does not apply to serums, vaccines and antitoxins, or to foods). In the case of pharmaceutical preparations or mixtures, the name must be so framed as to indicate the most potent ingredients. _Rule 9._--PATENTED PRODUCTS AND PROTECTED NAMES.--If the article is patented--either process or product, or both--the number of such patent or patents must be furnished to the Council. Furthermore, if the name of an article is registered, or the label copyrighted, the registration (trademark) number and a copy of the protected label should be furnished the Council. In case of registration in foreign countries, the name under which the article is registered should be supplied. _Rule 10._--UNSCIENTIFIC AND USELESS ARTICLES.--No article will be accepted or retained which, because of its unscientific composition, is useless or inimical to the best interests of the public or of the medical profession. Explanatory Comments on the Rules INTRODUCTION.--The Council on Pharmacy and Chemistry was established in February, 1905, by the American Medical Association, primarily for the purpose of gathering and disseminating such information as will protect the medical profession in the prescribing of proprietary medicinal articles. In pursuance of this object, the Council examines the articles on the market as to their compliance with definite rules designed to prevent fraud, undesirable secrecy and the abuses which arise from advertising directly or indirectly to the laity. Such articles as appear to conform to the rules are accepted; and their essential features are described in the annual publication of the Council, New and Nonofficial Remedies, if they come within the scope of this book. These descriptions are based in part on investigations made by, or under, the direction of the Council, but in part also on evidence or information supplied by the manufacturer or his agents. Such interested statements are examined critically, and are admitted only if they appear to be in conformity with the evidence. It is, however, manifestly impossible for the Council to investigate the composition of every complex pharmaceutical mixture, or to check thoroughly every therapeutic claim; it can give only an unbiased judgment on the available evidence. Criticisms and corrections of the descriptions which may aid in the revision of the matter will be appreciated. The Council judges an article entirely by the facts in evidence at the time of its admission. Previous noncompliance with the rules (short of _intentional_ fraud) does not prevent the favorable
