From the above findings we conclude that Tyree’s antiseptic powder is a mixture of boric acid and dried zinc sulphate and antiseptic bodies, such as menthol, salicylic acid and carbolic acid, eucalyptol, etc. From this it can be readily seen that the label which is supposed to set forth the composition of Tyree’s antiseptic powder is not in accord with the facts. The powder does not contain either borate of sodium or alum, and the presence of glycerin could not be established. The antiseptic agents, exclusive of the boric acid, are present only in small amounts. The report of another analyst concludes as follows: It evidently contains less than the amount stated of the principles of thyme, eucalyptus, wintergreen and mint. It also contains a very small amount indeed of carbolic acid, much less than that stated. We have been unable to identify certainly the presence of glycerin, and it is doubtful if it be present. From the result of the analysis we feel confident that the preparation is to all intents and purposes a mixture of boric acid and sulphate of zinc. The carbolic acid, thyme, eucalyptus, wintergreen, etc., if present, are present only in sufficient amount to give the compound a satisfactory odor. In view of the fact that J. S. Tyree has given wide publicity to a formula which the preceding report has shown to be a deliberate misrepresentation of fact, it is recommended that the article be refused recognition by the Council on Pharmacy and Chemistry, and that this report be published in the _Journal of the American Medical Association_. The recommendation of the subcommittee was adopted by the Council in accordance with which the report is published. W. A. PUCKNER, _Secretary_. In a letter to the editor of the _Journal of the American Medical Association_, Mr. Tyree admits changing the formula of the powder, and says that it had been his intention to state to the medical profession his reasons for making the change. In commenting on the letter it is noted that Mr. Tyree does not state whether the change was made one year ago or five years ago, but the sample for the first analysis was purchased last February, and the first chemist’s report was submitted to the Council March 5, 1906. On April 4th, Mr. Tyree was notified by the Council that the composition of “Tyree’s Antiseptic Powder” did not correspond with the formula published by him. Whether or not Mr. Tyree is justified in offering to physicians a preparation as composed chiefly of borax and alum, when in reality it is composed of boric acid and zinc sulphate, is left for physicians to judge.
