Mr. Tyree does not state when he changed the formula. We do not know whether it was a year ago, five years ago or ten years ago, but we do know that the package which was used in making the first analysis was purchased as early as last February, and the first chemist’s report was submitted to the Council March 5, 1906. On April 4 Mr. Tyree was notified by the Council that the composition of Tyree’s Antiseptic Powder did not correspond to the formula published by him. Whether or not Mr. Tyree is justified in offering our profession a preparation as composed chiefly of borax and alum when in reality it is chiefly composed of boric acid and zinc sulphate, we leave physicians to judge. Discrepancies Between Facts and Claims--Unfortunate Attempts of Mr. Tyree at Explanation A report from the Council on Pharmacy and Chemistry on Tyree’s Antiseptic Powder appeared in The Journal, Oct. 20, 1906. This showed that the preparation, advertised as a “scientific combination of borate of sodium, alumen, carbolic acid, glycerin and the crystallized principles of thyme, eucalyptus, gaultheria and mentha, in the form of a powder.” was essentially a mixture of boric acid and sulphate of zinc--approximately four-fifths of the former to one-fifth of the latter. “The carbolic acid, thyme, eucalyptus, wintergreen, etc., if present, are present only in sufficient amount to give the compound a satisfactory odor.” As will be remembered, in the correspondence published at that time, Mr. Tyree attempted to explain the discrepancies between his statements and the proved facts by intimating that he had recently changed the formula, and that it was his intention “on or about the first of February to state to the medical profession his reasons for changing the formula,” and that the change had been made “a short time ago, at the suggestion of several prominent gentlemen.” Since that time, through circulars and other advertisements, Mr. Tyree has attempted to explain the matter in various ways. In his latest circular letter he seems to make a deliberate attempt to mislead our profession and to misrepresent facts to a degree that makes it almost impossible to believe that the circular came from a man who claims to be honorable.
