"In another column we publish a letter from Dr. W. Oliver Moore, calling attention to an injustice that certain competing pharmacists have practiced toward Messrs. Mariani & Co., in 'pirating' published records of the successful use of the Mariani preparations of Coca, and at the same time craftily making these records appear to apply to their own preparations. It is very much to be regretted that a house that has been so punctilious in avoiding even the semblance of any offense against the courtesy of trade should have been treated in this shabby way by some rival manufacturers." 31 Rue Guénégaud, Paris, Dec. 8, 1887. _To the Editor of the New York Medical Journal_: SIR—Will you kindly have it announced in your journal, in justice to myself before the medical profession, that the various notices appearing in journals and circulars quoting my name in connection with Coca are entirely false and in every respect a prevarication? The only preparation of Coca employed by me with undoubted and uniform success has been the so well-known _Vin Mariani_, which, since 1865, I have had occasion to prescribe daily in my _clinique_, as well as in private practice. My opinion of this valuable medicament has, during many years, been frequently made known for the benefit of the profession in various writings, and it is but just to this worthy preparation that it receive all the honor due it. I thank you for compliance with my request. CH. FAUVEL, M.D. Continued compliment is paid M. Mariani for the maintained high standard and excellence of his preparations, by the numerous honorable mentions and indorsements by the members of the medical profession and those who have occasion to use his Coca preparations; latterly through the following awards: Gold Medal and Silver Medal from the Académie Nationale de France; Gold Medal and a Grand Diploma of Honor from the Wine Exhibit of Bordeaux, France; Gold Medal and a Diploma of Honor at the Hygienic Exhibit at Amsterdam, Holland, and a Gold Medal and Diploma at Leamington, England, the jury surnaming his _Vin Mariani_, "Wine for Athletes." N. B.—Professional bicyclists and athletes, after careful trials of ours and preparations of others, among which the Cafeine. Theobromine, Kola, pseudo-Cafeine or Kolamine (Knebel), Maté, etc., invariably give the preference to our Coca preparation. Messrs. Dubois, Lucas, Vigneaux, Echalié, André Henry, Imans, Buffel, and many others have attested to the vast superiority of Coca Mariani over all other tonics (dynamogéniques). We request those physicians, who kindly place confidence in our preparations, to prescribe them under the name of _Mariani_, and to insist that their prescriptions be scrupulously executed.
