Anadol was analyzed at the Bureau of Chemistry and the chemists reported that it contained over 82 per cent. of Acetanilid. As the labels did not bear any statement as to the quantity of acetanilid contained in the nostrum, the stuff was declared misbranded and the defendant, on pleading guilty, was fined.--[_Notice of Judgment No. 795._] PIX CRESOL W. A. Puckner and W. S. Hilpert In a paper on “The Abuse of Chemical Formulas”[100] several examples were given of the various methods employed by “patent-medicine” concerns to give standing to their products by assigning to them a chemical formula. In some cases the formulas given are impossible, in other cases they may represent the chemical composition of only one constituent or it may be an attempt at both. To a chemist such formulas are absurd and on seeing a formula which he knows to be wrong he naturally thinks “Fake,” “Ignorance,” or both. Just such a formula (C_{5}H_{6}N.SO) applied to a product called Pix Cresol, manufactured by the Pix Cresol Chemical Co., Kansas City, Mo., attracted our attention. No mention of such a formula can be found in such works as Richter’s most complete Index of Carbon Compounds, nor the three supplemental volumes published, 1901-1905, by the German Chemical Society and Beilstein’s Organic Chemistry (3d Ed.). This fact, supplemented by inquiries from correspondents as to the composition of the substance made it seem worth while to make a chemical examination of it. [100] Puckner, W. A.: Report of the Chemical Laboratory of the American Medical Association, iii, 7. The examination was made and showed that the essential constituent was oxyquinolin sulphate. As potassium sulphate was also found it was concluded that Pix Cresol was a preparation containing a mixture of oxyquinolin sulphate and potassium sulphate, which has also been known in the past under the proprietary name, “Chinosol.” At this time a letter was referred to the laboratory containing the report of an analysis of Pix Cresol, which showed the presence of oxyquinolin sulphate but no potassium sulphate. As this indicated that Pix Cresol contained as its essential constituent the substance now sold as Chinosol, the laboratory purchased a new specimen of Pix Cresol from the Chicago representative of the Pix Cresol Co. The examination[101] of this specimen showed that it consisted of approximately 21 per cent. oxyquinolin sulphate, about 8.3 per cent. potassium sulphate and the remainder almost entirely milk sugar. [101] The analytical details will be published in the annual report of the laboratory.
