In further justification of the Council’s protest against the provisions of our present law, or the methods of its enforcement, which permit the granting of patents without thorough and scientific investigation of the claims advanced in such letters patent, the Council calls attention to the report, appearing above, of an investigation made by A. J. Carlson, A. E. Kanter and I. Tumpowski, “The Question of the Stability of Secretin,” which relates to U. S. Patent No. 1,181,424, issued to James Wallace Beveridge.

Whereas the regulations governing the issuance of patents demand that the processes shall be described in such detail that one versed in the sciences can confirm the claims made by the patentee, no pretense whatever of fulfilling this requirement is made in the patent specifications of this patent. The substance of the first three paragraphs of this patent has long been general knowledge. Nearly every sophomore medical student has himself performed, or seen performed such “experiments” as are therein described. The claims of novelty evidently are confined to the assertion that the preparation is able to “resist oxidation or deterioration”; that it is free from “poisonous and irritable chemical substances”; that it “may be administered orally to produce the desired physiological action.” etc., etc. Not the slightest hint is given as to how any person can substantiate these claims. As a matter of fact, the investigation of Professor Carlson and his co-workers has shown that a preparation having the properties claimed cannot be made by the process described in this patent. Any one familiar with the subject could have demonstrated readily that the applicant was withholding information concerning essential features of his process, assuming that he had any information on the subject (which he probably did not have) and would have advised against the issuance of the Beveridge patent.—(From The Journal A.

SURGODINE

Report of the Council on Pharmacy and Chemistry

The following report submitted by a referee was adopted by the Council and authorized for publication.

W. A. Puckner, Secretary.

Surgodine (Sharp and Dohme, Baltimore, Md.), according to an advertising pamphlet, is a solution of 214 per cent. of iodin in alcohol, containing no alkaline iodid, but miscible with water in all proportions. The A. M. A. Chemical Laboratory reports that Surgodine is an alcoholic liquid (containing 91.8 per cent. alcohol by volume) containing free iodin, combined iodin and free acid, probably hydrogen iodid (hydriodic acid). Quantitative estimations gave 2.51 gm. free iodin per 100 c.c. and 1.78 gm. combined iodin (the greater part apparently was present as hydrogen iodid).

It is therefore similar to several other iodin preparations already considered by the Council. Like these, it is essentially similar to the official tincture of iodin, except that it is considerably weaker, and instead of potassium iodid it presumably contains hydrogen iodid and probably ethyl iodid to render the iodin water-soluble. Its composition, however, is secret.

There would be no objection to the use of ethyl iodid or hydrogen iodid, except perhaps the acidity of the latter, as a solvent agent rather than of potassium iodid. But neither is there any important advantage, and these preparations would have to be considered as unessential modifications of official preparations, and therefore ineligible for New and Non­official Remedies.
