Vincent, Esq., Deputy Minister of Inland Revenue. Sir : — I beg to hand you a report upon 65 Tablets containing Aspirin analyzed in these laboratories. ' > * Inspection of this article was made on account of complaints origrinating in Chicago, where Canadian made tablets were suspected to be spurious and fraudulent. So far as the work ."Htorded goes, it shows the Canadian made article to be of very sood quality. The tablets nominally contain 6 grains of aq>irin, and the variations found are not in excess, for the most part, of normal variation for machine made tablets. I beg to recommend publication of this report as Bulletin No. 856. I have the honour to be, Sir, Your obedient servant, A. Moonx. Chief AtMlytt.
