" Royal," only, found free from lime, alum, and phosphatic acid, and absolutely pure. Under the direction of the New York State Board of Health, eighty-four different kinds of baking powders, embracing all the brands that could be fouad Lor sale in the State, were submitted to examination and analysis by Prof. C. F. Chandleu, a member of the State Board and President of the New York City Board of Health, assisted by Prof. Edward G. Love, the wellknown United States Government chemist. The official report shows that a large number of the powdera examined were found to contain alum or liiue ; many of them to such an extent as to render them seriously objectionuble fur use in the preparation of human food. Alum was found in twenty-nine samples. This drug is employed in baking powders to cheapen their cost. The presence of lime is attributed to the impure cream of tartar of commeree used in their manufacture. Such cream of tartar was also analyzed and found to contain lime and other impurities, in soine samples to the extent of 93 per cent of their entire weight. All the baking powders of the market, with the single exception of "Royal " (not including the alum and phosphate powdeis, which were long since discarded as unsafe or inefficiënt by prudent housekeepers), are made from the impure cream of tartar of commerce, and cousequently contain lime to a corresponding extent. The only baking powder yet found by chemical analysis to be entirely from lime and absolutely pure is the "Royal." This perfect purity results from the exclusive use of cream of tartar specially refined and prepared by patent processes, which totally remove the tartrate of linie and other impurities. The cost of this chemically pure cream of tartar is inuch greater than any other, and it is used in no baking powder but the " Royal." Prof. Love, who made the analyses of baking powdera for the New York State Board of Health, as well as Lor the Government, says of the purity and whulesonieness of " Royal" : "I have tested a package of 'Royal Baking Powder' which I purchased in the open market, and find it composed of pure and wholesome ingredieqts. It is a cream of tartar powder of & high degree of merit, and does not contain either alum or phosphates or any injurious substances. " E. G. LOVE, Pa.D."
