to neutraliEe the lima to some extent by tho aid of chemicals, and tiis method was resOrted to in order to procure cream of tartar in small quantities for pharmaceutical pur- poses, but t was open to serious objection in view of tho fact that tho chemicals employed for this purpose were not always washed out but re. raained in quantities that were unoer- tam and preudieial to is quality. The supposed impossihihty of re,noy- ing the lime has accordingly, caused cream of tartar to be chased and sold as pure when it did not eontatn more than five per cent of this ilnpnmty. The major part, however, of that used in commerce, or for culinary purposes, contains the tartrate of lime to an ex- tent much greater than five per cent, not infrequently being found, upon analysis debased to . dcgree equalling one-tourth or moro of its entire weight
 In report upon the subject of food adulteration made to the Now York State Board of Health by Professors Chandler and Love, it is stated that of P samples of cream of tartar bought from dealers as pure 16 were adulter- ated with various substances from 3 to 93 per cent, while of tho remainder all contained tartrate of lime, some as high as 1895 per cent.
 The serious character of this adul- teration is more readily appreciated when t is reeolIected how largely cream of tartar enters into the prepa- ration of the food of every family. In connection with soda in baking DOW. der it is the chief agent now employed for raising and making tight and di- gest,ble all our biscuit, cake aud other pastry, and is besides, in many com munities, approaching the old-fash, toned yeast for all leayeniug purposes, 50 that it is employed to some extent in almost every meal of which we eat. The amount of cream of tartar used in this country in a year in baking powder and otherwise in the prepara- ton of food, is estimated at ten mil, lion pounds, If tllis were % per cent pure-a high estimate We would con sume one million pounds or more oi lime annually as a substitute for bread. So large a deterioration be, comes appreeiable in the deprivation of our food of portion oft nutgitiye elements, not only, but fl, as is now supposed, this excess of hme taken in. to the system has a relation to the painful affections of the kidneys 80 prevalent in this country, it's bearing upon the health of the entire commu. nlty is too important to be overlooked
 The new process by which cream oi tartar is produced 100 per cent pure ..t.lhst,Is.-lgsG -lgsGish the lime totally elinlina. ted, by treating the crude material uader pressure instead of using any chemicals whatever for the purpose. was the discovery originally of a Ger man chemist, but has been developed and perfected by the Royal Baking Powder Company of this cig, through whose efforts a few years since in De- half of the high standard of purity in food, the pubic was rid of the. poison. ous alum baking powders at that time so prevalent
 The determination of this Company to place upon the market only abso. lutely pure goods, and tho impossibil. ity of doing this from tue cream ol tartar Of commerce, made it apparent that some new method must De sought by which cream of tartar could be procured in large quantities free from lime and chemically pure. The cream of tartar refners of this country and Europe when approached upon the subject, declared such result impos- sible, and declined 10 incur the expen. diture necessary to make the trial. The Royal Baking Powder Company, accordingly, resolved to solve tht problem for itself; and having secured the aid of the best chemists Of Europe and America, proceeded with it's in. yestigahons and discoveries until the result, after several years of labor and the expenditure of over half a million dollars in the purchase of patents, DOT. fecting ofprocesses end tho erection of buildings aud machinery, was reached in the complete attainment oi the end sought 1'he works (now owned by the New York Tartar Co.1 are located in Brooklyn, and exceed in size and capacity any other similar refinery in the world They produce . chemically pure cream of tartar, which $ now exclusively used for pharmaceutical preparations and in the manufacture Of the celebrated Royal Baking Powdor
