In eight samples the percentage of all three constituents was beyond the standard limits. The same was true in 14 cases of two constituents and in five cases of one constituent. Only one sample, No. 5487, was not condemned by any of these three determinations, but the ether extract from this showed no crystals of piperine and contained but 1.88% of nitrogen. Two samples of buckwheat middlings analyzed at this Station (see Report for 1886, p. 111 and for 1888, p. 152) contained 7.55% and 8.06% respectively, of ether extract. A pepper may have the normal percentage of extract and yet be grossly adulterated with this product. Fortunately we have other means for detecting the admixture with certainty. Black Pepper Suspected of Adulteration.-In Table XIII are included four samples of this class from packages bearing the name of the manufacturer or dealer, and eight sold in bulk. No foreign matters were detected in these samples by the microscope, but chemical analysis indicates either the addition of pepper shells, or that the samples were ground from uncleaned peppercorns. An analysis of a sample of "pepper shells" offered to the "trade" at one and three-quarter cents per pound in 25 ton lots, is given below, together with an analysis of long pepper. TABLE XIII.-BLACK PEPPER SUSPECTED OF ADULTERATION. White Pepper, Pure and Adulterated.—In Table XIV are given analyses of seven samples of white pepper, two of which are adulterated. To recapitulate: 102 samples of pepper have been examined. About 66 per cent. of the samples in packages were pure, about 52 per cent. of samples sold in bulk were pure. Station No. Brand.
