    Knowing, however, the view which is often held on the subject of standards for manufactured I felt I could only describe these samples as of doubttul purity. The natural corollary is that an authoritative definition of chocolate is required. GROUND CINNAMON. The results of analysis of seven samples were far from satisfactory, three of the samples containing proportions of sand, as indicated by the high “ msolub e ash.” Genuine cinnamon of good quality yields con- siderablv under i per cent., whereas these samples vielded 2*68, 2-95, and 4.1 per cent.respectively; the last of these was returned as adulterated. A fourth sample contained about 5 per cent, of arrowroot. CREAM OF TARTAR. The 11 samples all contained a satisfactory propor- tion of real Bitartrate of Potassium, but several samples contained excessive amounts of lead or copper. In a report issued by the Local Government Board m i 907 Dr A W. MacFadden approves the “ Cream of laitar standard ” already adopted by traders and analysts, m which the limit of impurity is fixed at an amount not exceeding *002 per cent, (approximately ] gram per lb.) of lead. A similar amount has also been proposed as the limit for contamination with copper. Judged by these standards three of the samples examined must be considered as adulterated, and two as of very poor or doubtful quality ; the actual results obtained were No. 192 Lead -0033 per cent.
