    Dr. Hartwich describes the following barks from the Museum of the Society. a. Sattion i '((ssi((.—This is the Annam cinnamon of Dr. Henry {Pharw. J()ii))t. [4], VI., p. -i7), and is official in the United States Pharmacoprcia, 1894, iinder the name of Saigon cinnamon. Dr. Hartwich considers it distinct from ('. ('a^sia for the following reasons:— 1. The secondary fibres are extremely few and small, their diameter being 21 to 25^^ to 2u'S^. the avei'age being 28-6^, as against those ot ('. ('assia, which are 24 to 40/^, according to Pfister, or 15-45;^, accoi'dingto Tschirch and Oesterle. 2. The raphides are always acicular and abundant, sometimes forming thick tufts, measuring in the parenchyma of the primary bark 8-6;u, and in that of the secondary bark 21-5^, and in the medullary rays 172^. In ( '. Cassia they are more slender, in the medullary rays the largest are 7*6^; they are not found in the primary bark. 3. The secretory cells of the secondary bark are abundantly present, but measure only 64-5 to 73-1^, or an average of 68-8^ at their largest diameter, those of ('. Cassia being 60 to 100/^ according to Pfister. 4. The mixed sclerotic ring in the primary bark presents no special features, the bundles of the primary fibres being almost wholly surrounded by the stone cells, so that the outer surface of the ring is limited by the parenchyma of the primary bark. Thick Chinese Cassia (four specimens). These were presented to the Museum by Messrs. A. S. Watsonand Co., of Hong Kong. The Chinese value them respectively at twenty-five and thirty times their weight of silver, and the fourth at 10 dollars (per catty?). A similar thick bark is mentioned m a Phariiiaroi/rajihid. sent by Dr. H. F. Hance, Vice-Consul in Whampoa, and valued at 18 dollars per catty (G5 francs for 484 grammes), p. 54. Dr. Hartwich considers all four to be derived from the sam ■ source, viz., <'. Cassia, or possibly forms of it. In this respect his ' opinion coincides with that of Dr. Pfister.
