Herman's), fuses at from 65° to 62°, and affords from 7-3 to 6-4 per cent, of stearoptene.^ Sample No. 11 may be regarded with some suspicion from its resemblance to No. 12—the latter being acknowledged of inferior quality. Whether the differences that exist in the characters of the various kinds of Otto are the result of climate or of the method of manufacture, or whether (especially in the case of the Turkish Otto) they are to be traced to a difference in the species of rose are questions for determining which I have at present no sufficient data.

Africa—West Coast, also East Coast, including the Red Sea and Arabia. Copal.—Information is much desired respecting the varieties i859. of this substance which are found in commerce, and which are ex- ported from the West Coast of Afria. Some copal is believed to be dug from the ground, but one variety at least is collected from the tree. This is the Sierra Leone copal, and is produced by Guihourtia copallifera, Bennett—Koho of the natives : specimens of this tree, including the ripe pods, are requested : it grows at Goderich and in other localities near Sierra Leone. Grains of Paradise.—Although Amomum Melegueta, Roscoe, the plant which yields this drug, is now well known, there are some other interesting species nearly allied, with which botanists ^ The test used in Turkey by the persons who purchase Otto from the pro- ducers, is to plunge a small vial of it into water at 10° Reaumur (= 55° F.). If, in the space of five minutes the Otto congeals, it is regarded as genuine. ^ Extracted from the Admiralty Manual of Scient^c Inquiry. Third edition, 1859.$
