of the twigs acts as a vermifuge ; the oil of the berries, wliich are aromatic, is 

 stimulant. These berries are said to have been used in the United States during the 

 American war as a substitute for Allspice. Laurus nobilis has also aromatic leaves, but 

 they are chiefly used by confectioners. Among fatty matters may be mentioned that of 

 Tetranthera Roxburghii, whose fruit yields a greasy exudation. It is a fixed oil which 

 is supposed to constitute the principal part of the fi-uit of Persea gratissima, so much 

 esteemed in the West Indies under the name of the Avocado Pear. Camphor is by no 

 means an uncommon secretion of these plants. It occm's abundantly in some species 

 of Cumamomum, especially in their roots, which are so much contaminated by it 

 as to be unfit for use as a spice. The Camphor of commerce, however, or Chinese 

 Camphor, is obtained in Camphora officinannn from the wood, branches and leaves, by 

 means of dry distillation. It is a kind of Stearoptine remaining after the Elceoptine or 

 ethereal oil of the five tree is evaporated. — Nees. It is chiefly produced in the island 

 of Formosa, and brought by the Chmchew junks in very large quantities to Canton, 

 whence foreign markets are supplied. In some cases a volatile oil is obtained fi'om the 

 Laurels in large quantities ; that of Oreodaphne opifera, a tree found in vast forests 

 between the Oronoko and the Parime, is produced in great abundance by merely 

 making an incision into the bark with an axe, as deep as the fiber. It gushes out in 

 such quantity, that several quarts may be obtained by a smgle incision. It has the 

 reputation of being a powerful discutient. The fruit of this tree yields upon distillation 

 a limpid volatile oil of a yellow wine -colour, an aromatic acrid taste, and smell as if old 

 oil of Orange-peel had been mixed with oil of Rosemary. It is used in Brazil in contrac- 

 tions of the joints, pains in the limbs, and similar cases, under the name of Canella de 

 Cheu'o. — Martius.
