Camphor.

Syn. Camphre (F.), Der Karapfer (G-), Canfora (7.), Alcanfor (S.)» Cafoor(Arab), Carpoorum (Tarn), Carphura (San.).

That the Camphor brought to Europe, from the islands ofSumatra and Borneo, is not the product of the Laurus Cam-phora, was remarked by Kcempfer '; but no accurate descrip-tion has yet been given of the tree which yields it. Mr. H. T.Colebroke has, however, lately been enabled to determine thegenus to which it belongs, and to which we have referred it,from the examination of some seeds in a very perfect state,sent from Tapanooly to Calcutta.

The Dryobalanops Camphora is a native of forests on thenorth-western coast of Sumatra, and especially in the vicinityof Tapanooly. It is stated by Mr. Prince to be found inabundance from the back of Ayer Bongey, as far north asBacougan, a distance of 250 miles. It grows to a great height,and the trunk, which is arboreous and covered with a brownishbark, often measures six or seven feet in diameter. The leavesare opposite below and alternate above, elliptical, obtuselyacuminate, or rather beaked, parallel veined, entire, smooth;3.7 inches long, 1.2 broad, and supported on short petioles iwith subulate, caducous stipules in pairs. The perianth is aone-leafed, five-parted, persistent capsule, which is superior,ovate, woody, fibrous, longitudinally furrowed, embraced atthe base by the calycine hemispherical cup, and surroundedby its enlarged leaflets, which are converted into remote, fo-liaceous, spatulate, rigid, reflex wings : one-celled and three-valved. The seed is solitary, conforming to the cavity of thecapsule; and has a strong terebinthinate fragrance.

The camphor forms in the heart of the tree, occupying por-tions of a foot and a foot and a half long, at certain distances:
