    478. Croton suberosum, continued. b. Bark in corky quills. (GorJcij Copalchi Bark, Chiquiqui Bark, Natri Bark, Qidna Blanca of Mexico.) Note.—This specimen has no history attached to it, hut isprohahly that described by Stark in the P. J. [1], vol. ix., p. 463, since the label ascribes it to the species to which he refers it, and gives the synonyms mentioned by him. It is identical in taste and appearance with specimen a, and not with the bark of Croton pseudo-China, Schlecht, to which Stark refers it. 479. Croton species. a. Bark. Note.—This specimen was presented by Mr. J. Collins. It was im- ported from San Juan in Mexico, and offered for sale in London in 1869. It is not bitter, and has a taste resembling that of Turkish oil of geranium (oil of ginger grass). Its botanical source is unknown. b. Bark said to contain quinine. Presented by Mr. J. E. Howard. 480. Croton Tiglium, L. a. Seed. See Bentley and Trimen, Med. Plants, tab. 239. b. Fixed oil, obtained from the seeds in England. {Croton Oil.) c. Ditto, imported. d. Croton cake, from which the oil has been expressed. e. Husks of the seed. Note.—The oil expressed in England is more esteemed than that im- ported from India. Pharmacographia, p. 509. The English oil is darker in colour than the Indian. Hypercatharsis produced by croton oil may be controlled by copious draughts of diluted lemon or lime juice or vinegar. Ind. Pharm., p. 201. East Indian oil forms a milky mixture with its own weight of alcohol (0-796), which ultimately separates ; but English oil dissolves, and forms a clear solution under the same circum- stances. Pereira suggests that the East Indian oil may be adulterated with jatropha oil, which is not soluble in twenty-four parts of alcohol. See Per. Mat. Med., vol. ii., pt. i., p. 411. 481. CuRCAS PURGANS, L. (English Physic Nuts.) a. Seeds. (Physic Nuts, Polga Nuts, Pinheiro de Purga, Pinhao Paraguay.) Presented by Mr. Morson. b. Oil expressed from the seeds. (Oil of Wild Castor Seeds, Jatropha Oil.) Note.—These seeds are in size and shape like those of the castor oil plant, but have a dull, black, cracked surface. Christison states that twelve to fifteen drops of the oil are equal to one ounce of castor oil, but the action of the drug is uncertain. The oil is only sparingly soluble in alcohol. See Ind. Pharm., p. 203. The leaves have been used as a cataplasm to producelactagogue effects. For fig. of seed see Hist, des Drog., vol.ii., p. 355. See also Per. Mat. Med., vol. ii., pt. i., p. 427; P. J. [1], vol. v., p. 25 ; vol. vii., p. 210 ; [2], vol. vii., p. 554.
