    202. Acacia Vekek, continued. g. Senegal gum. {Gomme Kuteera.) Note.—The variety du bas dufleuve is the most esteemed in French com- merce. Specimens d to g are gums which are found mixed with Senegal gum. Gomme vermiculee is white, transparent internally, and occurs in cylindri- cal curved pieces. Gomme pelliculee is of a reddish yellow tint, and has a sort of vegetable epidermis on various parts of its surface. It is not entirely soluble. Gomme Ugnirode is a very distinct gum, in large quite opaque pieces of a dull yellowish brown colour. It dissolves in water, leaving a residue of gnawed wood. It is known in French commerce as marrons. According to Guibourt, some other gums, viz., gum Kuteera (see Sterculia tragacantha), gomme verte, which is greenish at first but becomes yellowish white on exposure, and is difficultly soluble, bdellium and gomme Gonake from Acacia Adansonii (A. vera, Willd.?), distinguished by its bitterness and dark colour, are also found in gum Senegal. Senegal gum is known from gum arabic by its clear interior, fewer cracks, and toughness. See Hist, des Drog., hi., p. 440. h. Sennaar gum. (Sennari Gum.) Note.—This specimen is white, and looks like the best Turkey gum ; but among it may be seen pieces with a greenish tint. It yields a very glairy mucilage. It is the kind referred to by Hanbury in Pharmaco- graphia, p. 210, note 3. It probably is identical also with the gomme verte of Guibourt. In English commerce it is known as Sennari gum. 203. Acacia species. a. Maculla best gum arabic. So called, by a native doctor at Bombay. (P. 145.) Note.—This is the specimen alluded to in Per. Mat. Med., vol. ii., pt. ii., p. 335 (P. 145). It is probably of African origin ; for, according to Dr. Vaughan, African gum finds it way to Maculla. P. J. [1], vol. xii., p. 226. The specimen was presented to Dr. Pereira by Mr. Lawrence, Jan., 1834. h. East Indian gum. (P. 146.) Note.—This is called in India, Mocha and Barbary gum. c. Surat inferior gum arabic. (P. 147.) Note.—Specimens b and c are those alluded to in Per. Mat. Bled., vol. ii., pt. ii., p. 335. d. Calcutta gum arabic. e. East Indian gum arabic. /. Bengal gum arabic. Note.—The first three specimens came from Bombay. Specimen e seems identical with the gomme Ugnirode of Guibourt. See gum Senegal and Feronia elephantum. g. Unnamed specimen, resembling East Indian gum. h. Ditto, resembling Cape gum. i. Purified gum. Presented by Mr. H. Picciotto. P. J. [1], vol. ix., p. 1G. j. Insoluble gum. Note.—For adulteration of gum arabic, see P. J. [2], vol. v., p. 233.
