    98. (11) Cinchona Mutisii, Lamh. Var. a. MiCKOPHTLLA, Wedd. a. Long quills, with periderm. j^ote.—This specimen contains quinidine. See P. J. [1], vol. xii., p. 174, No. 13. The quills resemble those of C. micrantha, but have simply an astringent taste, and a smooth not a dusty coat, and readily spht longitudinally. (J. B.H.) Var. p. CRISPA, Wedd. a. Small qnills. Note.—This specimen contains quinine. See P. J. [1], vol. xii., p. 174, No. 9. The bark of C. Mutisii is rarely met with in English com- merce. According to Weddell it contains only aricine, 0-23 per cent. See Trans. Wedd. Notes, p. 33. (12) Cinchona officinalis, L. (Pale Baric.) Var. a. Uritusinga, Fav. p. J. [2], vol. viii., p. 15. a. Slender quills. See P. J. [1], vol. xi., p. 494. h. Larger quills. See P. J. [1], vol. xiii., p. 671, No. 3. c. Crown bark from Java, 1871. d. East Indian bark, 1872. Note.—Specimen a consists of fine old Loxa qmlls, found in the London Docks in 1850, and supposed to have remained there for 25-30 years previously, and therefore possibly some of the original Crown bark. It is tied up with bast, as it was then the custom to do with select specimens of bark. Specimen h seems to be the Colorado de Loxa of Pavon. It is remarkable for its rough surface and the quantity of red colouring matter it contains. It differs from the bark of var. y, Bon- plandiana, in being of a dark grey colour, and in not being warty, although marked with innumerable fissures. The East Indian and Java barks may be recognised by their dark grey colour and branching cracks with thick edges. For. fig. of plant, see Bentley and Trimen, Med?Plants, tab. 143. Var. /3. CoNDAMiNBA, Bow.; var. /3. Chahuargheea, E. et P. (Muamalies Bark, Rusty Crown Barh.) a. Slender quills. See P. J. [1], vol. xiv., p. 63, No. 10. h. Larger quills. See P. J. [1], vol. xiii., p. 671, No. 4. Note.—Specimen a is the rusty Crown bark, or Huamalies bark, of Pereira. Vol. ii., pt. ii., p. 100. (The Huamalies barks of Guibourt and Bergen are not identical with that of Pereira. See P. J. [1], vol. xiv., p. 63.) Analysed by Howard, this specimen yielded— Quinine (crystalUzed as suliDhate) ... 0*43 Quinidine and uncrystallizable quinine ... 0-90 1-33 Specimen b is the knotty sort of Jussieu. The small brown dots visible in the younger quills have in this variety developed into large warts. Analysed by Howard, this specimen yielded— Quinidine 1«67 Uncrystallized quinine 0-63 Ciuchonine 0-68 2-98
