(11) CINCHONA MUTISII, Luml. 

 Var. a. MICROPHYLLA, Wedd. 



a. Long (jiiills, with periderm. 



Note, This specimen "contains quinidine." See P. J. [1], vol. xii., 

 p. 174, No. 13. The quills resemble those of 0. micrantha, but have 

 simply an astringent taste, and a smooth not a dusty coat, and " readily 

 split longitudinally." (J. E. H.) 



Far. 0. CEISPA, Wedd. 



a. Small quills. 



Note. Thia 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 Bark.) 

 Var. a. URITCSINOA, Pav. p. J. [2] , vol. viii., p. 15. 

 a. Slender quills. See P. J. [1], vol. xi., p. 494. 

 6. 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" quills, " 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 b " 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. 7, Bon- 

 plaudiana, 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. CONDAMINEA, How. ; var. /3. CHAHUARGUERA, E. et P. 

 (Huamalies Bark, Rusty Crown Bark.) . 



a. Slender quills. See P. J. [1], vol. xiv., p. 63, No. 10. 



b. 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 (crystallized as sulphate) ... 0-43 



Quinidine and uncrystallizable quinine ... 0-90 



1-33 



Specimen 6 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 



Cinchonine 0-68
