298. (12) CINCHONA OFFICINALIS, continued. 



This variety (Chahuarguera, Par.) is that which had the reputation of 

 curing the Countess of Chinchon. It may be distinguished from other 

 pale barks by its rusty brown aspect and minute brown dots or warts, 

 which latter are often in the larger quills split like a coffee berry.

This variety of East Indian bark is easily recognised by its broad bright 

 brown stripes, on a dark ground, caused by longitudinal cracks with 

 thick edges, exposing the interior. It is of excellent quality, yielding 

 7-8 per cent, of alkaloids. See P. <7. [2] , vol. viii., p. 593, No. 4, 5.

Note. This " appears to be the same as the amarilla del Eey of E. et 

 P. in the British Museum." " It is the bark described under the heading 

 of a in Per. Mat. Med., 3rd ed., vol. ii., pt. ii., p. 1639 ; and the C. lutea 

 and amarilla del Eey of Pavon." This bark is of a dark grey colour, with 

 very numerous transverse cracks, interspersed among which are numer- 

 ous small raised warts of the same colour as the bark. The Crown 

 bark from Java somewhat resembles this bark in appearance.

a. Slender quills. P. J. [1] , vol. xiv., p. 61, No. 9. 

 Note. This specimen is the " silvery Crown bark " of Pereira, and has 

 been clearly identified with specimens taken by Seemann from C. offi- 

 cinalis, a. Vera, Wedd. See Per. Mat. Med., vol. ii., pt. ii., p. 1609, note 3. 

 It is the true Loxa bark of Humboldt, and the cascarilla fina de Loxa of 

 Euiz and Pavon. It is also the quina, or crespilla carrasquena of old 

 authors, and the quina fina de Loja of modern trade. P. J. [2] , vol. 

 viii., p. 16. Analysed by Howard, it yielded 



Quinidine and uncrystallizable quinine ... 0-40 

 Cinchonine ... ... ... ... ... 0-03

East Indian bark obtained from this species yielded only 0-629 per cent, 

 of alkaloids. See P. J. [2] , vol. viii., p. 593. The specimen in this 

 collection is remarkable for the thick edges of the numerous ramifying 

 fissures, which form a sort of raised network on the bark. , It closely 

 resembles in size and colour the East Indian Uritusinga bark.

a. Flat pieces. 



Note. This specimen much jesembles Calisaya in appearance, but is 

 not so bitter, and has the remains of a silvery periderm.
