mountains of Uritusinga, near Loja. This is the Czuchona 
Uritusinga of Pavon, also the Quina-quina described by 
M. La Condamine, in 1738, and consequently the C. acade- 
mica of Guibourt’s “ Hist. des Drogues,’ and the C. officz- 
nalis of Woodville’s “ Botany,” vol. iii. p. 546. The plant 
flowered in the writer’s possession in 1862, and a charac- 
teristic drawing, by Fitch, of the flowering branch, may be 
found in tab. 5,364 of Curtis’s “Bot. Mag.,” which may 
be compared with that of the same species in the “ Neuva 
Quinologia.” 
A plant of the above, about six feet in height, was 
presented by Mr. Howard to the Indian Government, and 
although it suffered from a sunstroke in the transit from 
Madras to Ootacamund, and lost all its leaves, it was 
restored, and, by the skill of Mr. M‘Ivor, increased by 
cuttings to the extent of now between 6,000 and 7,000 
plants. It has since flowered, and a characteristic specimen 
has been brought home by Mr. Markham, together with a 
portion of the bark. 
A sister plant of the above, together with another, its 
direct descendant, suffered from an irruption of smoke into 
the stoves in the past winter, and Mr. Howard was com- 
pelled to cut them down. This gave the opportunity for 
examining the bark, which yielded on percentage of the 
dried bark :—

A produce very much the same that bark of the same kind 
and age might have yielded in its native climate, and pro- 
bably the first extracted from bark grown in Europe. 
Although this kind has nearly become extinct in its 
native region, it may regain its place in pharmacy, as it 
seems well adapted to India, and flourishes on the 
Neilgherries at an elevation of about 6,000 feet. 
Several other forms range themselves around this which 
we now constitute the central plant of the group, by 
restoring its original name. Mr. Howard ventures to pro- 
pose the following arrangement of these, as one rendered 
necessary for the distinction of the barks in commerce, as 
these will soon come from India, and as the only way that 
he ‘can see to extricate the subject from the confusion
