with small slender points on the interior; the odour of Quin- 
quina extremely faint ; flavour slightly bitter, and styptie with- 
out being nauseous. It is very little rolled. 7 
V. Cascarilla del Rey (Royal Cascarilla). 
The species to which this bark belongs, which is sold also 
under the name of red Quinquina, is still unknown. We shall 
give a description of it according to the specimens of M. Ruiz; 
he does not speak of it in his Quinologia. This bark, like the 
preceding ones, occurs in large and small pieces, the latter well 
rolled, the others only half, both pretty fine ; none are found ex- 
_ ceeding a line in thickness. Its epidermis is 
greyish and smooth ; internal surface ochrey inc 
fracture clear, with a few fibres towards the interior wiry ; its 
flavour styptic, and more disagreeable t nan bitter, with little or 
none of the aromatic odour peculiar to good Quinquinas. This 
bark presents on the ‘internal: surface almost the appearance of 
genuine red Quinquina ; but externally it resembles the bark of 
the eherry-tree. 
The genuine red Quinquina is readily distinguished from the 
other false or real Quinquinas that are sold under the same 
name. The second, third, and fifth, have an extremely smooth 
surface ; the epidermis greyish ; and there is not that uniformity 
. of colour i ‘in the internal parts which is observed i in the red Quin- 
- quina, which scarcely, even in the thick barks, presents a 
greyish shade. ~ All these Quinquinas, moreover, either have | 
the taste and smell of the first in a faint degree, or have a nau- 
‘seous flavour. As to the bark of the C. laceifera, it is so thick,
