same place. It is known by its yellowish colour, and especially 
by the facility with which it is bruised, or, as we may say, pul- 
verized, between the fingers. Its fracture is quite ligneous, 
and discloses in the interior a whitish fibre, whilst in good Cali- 
saya this circumstance is scarcely perceptible. _ 
The bitterness of the Calisaya is developed almost instanta- 
neously and in all its intensity, whilst in the Quinquinas of 
Loxa the bark requires to be chewed and macerated in the mouth, 
This bitterness continues long affer mastication, and is accom- 
panied with a certain disagreeable taste which excites nausea. 
The rolled Calisaya is less disagreeable, though not less bitter, 
and appears to us to have ry little apell. | 
IV. Quinquina eiiiilies the Calisaye 
M. Tafalla has sent from Peru some specimer 
quina. Under this denomination, and under that of Cascarilla 
provinciana, he collected this bark m the woods of Chicoplaya. 
The same species also occurs in the mountains of Monzon, which 
belong to the province of. the Hu: amal , and the discovery of 
itis to be ascribed to M. Bezares.* This bark has a perfect 
resemblance to the orange-coloured Quinguina of Mutis, and 
Messrs. Zea and Ruiz are rather inclined to believe that they 
may belong to the same species. 
* It is said thaf M. Bezares - diséévered- ‘at Monzon this species of Calisaya; it is also said, 
‘that he discovered at Monzon a Quinquina similar to the Calisaya, and which is thought to 
be of the same species with the Red Quinguina of Mutis.. It is s possible that in the discovery 
vof the ‘Calisaya, which is ascribed to Bezares, the question may be only on the discovery of 
this new Quinquina resembling the Calisaya, which, according to M. Ruiz, is very different from 
the Calisaya, as well as the orange-coloured Quinquina of Mutis, This doubt can be cleared 
up, only by the arrival of the specimens which M. Tafalla is to onset
