344 BOTANICAL INFORMATION. 
The same drug is contained in the Canara and Travancore collections ; 
the plant yielding these roots is unknown. 
8. Senna. A fine specimen of Tinnevelly Senna, cultivated near Cape 
Comorin, may be noticed as of a superior quality. It is satisfactory as 
. notice that Senna grown in the Southern provinces of the Presidency is 
highly esteemed in Britain, and preferred by many to all other sorts, as 
being both cheaper and purer. 
9. Catechu (Kuth, or Terra Japonica). Of this astringent there are 
many samples, which may be reduced to three varieties; these are as 
follows :—1. Circular flat cakes, from Travancore, covered on both 
sides with paddy-husks. 2. Large flat cakes, from the Northern Di- 
vision, varying in colour from brick-dust to dull yellow. 3. Round 
balls of a dark brown colour, the size of a small orange, from Manga- 
lore, where a large manufacture takes place. These two sorts appear 
identical, or nearly so, varying only in shape. There is likewise a piece 
of the wood of Acacia Catechu. 
10. Gambir, from Rangoon, in cubical cakes, covered with a Malva- 
ceous leaf. 
ll. Kino, the natural exudation of Pterocarpus Marsupium, is an 
article of export from the Malabar coast. Several specimens exhibited 
are quite identical with the Kino of commerce. 
12. Extract of Hyoscyamus. A large fresh specimen has been for- 
warded from Hoonsoor, prepared by Assistant-Surgeon Hilberse ; this 
quality of the extract has been thoroughly tested in the different civil 
dispensaries, and it has been pronounced equally useful with the Euro- 
pean article. Considering that this valuable medicine has been pre- 
pared for the first time in the Presidency, the Jury award a Second- 
elass Medal. 
—... 34. Gamboge has been forwarded from Goa, Mysore, Canara, Malacca, 
and Labuan. The specimen from Malacca, exhibited by Lieutenant 
. Evans, 51st N. L, is the finest pipe variety; all the others are in the 
form of lumps or tears. The series is very instructive, showing how 
much the commercial character of this product may be altered by trivial 
circumstances, the exudation being yellow, reddish, or brown, and of 
different degrees of solidity, according to the season of the year, and 
the method of manipulation. It has been shown that the peninsular 
Gamboge is a useful pigment, and an effective purgative. It has been 
tely added to the list of country medicines; and it appears that the
