BOTANICAL INFORMATION. 157 
of the “Doon” (Doona Zeylanica, Thw.), and ** Wenewell " (Pereiria 
fenestrata, Lindley): the first likely to become of economie value, as 
yielding an excellent Gum-resin; and the latter of medicinal impor- 
tance, as a substitute for Calumba-root. ; 
Having already, in a communication to Government, drawn the atten- 
tion of the Chamber of Commerce to the Doon-tree just referred to, as 
well as to the ** Gokatoo,” or true Gamboge of commerce, it is unneces- 
sary for me to repeat here what I then said; but I would observe that 
Ilose no opportunity of making inquiries respecting the productions 
of this country; and during my excursions into the jungle the chief 
objects of my search are such plants as are likely to prove of direct value. 
. I have collected several species very closely allied to the Gutta Percha 
tree, but have not yet found the true one, though it is far from impro- 
bable that it may occur here, or some allied species possessing the same 
properties. ; 
In concluding this Report, I would take the liberty of suggesting 
how important might be the result -of the encouragement by Govern- 
ment, in different parts of the island, of such experimental gardens as 
the one contemplated at Kurnegalle. These gardens might be supplied 
with plants and seeds from this establishment: and I should consider it 
my duty, and it would be a very gratifying one, to render all the as- 
sistance in my power to such undertakings. This would seem to be 
the best, if not the only plan, of introducing to any extent amongst the 
native population, improved varieties of plants and better modes for 
their cultivation.

(From the ‘ Singapore Local Reporter, August 7.) 
A produce of Borneo, which we think could be obtained in our 
island, and from the neighbouring state of Johore, has been brought to 
market here within the last few months; and although the quantity 
imported was trifling, from all the information we have collected and 
from our own personal observation, we are led to believe that in a short 
time this article will constitute an important part of our local trade; for - 
according to letters in our possession, received from persons well ac- 
quainted with the matter, it has been ascertained that Messrs. M‘Intosh
