liquor and exposed to the air, the wetted part assumes a red 
tint in about a minute or two; it then turns to violet, and, 
lastly, becomes blue. The same reaction takes place, but 
not in so short a time, if the starch-paper be allowed to re- 
main in the liquor. 
This effect, which is no doubt due to the decomposition 
of the bromide of iodine by the organic matter of the paper, 
and probably by the starch itself, affords the means of de- 
tecting the m'inutest quantities of iodine in the bromides of 
the alkalies.

ART. XXV.^-NOTES ON THE TALLICOONAH OR 
KUNDAH OIL. 
BY MR. ROBERT CLARKE. 
Senior Assistant Surgeon to the Colony of Sierra Ltfone. 
The tree which furnishes the nuts from which Talli 
coonah or Kundah oil is procured, is found growing abun- 
dantly in the Timneh country and over the colony. At the 
village of Kent, near Cape Schilling, the oil is manufactured 
as follows: — The nuts are dried in the sun, then hung up in 
wicker racks or hurdles, and exposed to the smoke of the 
huts; when exposed for a sufficient time, the nuts are 
roasted and subjected to trituration in large wooden mortars 
until reduced to a pulp. The mass is then boiled, when 
the supernatant oil is removed by skimming. The natives 
principally manufacture the oil to afford light; the leaves 
are used by the Kroomen as a thatch.
