BRU—BRU a ie 
The ferruginous rust which covers this bark, and which 
resembles the het of iron, possesses fo 2 wise 
perties of that metal ; for if water, acidulated with mur 
tic acid, be agitated in contact with it, it assumes a beau- 
tiful green colour, and affords, with an alkaline prussiate, 
(bydrocyanate of potass,) a prussian blue precipitate. 
Late experiments have proved the existence in this bark 
of an alkaline proximate element, which has been called 
Brucia. According to the analysis of Pelletier and Ca- 
ventou, the bark contains—1, a fatty substance ; 2, yellow 
colouring matter; 3, gallate of Brucine; 4, traces of sugar; 
5, gum; 6, woody fibre. 
Has not been used in medicine—is a good subject for 
an inaugural thesis. cas 
Brucea Antidysenterica, of Bruce’s Travels into Abyssinia, 
vol. v. p. 69.) is described by L’Heretier, under the name 
erruginea. It is called Wooginos, and is sup’ 
by some to be the Angustura bark, No. 116, which it is 
“not—and a more serious mistake could not be. Dr. Rox- 
burg observes, that another species, the Brucea Sumatra- 
na, is fetid, and simply but intensely bitter, and promises 
to be as good an antidysenteric medicine as the preceding. 
It is called, in India, Amypadoo. 
A third species of Brucea was discovered by Dr. Horse- _ 
field, in Java, called Fraunalot by the Javanese: he says, 
it is of a bitter nature, and possesses properties somewhat 
similar to those of the Quassia simarouba. Another spe- 
cies is spoken of by the same author, under the Javanese 
name Patti-Lallar—native of Java—possessing the same 
_ qualities as the other species. ae 
No. 119.—Brumapunpoo. See No. 78. 
No. 120.—Brucra. (Brucine.) eS 
In 1819, Pelletier discovered, in the bark of Brucea antidy. 
senterica, an organic, salifiable base, which is intensely _ 
bitter, and slightly soluble in water; it unites with acids, _ 
forming neutral salts. Its action on the animal system is 
similar to Sirychnine, but weaker; is a narcotic. | 
Dose, from 1 to 3 grains—given in pills, tincture, and 
mixture. 
Nux vomica also contains Brucine ; but for medical purposes, 
that obtained from No. 118 should be used, because that 
_- from the vomic nut is apt to remain mixed with some 
__ strychnine, which increases its activity, and prevents cal- 
lation on its effects. 
The medical propertiag and uses of Brucine would form a 
good subject for an inaugural dissertation: much credit 
would be derived from a good experimental dissertation 
on this subject. = ae
