Jesuits towards the latter part of the 18th century. Kemp 
made an examination of it, and came to the conclusion that it 
contained principles similar to those described by Pelouze and 
Fremy as existing in Orchella weed. Attfield in 1875 (Pharm. 
Journ. (3), V.5 721,) made a more complete examination, and — 
obtained a substance (chrysarobin), which he supposed to 
be chiefly chrysophanic acid. In the same year Dr. J. F. 
Da Silva Lima of Brazil (Med. Times and Gazette, Mar. 6th,) 
suggested that the substance known’ as Goa Powder in India 
was probably identical with the Araroba or Arariba (tawny- 
coloured powder) of the natives of Brazil, called by the Por- 
tuguese Pu’de Bahia, or Bahia powder, from its being obtained 
from that province. Dr. Da Silva Lima also stated that it 
was the produce of a leguminous tree, and had long been in 
use in the Brazils as a remedy for Herpes circinatus, chloasma 
and intertrigo., Shortly before this, Dr. Fayrer of Calcutta 
(Med. Times and Gazette, Oct. 24th, 1874,) had drawn the atten- 
tion of the Medical profession to the value of Goa Powder made 
into a paste with vinegar or limejuice as a remedy for the 
skin diseases already mentioned, and his article appears to have — 
attracted Dr. Da Silva Lima’s attention to the subject. Mr. 
_E. M. Holmes (Pharm. Jour. (3), V., 801,) stated that — 
the wood found in Goa Powder was very similar to that of 
_Cesalpinia echinata, Lam., but J. L. Macmillan pointed out 
that this wood yields its eclpertile matter to water, while 
' Araroba does not. In 1878, C. Liebermann and P. Seidler’

mainly a hitherto unknown compound, 0°°H*°O", for which — 
they retained the name proposed by Atifield, 
The bo source of Araroba was datetbinnd in 1879 
(Pharm. Journ. (3), X., 42,) to be Andira- Araroba, Aguiar,

known as Angelim amargoso. ‘The Araroba is contained in the
