‘“We have had the opportunity of examining a sample of 
Kaladana resin manufactured by Messrs. Rogers and Co., 
Chemists of Bombay and Poona, which we found to agree with 
that prepared by ourselves. Itis a light yellowish friable mass, 
resembling purified jalap resin, and, like it, capable of being 
perfectly decolorised by treatment with animal charcoal.” (Op. 
eit., nd Hd., p. 449.) 
Commerce.—Kaladana is collected in different parts of the 
country; the plant is everywhere common during the latter

In the Bombay market the seeds of oo muricata, Jacq., 
imported from Persia, are much more common than those of 
the true Kaladana. They are accepted by the natives as 
Kaladana. Value, Rs. 5 per maund of 374 lbs.
