used in local industries. These consisted of spent indigo, poppy, 
tobacco and ‘‘ gada purnah ”’ (Boerhaavia diffusa, Linn.). The 
processes. They were from Burma, Murshidabad, Manipur 
(where the ash is called “ Lapee-ut”’) and a Bengal village. A 
buns was also tested. On igniting the samples and estimating 
the solubility and alkalinity they afforded the following figures :

This partial analysis of the samples exhibits an absence of 
uniformity in the composition, the chief features being the 
water-soluble matter ranging from 7:94 to 27°51, with a certain 
correspondence in the alkalinity, and insoluble silica from 22-2

was 8°75 and in No. 2, 11°5.
