Report on the Chemical Exammation of several specimens of 
Salt from the Loonar Lake in the Deccan, by J. E. Mayer, 
Professor of Chemistry y Madras. 
Qualitative Examination of Salt No. 1 " Dulla." 
A portion, not weighed, treated by dilute sulphuric acid gave off 
a very large quantity of carbonic acid, leaving a notable portion of 
impurities undissolved, consisting of dirt, earth and some organic 
matters ; these were separated by filtration. A portion of the fil- 
trate ascertained to be acid, was then treated by solution of nitrate 
of silver, a copious white precipitate was deposited, showing the 
presence of chlorine. A second portion of the filtered solution 
was neutralized by solution of ammonia, iron and alumina were 
thrown down in small quantity : the precipitate was separated by 
filtration; to the filtrate, solution' of oxalate of ammonia was add- 
ed, white precipitate took place ; this was separated by filtration, 
and to the filtered solution, phosphate of soda was added, a small 
crystalline precipitate occurred. 
A fresh portion of salt taken and tested by the blow pipe for 
the presence of soda, gave the characteristic flame ; the only base 
that could be left being potash, it was passed over (as if present it 
could only be in small quantity) till the quantitative examination 
was carried out.
