SULPHUE.

of manufacture explained, possibilities of improvement therein 
suggested. 
Its use in the production of soda, chlorine, soap, candles, 
phosphorus, lucifer matches, lighting oils, and liquids and in the 
manufacture of superphosphate described, as well as its employ- 
ment in the extraction of metals from their ores, and the prepara- 
tion of costly dyes and most valuable medicines. 
As a remarkable consequence of the recent greatly extended 
use of sulphuric acid for the manufacture of superphosphate, the 
Longmaid process for the extraction of copper from its ores, has 
been so extensively brought into operation, that in 1870 more 
than 400,000 tons of sulphur ores had been operated on, and the 
Tyne district has become an important copper smelting district. 
By careful application of the knowledge of the relationship of 
sulphur to the many constituents of ores, it is now being attempt- 
ed in Devon and Cornwall to utilize very large quantities of ores 
hitherto valueless, by the combined use of the Longmaid process 
and the new revolving calciner, so that instead of as hitherto one 
only of the constituents of an ore being rendered available, they 
may all be made so, thus bringing to maturity plans long since pro- 
jected by the lecturer, for making scientific principles the basis of 
all metallurgical operations.
