Indian Steel or Wootz, is very lightly prized in Europe, and the ob- 

 jection to it is the great expense required to fuse it in England, in con- 

 sequence of the imperfect state in which it is manufactured by the 

 Native workmen, who are ignorant of the principles of the process. 



Sulphuric Acid may be made in India much cheaper than in England, 

 because the Sulphur and Saltpetre required are both mineral products 

 of this country, and of course its application in the manufacture of Nitric 

 Acid, Muriatic Acid, and Acetic Acid. In making Chloride of Lime for 

 use in bleaching, in dyeing, &c, and numerous others will follow of 

 course. 



Pyroxalic Spirit is another product in the decomposition of wood, 

 which fetches a high price in England, and might be useful for producing 

 light in India, where wood is so plentiful and cheap. 



Acetate of Lead is another form in which Acetic Acid might be 

 combined as an article of commerce, (vide process.) 



Acetate of Alumina is another form in which Acetic Acid might 

 be combined as an article of manufacture of great request in dyeing. 



Phosphorous is a product which might be made in India, and afford an 

 instance of the application of Sulphuric Acid. 



Citric Acid is very expensive in England, being made exclusively by 

 decomposing an Alkaline Citrate, but which might be cheaply made in 

 India from Limes. 



Citrate of Soda or Lime might be cheaply made in India, (vide pro- 

 cess), and as the fruit is so abundant and cheap, could be made at less 

 expense than Tartaric Acid. 



Vinegar cheaply and readily made by the fermentation of a solution 

 of sugar, and as the sugar is so cheap in India, the coarse inspissated 

 juice selling in many places for eight annas per maund, which yields by 

 fermentation — parts of vinegar of the common strength, it can be 

 made for — a gallon. 



The Pipe Clay of Arcot, and probably of other parts, affords the means 

 of making Pottery of the finest kind in India. 



The Kaolin of Mysore affords the means of making the very finest 

 kinds of Porcelain at little expense, and may be more generally employ- 

 ed in making crucibles and melting pots for metals, or fire bricks for 

 lining furnaces. 



Glass also may be an article of manufacture, as the finest kinds of
