manner connected with the presence of salt. The wells in 
British Burma are of much more importance, a well in Eastern 
Baronga having at one time yielded 1000 gallons a day. 
The deposits of sulphur in India are of little importance, and 
are situate chiefly in localities difficult of access. Arsenic and 
bismuth are also found, but sparingly. Concerning the latter 
metal we find the curious remark that it enters into the compo- 
sition of mordants for calico-printing. We are not aware that it 
has ever been used for this purpose on a practical scale. 
An enormous lode containing antimony ores (stibnite, cer- 
vantite, and kermesite) has been discovered at Shigri, in the 
Punjab. Platinum occurs in a number of localities on the small 
scale. 
Tradition points to the existence of mercury in the Andaman 
Islands, but no proof has been obtained. 
That the ruling dynasties of Southern India at one time pos- 
sessed vast quantities of gold is beyond doubt. Whether the 
deposits have become exhausted, or whether the precious metal 
may still be obtained in remunerative quantities, will probably 
soon be decided by the operations of mining companies in the 
Wynaad and elsewhere. A number of the natives in the aurife- 
rous districts occupy themselves with gold-washing, but their 
earnings are described as generally but trifling. 
Tin is met with in remunerative quantities in the Tenasserim 
district. 
Cobalt occurs in Nepal and Burma. It is used by the native 
jewellers in colouring enamels and bangles blue, and in producing 
a fine rose-colour on gold by a process unknown in Europe, and 
preserved as a secret in certain families. 
In like manner the author works over all minerals useful in the 
arts and manufactures, pointing out where they have been dis- 
covered, or actually raised on a practical scale, and discussing 
the probability of their being made remunerative. The results 
of this comprehensive survey must be pronounced, upon the 
whole, somewhat disappointing to those interested in the pros- 
perity of India. Still it must be remembered that the Geological 
Survey of India has been able to give as yet little beyond a broad 
general sketch. Even in Britain, where explorers are a hundred- 
fold more numerous, and where they meet with so much greater 
facilities, valuable deposits of minerals are still from time to time 
discovered. It is therefore far from unlikely that such will be 
the case also in India.
