MANGANESE DEPOSITS OF INDIA: ECONOMICS. [pART 111 : 
As regards phosphorus, the figures for the Indian ores are rather mis- 
leading ; for an examination of the analyses from which these figures 
have been taken shows that the ores consist of two different varieties, 
The majority of analyses are typical of the ores of the Central Provinces, 
whilst four of them probably represent ores from the Vizagapatam 
district. I have accordingly separated them into two groups, of which 
the limits and averages are given in tables 74 and 75. From these 
figures it will be seen that the Central Provinces ores average 0*096% and 
the V^Lzagapatam ones 0"291% in phosphorus.
