For comparison with the figures given in table 69 I give below in table 
71 figures, obtained from a reliable source, show- 
orefex'Scted by tte- . ^^^S" Composition of the ores that 
buyers expect to obtain when contracting for 
the purchase of various Indian ores. It will b6 seen that they agree 
very well, with one or two exceptions, with my figures given in table 69. 
The most marked exception is the Panch Mahals. My figures are probably 
lower than would be obtained in practice, because I took average samples 
from the outcrop without any selection, such as would naturally take 
place when the ores came to be worked. Some of these samples are, 
moreover, probably from parts of the outcrop that it has not been found 
profitable to work.
