Pages 17-18. The only published analyses of the iron ores of Cuttack are those 

 given by Mr. Piddington in the Journal of the Asiatic Society of Bengal, 1855, p. 708. 

 Two varieties, forwarded by Mr. SamueUs, were experimented on. One, from Kmikerie, 

 of " ochrey red iron ore," yielded a per-centage of peroxide of iron equivalent to 46'8 

 per cent, of metallic iron ; the other, from Paleyra, is stated to be a " mixture of the 

 hydi'ated carbonate of the protoxide of iron, with a large proportion of earthy matter," 

 although, by some typographical error I presume, the details of the analysis do not 

 show any carbonic ai;id whatever. It yielded, according to Mr. Piddington, 60"60 

 per cent, of protoxide of ii'on, equivalent to 47" per cent, of metallic iron, with some 

 manganese.
