When at Jauli, in the same districc. I took a sample of the soft hematite 
being smelted there for the production of the soft iron on to which the 
Men is welded. The analysis, made by Messrs. J. & H. S. Pattinson of 
Newcastle, is given below : —

Samples taken from the rough blooms of kheri and soft iron produced from 
these ores were analysed by the same firm of analysts with the follow-

The third sample represents some round shot found amongst the 
ashes and charcoal left after the bloom has been taken out of the furnace. 
From these analyses it will be seen that the superior hardness of the 
kheri over the soft iron can hardly be attributed to the 0 -3% of mangan- 
ese it contains ; but must rather be attributed to the larger amount of 
carbon. The manganese has no doubt had a purifying effect on the kheri
