Iron in Ancient India c7.s3.1

c7.s3.1

The author is not aware of my micrographic examination of the iron of the Delhi pillar or any other specimen of ancient Indian iron. The results of micrographic examination of the three specimens of Ceylon iron by Sir Robert Hadfield will prove interesting. For photographs of micro-sections the reader is referred to Hadfield's paper. We give below only the results obtained by him with respect to the iron chisel, nail and bill-hook, analyses of which have already been given.
