Letter to the Editor: THE IRON COLUMN AT DELHI

Abstract

SIR, The occasion of the Corrosion and Metal Finishing Exhibition appears to have aroused fresh interest in the remarkable iron column at Delhi that is still, after nearly 1,700 years, in an excellent state of preservation. The Observer published a good photograph of it when alluding to the exhibition, and Sir Alexander Fleck in his speech when opening the exhibition made some interesting references to it as reported in your issue for December. Its preservation has puzzled many mineralogists and Sir Alexander did not offer an explanation, although he mentioned that he was not impressed by the suggestion that the so‐called mild climate of Delhi is an important factor in its preservation, and he referred to Desch's statement that there is a coating or fine adherent layer of slag, and to the suggestion that these metals may have been forged on stone anvils.
