I have had my eye on Gratams observation for some time, but have had no time to repeat it. Your letter will bring me to this scratch; & it may prove a good means of separation. My impression is that argon passes through iron, but it is not proved. I think I lost a lot in using iron tubar; & I have always intended to repeat it & to use platinum, but I have not had time as yet. There is too much to do. Believe me." Card is addressed on verso in Ramsay s hand to "Anshby Esq. Grammar School". Two folds, handling and corner wear, mounting residue on verso, else good condition. On the evening of 19 April 1894 Ramsay attended a lecture given by Lord Rayleigh. Rayleigh had noticed a discrepancy between the density of nitrogen made by chemical synthesis and nitrogen isolated from the air by removal of the other known components. After a short conversation he and Ramsay decided to investigate this. In August Ramsay told Rayleigh he had isolated a new, heavy component of air, which did not appear to have any chemical reactivity. He named this inert gas "argon". A handwritten letter mentioning argon is of great rarity. COMES WITH A CERTIFICATE OF AUTHENTICITY BY ANDREAS WIEMER HISTORICAL AUTOGRAPHS.
