Scottish chemist (1852-1916) who discovered the noble gases and won the 1904 Nobel Prize in Chemistry. ALS, one page both sides, 4.5 x 7, Beechcroft, Hazlemore, Bucks letterhead, July 9, 1915. Letter to English physiologist and neurologist Henry Charlton Bastian, in part: "Usually, 'iron sulfate' is a ferrous salt, FeSO4. 7H20. As you may remember it is green coloured crystals. It is likely that that is what you are using, as your solution is green. Ferric sulphate is not so commonly sold; it is Fe2 (So4)3, & is a nearly white powder. The deepening of the colour of your solution is due to oxidation; 2 Fe=SO4 + O (dyad iron) = O—Fe=SO4 [and] Fe=SO4 (triad iron). I am surprised the solution is not turbid (unless it is acid) for the basic ferric sulphate is pretty insoluble. It may be your granular yellow deposit. We have been deprived of our car for over a month; and our chauffeur went…in January. But we hope to make an excursion some day soon to see you all. We were to have had our car back last night, but it is not here yet." In fine condition.
