By the kindness of Sir William Ramsay and Mr. H. E. Watson we have had an opportunity of measuring the refractive index of neon with a large quantity of the gas (300 c. c.) which had been carefully purified by Mr. Watson. Subject to small corrections which he has not yet completed, the weight of 1 litre of the gas was 0·9005 gramme at 0° C. and 760 mm. pressure in London. From 11 experiments which hardly varied by 1 part in 500 we find the refractive index at 0° C. and 760 mm. for the green mercury line (λ = 5461) to be 1·00006716 or, doubling for comparison with diatomic gases, 1·0001343.
