Letters from Sir James Dewar to G D Liveling

The letters concern Dewar's work on the low-temperature thermoelectric properties of bismuth; detection of impurities in bismuth; the writing of joint papers with Liveing, especially on their investigation of CN band spectra; unfavourable comments on Crookes's and Ramsay's work on the argon spectrum; his own and his wife's poor health. One letter, dated 18th June 1907, states Dewar's need for radium bromide.
