Letter from William Huggins, 90 Upper Tulse Hill, S W [South West] London, to the Secretary [Joseph Larmor] Discussing the radium research, namely the observations of glow of the radium bromide and of the visibility of the nitrogen spectrum. Huggins has no strong opinion about the Fraunhofer lines in the corona, but thinks that [Hugh Frank] Newall underestimates the difficulty of bringing these out in the kind of light. He wishes Newall would conduct such an experiment with a spectroscope so as to bring out the H lines. 15 November 1905
