Letter from Joseph Larmor, on a paper 'An enquiry into the nature of the relationship between sunspot frequency and terrestrial magnetism' by Charles Chree to the author Sectional Committee: Physics and Chemistry 'The reports on you Magnetic paper have come in, and will I hope be dealt with by the Physics Committee on April 21. As they raise points of some difficulty, I do not doubt that the Committee would be glad to hear any brief remarks you can send them with regard to the criticisms of which I enclose a copy [not attached]. Very truly yours (sd) J. Larmor' [Published in the Philosophical Transactions A, 1904]. March 1904
