Letter from T J J [Thomas Jefferson Jackson] See, Mare Island, California, to Sir Jos [Joseph] Larmor, Cambridge Feeling that Larmor is a 'good Newtonian', he sends a summary of his longer paper, drawn up for a Copenhagen meeting in August and to be published in the Astronomische Nachrichten. The mathematical part is condensed but the philosophical discussion may interest the cultivators of science at Cambridge. If Larmor should be attending the British Association meeting at Oxford, he will be able to speak on these great questions, treated from a new point of view, and he make any use of the paper he feels advisable. 10 July 1926
