Letter from J Theo [John Theodore] Merz, The Quarries, Newcastle upon Tyne, to [Joseph] Larmor He received the reprint of [James Clerk] Maxwell's classic treatise with pleasure. His inablity to read with his own eyes will prevent him from appreciating the additional original matter, but he has lent the book to a friend who will relay Larmor's remarks. Fundamental notions have changed greatly since the beginning of the century. 25 September 1920
