Letter from P [Pieter] Zeeman], Zonnehof, Huis ter Heide, Utrecht, to Sir Joseph Larmor He expresses his thanks for the hospitality shown to him during his recent visit to Cambridge. He is now in a country cottage with his family, some books, and a telescope which has the same magnification as the one used by [Christiaan] Huygens in discovering the rings of Saturn. They are making amateur observations of the planet. He thinks Larmor will have received volume fifteen of the complete works, with the tract on Saturn. 24 August 1925
