Letter from [John Ambrose] Fleming, Pender Electrical Laboratory, University College, Gower Street, London, to Professor [Joseph] Larmor, Secretary of the Royal Society Fleming leaves his revised 'Note on the Theory of Directive Antennae', as Larmor had mentioned the original form was 'not sufficiently explicit', and he would therefore like to withdraw his previous note. Fleming hopes in its present form it will be published in the Proceedings. 23 May 1906
