To William Lonsdale 3 August 
Not being aware of one of the rules of the Society, I omitted to ask, during the last Council day, permission to withdraw the abstract which I read on my views concerning coral Formations.1 Being engaged in drawing up an account of the Voyage of the Beagle with Capt. FitzRoy, who wishes the principal results to be given, I am now very anxious to make this request to the Council
Dear Sir | Yours very truly | Charles Darwin August 3d. then 36 Grt. Marlbro’ St.—
Asks to withdraw abstract of his paper on coral formations ["Elevation and subsidence in the Pacific" (1838), Collected papers 1: 46–9].
