Asks WW to alter, before printing, the passages in WW’s Presidential Address to the Geological Society [Proc. Geol. Soc. Lond. 3 (1839): 93] which pointedly allude to the delay in publication of CD’s Beagle journal; they might annoy FitzRoy, who, as Captain, has a right to first use of the papers of all officers on board.
Asks to be allowed to bring his sister to CB’s party "that she may see the World".
