Thanks for note. Believes agreement with Henry Colburn does not cover 2d ed. of Journal of researches. Regrets Murray’s Colonial Library series will require one-fifth reduction of text; will consult Lyell on how to reduce scientific part. Prefers that JM consult with Colburn, but in case he declines, encloses draft of letter he would send to Colburn. Anticipates co-operation of Colburn, as he has paid CD nothing for 1st ed. of Journal.
