Thinks Bates’s paper on mimetic butterflies ["Contributions to an insect fauna of the Amazon valley", Trans. Linn. Soc. Lond. 23 (1862): 495–566], is very good; would appreciate an article on it from CD ["On mimetic butterflies", Nat. Hist. Rev. (1863): 219–24; Collected papers 2: 87–92].

H. W. Bates’s paper; CD will review it. ["Mimetic butterflies" (1863), Collected papers 2: 87–92.]

Thanks CD for agreeing to review Bates’s paper for Natural History Review.
