Grateful for AH’s long letter and suggestions. Delighted at what he says about "complemental males". CD feared no one would believe in them but now that Owen, Dana, and AH accept them, he is content.

AH’s paper on Alcippe [Ann. & Mag. Nat. Hist. 2d ser. 4 (1849): 305–14] caused him to lose sleep over its anomalous structure.
