To T. H. Huxley 13 [December 1856]
Summary
Pleased by what THH says on cement glands and organs in higher Crustacea. Content to be moderately right.
Hopes THH will dissect the Conchoderma.
Asks for cases of organs in which there is no apparent transition from other organs or in which transition can be shown in an unexpected way and for instances of odd and inexplicable connections between parts, such that if one part varies the other varies also.
