Summary

Huxley has answered Kölliker in Natural History Review [(1864): 566–80].

CD is correcting two of Scott’s papers; is convinced primrose and cowslip are two good species.

Summary

Morphological differences only partly define species; physiological differences, e.g., incompatibility results in Primula, are far more interesting.

T. Thomson’s review of Agardh’s muddled book ["Agardh’s classification of plants", Nat. Hist. Rev. (1864): 536–51].

Summary

To Lyell’s chagrin, CD has come round again to A. C. Ramsay’s glacial theory.

On primrose and cowslip, CD maintains they are good species, notwithstanding Scott’s work.

CD defines species by power of remaining constant for a good long time and showing appreciable amount of difference from close species.

Summary

Comments at length on Ramsay’s glacial paper ["On the erosion of valleys and lakes", Philos. Mag. 4th ser. 28 (1864): 293–311]. Prefers it to Tyndall, but unconvinced about sea action and unwilling to grant that ice power sculptures the totality of landscape.

Unwilling to support Wallace for Royal Medal.

Herbert Spencer’s noisy vacuity.

Garden varieties that are constant and infertile with parent deserve to be called species.

Scott ineligible to be Linnean Society associate because he is not in England.

George Busk’s incoherent talk on Gibraltar cave fossils.
