Summary

Thanks WCW for sending his lecture ‘The dawn of animal life’, which seems "a wonderfully clear & interesting sketch of the lower organisms".

Summary

Specimen ruined in transit.

Drosera spathulata modified form of D. rotundifolia.

Sends reference regarding Bolbophyllum.

Summary

Thanks WCW for sending specimens. Drosera spathulata must be descended from some form like D. rotundifolia.

Summary

Thanks WCW for his article ["Microscopical objects found in mud of Levant", Mem. Lit. & Philos. Soc. Manchester 2d ser. 8 (1848):1–128]. Comments on it; offers to send Ascension Island specimens. Urges WCW to re-examine coal-beds for Infusoria to determine whether intervening beds were deposited by sea-, brackish, or fresh water.

Summary

CD cannot find the lagoon-island mud that WCW asked about, but he sends other geological specimens he hopes will be interesting.

Summary

Thanks him for plant specimens.

Asks about sowing Drosera seeds.

Summary

WCW’s specimens are interesting, but CD thinks the slowness of the change might have been expected.

Summary

Receiving deputation gave CD pleasure.

Summary

Does not remember where specimens came from. CD picked fossils most likely to contain Infusoria. Discusses composition of Tertiary strata of South America from which they came. Questions WCW’s statement that they contained siliceous matter.

Summary

Thanks CD for receiving the Yorkshire Naturalists’ Union’s deputation.

Summary

Sends plant specimens for CD’s examination for genetic affinity with Drosera rotundifolia
