Summary

Encloses Pinguicula specimens.

Believes she has found a new species of water-lily.

Summary

Thinks Frank and he have worked out Pinguicula well and they long to attack Utricularia. Tried several plants with sticky glandular hairs; some few absorb ammonia, but the greater number do not. If JDH sends plant or seed of Lychnis CD will examine it to see whether it catches many flies. Asa Gray has written him much about Sarracenia, with a specimen showing the splendid dodge by which ground insects are enticed up and then drowned. Describes how it may be investigated, to see whether it absorbs decayed matter from flies, or ammonia thus generated.

Summary

Returns Webb and Berthelot, Îles Canaries; Géographie botanique [1840].

Describes work on 3d ed. of Anthropogenie.

Summary

Acknowledges presentation copy of Insectivorous plants.

Studying Drosera on vacation in Bohemia. Thinks CD has erred in considering "aggregation" to have occurred in the protoplasm. Suggests it is result of exosmosis of vacuole.

Summary

Comments on AW’s essay [on "Axolotl", Z. Wiss. Zool. 25 (suppl.) (1875): 297–342] with respect to evolutionary reversion. Peloric flowers must also be considered reversion.

Summary

Thanks for answer to racehorse query;

would be grateful for correction of any errors in Variation.

Summary

Thanks for interesting letter on climbing plants.

FM’s view on Anelasma seems probable.

Difficulty quoted by FM from A. Agassiz on embryology of Echinodermata is quite beyond CD.

Summary

Proposes to write on Sarracenia ["Carnivorous plants of Florida", Harper’s New Mon. Mag. 53 (1876): 546–8, 710–14].
