CD counters Thiselton-Dyer’s objection to protoplasmic filaments of Dipsacus protruding beyond cell-wall, as Frank’s paper claims, by citing white "blood cells passing through vessels".
Has received Moseley’s collection of photographs.
Discusses spider specimens.
Thanks GBE for his essay on the placenta [Sull’unità del tipo anatomico della placenta nei mammiferi e nell’umana specie (1877)].
Apologises for sending wrong Cross and self-fertilisation erratum. The error is on p. 191 (where "cross-seeds" appears, it should read "self-fertilised"). There is no error on p. 275.
Asks EH to make a small correction in his translation [of Cross and self-fertilisation].
Baillière wishes to bring out a French translation of Coral reefs; CD requests their co-operation.
Leucosmia burnettiana is in all probability dimorphic. Thinks Gilia is truly heterostyled and Phlox subulata was, perhaps, once heterostyled. Has good evidence of heterostyly in 39 genera from 14 families.
Thanks MN for essay ["Die Congerien", Abh. Geol. Bundesanst. Wien 7 (1875)]. It is the best case CD has met, showing "direct influence of conditions of life on the organization". A. Hyatt has come to same conclusion: that closely similar forms may be derived from distinct lines of descent. CD did not emphasise in Origin the direct action of environment on modification of species; most of the best evidence has been observed since its publication.
Warm thanks for CC’s letter. CD needed no word from CC to be convinced of his high opinion.
Thanks for CHB’s essay [New observations on hay-fever (1877?)]. The calculation of the weight of pollen-grains is wonderful. Suggests he consult Cross and self-fertilisation, pp. 376, 405 for information on this subject.
Enquiring about cleistogamic flowers of Oxalis.
Asks when his waggonette will be finished.
Discusses possible cleistogamic flowers in Oxalis.
Thanks for Chauncey Wright’s work [Philosophical discussions (1877)].
Gladstone visited recently, and they discussed the future role of the United States as a world power.
Thanks for account of his work. Cannot read Dutch, but son has translated it.
Thanks for album sent by PH’s countrymen.
Sends an informal title-page [for Orchids, 2d ed.].
Appreciates the condolences for Frank [on death of his wife, Amy].
CD apologises for his burdensome request of Oliver.
Criticises JDH’s notice on Forsythia, which JDH said was dioecious. Forsythia sent to CD from Kew was heterostylous.
Has received the sheets of EG’s Spanish translation of Origin. Regrets that he cannot undertake to read them because of his health, over-work, and having forgotten much of the language. What he has read seems clearly expressed.
Evidence for inheritance of constitutional diseases like scrofula so good that it seems rash to breed tainted animal.
Experiments given in Cross and self-fertilisation show that evil of inbreeding follows from near relations possessing closely similar constitution.
Size and vigour increased by breeding plants and animals from ancestors that lived some generations under different conditions of life.
Thanks for EK’s book [Werden und Vergehen (1876)].
Regrets he cannot write for EK’s journal, but his son, Francis, may do so.
Suggests EK as editor urge on readers [of Kosmos] the investigation of the causes of variability; why, for instance, do wild Pampas cattle change colour when domesticated? Thinks experiments and observations on recently domesticated animals and cultivated plants would throw light on the subject.
