Summary

Thanks FD for seeds of Canna.

Still thinks it would be worth FD’s while looking at the fertilisation of Lotus; does not think Frank Darwin has exaggerated the novelty of the contrivance.

Summary

Thanks FD for his three publications.

CD is pleased that FD has discussed Pangenesis, although he does not favour the hypothesis. Will seek English publisher.

Summary

Discusses role of insects in crossing varieties of Lathyrus odoratus and other species.

Comments on Hermann Müller [Die Befruchtung der Blumen (1873)],

and Anton Kerner ["Die Schutzmittel des Pollens", Ber. Naturwiss. Med. Ver. Innsbruck, 3 (1873): 100–68].

Admires FD’s work on anemophilous plants.

Summary

Thanks RC for his kind note. It was only Climbing plants for which he wanted the proofs to have wide margins. Wishes he understood more about printing. It would be a great convenience to authors if exterior margins of proofs were broad.

Summary

Praise of CD. Acknowledges his indebtedness to CD for defining the subject of plant fecundation.

Expecting CD’s work on the effects of cross-fertilisation.

CD has put him in touch with George Bentham.

Summary

Comments on Hermann Crüger’s paper, sent by CD, on fertilisation of orchids [J. Linn. Soc. Lond. (Bot.) 8 (1865): 127–35].

Observations on dichogamy in grasses (wheat, rye, barley).

Has not yet read CD’s reply to his article on Pangenesis [Collected papers 2: 158–60].

Summary

AM discusses his new journal [J. Travel & Nat. Hist.] of which general opinion seems to be favourable. Has room for the occasional contributor, if CD knows of any.

Summary

Cautions FD about fluid in labellum of Coryanthes.

T. H. Farrer is enthusiastic about FD’s papers.

Believes humming-birds fertilise many American flowers.

Mentions his reply to FD’s criticisms ["Pangenesis: Mr Darwin’s reply to Professor Delpino", Sci. Opin. 2 (1869): 426; Collected papers 2: 158–60].

Suggests that FD study fertilisation of Gramineae.

Summary

Apologises that he cannot supply any maize seed.

Summary

Has become Professor of Botany at Genoa.

Offers to send his paper on the necessity of out-crossing.

Summary

Looking forward to publication of Insectivorous plants, which he will review.

Paul Mantegazza has criticised FD on insectivorous plants

and CD on sexual selection; FD maintains dichogamy in plants supports sexual selection.

Summary

Thanks for ‘Die Schutzmittel des Pollens gegen die Nachtheile vorzeitiger Dislocation und gegen die Nachtheile vorzeitiger Befeuchtung’ (Preventive measures of pollen against damage by premature dislocation and moistening; Kerner 1873) and several pamphlets.

Summary

Will send FD’s work [Studi sopra un lignaggio anemofilo delle composte (1871)] to Nature for review.

CD’s health has been poor all summer – he doubts that he will ever "have the strength to publish on Variability under a state of Nature".

Hopes to publish on cross- and self-fertilisation next summer.

Encloses his photo and asks for FD’s.

Summary

Sends last part of his book [Ulteriori observazioni sulla dicogamia (1868–74)] [osservazioni!?] and describes contents.

Summary

Left the Garibaldi at Rio de Janeiro.

Phylogeny of aphids.

Summary

Sends his new work, Ulteriori osservazioni sulla dicogomia pt 2, fasc. 1.

Has found no nectar in Orchis morio or O. maculata in Italy and has seen no insects visiting the plants.

Gives his observations on cross- and self-fertilisation in cereals.

Summary

Comments on CHB’s book [Experimental researches on catarrhus aestivus – hay-fever or hay-asthma (1873)].

Explains that some pollens are wind-blown while others depend on insects for dispersal. Effect of pollen on skin and mucous membrane astonishing. Sends a book [M. Wyman, Autumnal catarrh (1872)].

Summary

Sends information on Lathyrus odoratus, Phaseolus multiflorus and Pisum sativum.

Summary

Thanks CD for his orchid paper ["Fertilization of orchids", Collected papers 2: 138–56]. Comments briefly on orchids.

Discusses moths in which the wing underside is the most brightly coloured, and relates his observations on sexual selection by a moth, Syntomis.

Summary

Fertilisation of barberries.

Passiflora.

Is continuing his experiments on the comparative growth of crossed and self-fertilised plants.
