Thanks for a copy of Insectivorous Plants.
Thanks for a copy of Insectivorous Plants.
At last, Expression is beginning to sell again.
Cooke has not yet decided on number of Variation [2d ed.] to print.
Asks GHD to calculate average or mean heights of crossed and self-fertilised plant species.
No summary available.
Provides CD with a method of obtaining a numerical ratio that expresses the superiority in heights of crossed plants to self-fertilised plants.
No summary available.
Has confirmed CD’s observations on Drosera.
Asks whether CD agrees that it is "no longer a fact" that the bladders of Utricularia vulgaris enable the plant to become lighter for fecundation and heavier when that act is accomplished. Plans to undertake further observations, under very high-powered microscopes, of mechanism of digestion.
Bug on Tilia, cited in Variation, was Cimex apterus.
He has confuted Descent.
Enclosures announce his cures of potato blight, epilepsy, etc.
Accepts WR’s offer of copies of the Garden for the next half-year.
CD has read all of WHD’s and J. J. Drysdale’s papers [on spontaneous generation, monads, and the origin of life] and finds them the best work on the subject.
The function of bladders in Utricularia is not to float the plant.
Two photographs of T. W. Clarke, Jr, aged three, offered as examples of expression.
Thanks FG for his report [on the statistical validity of CD’s experiments; see Cross and self-fertilisation, pp. 16–18]. Discusses FG’s comments, his own experiments, and the means by which the results may be analysed.
Sends copy of Arabische Korallen [1876].
Comments on reception of his paper on "Gastrula" [see 10012].
Has sent his paper on Echinoidea [see 10373] as a token of his veneration. He tried to address the confusion in knowledge about the different parts of the exoskeleton of the Echinodermata by tracing certain relations of homology not previously noticed. Much more work is required.
JDH informs Asa Gray that he is writing to Waldo Ross to thank him for a barrel of apples. JDH has received Gray's letter of 6 Dec [1875] & thanks him for a second copy of AESTIVATION AND TERMINOLOGY. JDH agrees with Gray regarding the importance of keeping [herbarium] material out of bad hands. He praises Decaisne's Pirus essay & Gray's notes in it, but notes that [Henri Ernest] Baillon has inserted a mistake into Decaisne's work; regarding the position of ovules. JDH dismisses Baillon's HISTOIRE [DES PLANTES] & calls his work on Phytolacceae a poor rehash of a bad work by Moquin-Tandon. JDH is puzzled what to do with Stegnosperma. He & George Bentham[GB] have decided to keep up Paronychieae [in GENERA PLANTARUM] & put Limeum & Gisekia [Gisechia] into Mollugineae. JDH has done Nyotaginea & had a dreadful task with Mirabilis Oxybaphus & co. But with GB's agreement kept Mirabilis for the big flowers & Oxybaphus for the small as a poor compromise. He offers to send Gray the glossary. He thinks Gray's varieties of O. cervantesii are both good distinct species. JDH is now working on Paronychieae & GB on Labiatae. Acanthaceae is being printed, to be followed by Verbenaceae. In response to Gray's entreaty JDH states he cannot visit him in the USA as he has 6 children to deal with. Hardy will go to New York in July & JDH would like to visit Gray at that time. Parish lives up to expectations. Diggs has given another grant to print the CATALOGUE OF SCIENTIFIC PAPERS for 1863-73. GB has recovered from a cold. Munro has settled near Taunton. [Thomas] Thomson has been very ill, he lives near Maidstone. [Charles Robert] Darwin is well, for him.
Reports on the tendency of the normally fruitless Convolvulus arvensis, to form fruit when roots are cut and plant is in danger of dying.
