Thanks for a correction. Hopes AG now has all the sheets of Cross and self-fertilisation.

Plans to republish his paper on dimorphism with additions [Forms of flowers]. Is convinced it is necessary to compare pollen-grains and the state of the stigma to recognise dimorphic plants. Requests specific plants to test for dimorphism and would welcome examples from any family in which he has not encountered dimorphic species.
Thanks for information about Hottonia.
Has found dimorphism in Forsythia.
Considers AG’s arguments on different terms for dimorphism, but cannot change to using the proposed new term [see 10699].
Asks AG not to send his rare specimens [of Leucosmia].
Is glad of the notice about black pigs.
Has great faith in Jeffries Wyman;
thinks A. R. Wallace founds his speculation on a feeble basis.
Thanks AG for card about Pontederia.
Asks for specimens of Phlox subulata and Gilia aggregata to check for dimorphism.
JDH is busy working on a new edition of his STUDENT'S FLORA OF THE BRITISH ISLES he compares the delineation of species in the flora to that in Asa Gray's MANUAL OF THE BOTANY OF THE NORTHERN UNITED STATES. JDH consults Gray on whether Gymnosperms should be a subclass of Dicotyledons or a group equal to all other Phaenogams? Joseph Decaisne, Gray & JDH favour the former position, Daniel Oliver & William Thiselton-Dyer the latter. Gnetum, esp. Formation of the embryo, will be key in determining the correct arrangement. JDH has sent the corrected SCIENCE PRIMER: BOTANY to the press, he would find such works easier to write if he also lectured. Life with his new wife Hyacinth Hooker is good & his future looks bright though sad times behind him make him doubt its security. JDH's sister Mrs Elizabeth Evans-Lombe, née Hooker is suffering less from neuralgia & melancholy. George Bentham is well. Oliver is working on the African flora, & Moore[?] is working on grasses. Asks if Charles Sprague Sargent can send American Southern Bamboo.
Praises AG’s abstract of Cross and self-fertilisation [Am. J. Sci. 3d ser. 13 (1877): 125–41].
Hopes soon to finish with dimorphic plants.
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.

Sends an informal title-page [for Orchids, 2d ed.].
Appreciates the condolences for Frank [on death of his wife, Amy].

C. E. Bessey’s case [see 10969] came too late, as the sheets had been printed, but CD thinks it should be carefully investigated as a possible case of incipient heterostyly.
Is trying to make out the function of "bloom", the waxy secretion on leaves and fruits.

Thanks for AG’s review of Forms of flowers [Am. J. Sci. 3d ser. 15 (1878): 67–73].
Thomas Carlyle’s letter about CD was a forgery.
Gives Hermann Müller’s observations on Valeriana dioica.
Is unsure about function of "bloom"; are glaucous plants more or less common in arid parts of U. S.?
Observations on heliotropism.
Thomas Meehan reports that Linum perenne is self-fertile; CD thinks that he has mistaken the species.
