Asks about insects and seeds on leaves of Pinguicula.
Thanks CHM for a report about birds of the United States [see 9461].
CD is deeply pleased by AG’s article on him in Nature [10 (1874): 79–81].
Is preparing book on "Drosera and Co." for the printers. Reports observations on digestion in Drosera and Pinguicula.
Discusses effects of water on movement of insectivorous plants.
Has just found that Pinguicula can digest albumen.
Asa Gray writes that Sarracenia secretes trail of fluid to attract insects [see 9455].
Thanks ID for interesting and curious facts but doubts that he will have time to enter more closely into the subject of the intellect of animals.
Nothing would give CD more "pleasure & interest" than to see ID’s country, "now so great & destined to be so much greater", but he is quite incapable of "so great an exertion as crossing the Atlantic".
Profoundly grateful for AG’s article in Nature; he is especially pleased by what AG says about teleology.
Asks what proportion of leaves of Pinguicula have insects adhering to them. Also, whether seeds of any plants ever adhere to the leaves, and in what situations does P. vulgaris grow.
Did not know cabbage contained so much nitrogen.
Pinguicula more excited by seeds than Drosera. Asks for information about Pinguicula.
Asks name of weed.
Asks to borrow Utricularia plant.
Comments on GHD’s paper ["Marriages between first cousins in England and their effects", Fortn. Rev. n.s. 18 (1875): 22–41]. Hopes it will be published and read at the Statistical Society.
JSBS’s article in Nature ["Venus’s fly-trap", 10 (1874): 105–7, 127–8] could not have been better done.
Has found another plant, Pinguicula, which can catch and digest flies.
Did not know Duval-Jouve was an evolutionist.
Delighted at JTM’s success with spiders.
On JTM’s experiments with acids on seeds.
Asks JVC if he can provide introductions in Leipzig and Dresden for his son George.
Has not yet received any revised sheets of Descent [2d English ed.].
Hopes a printing of 2000 copies [of Descent, 2d ed.] will be safe. Regrets price must be 12s. He is sure it is much improved.
Asks for living plant of Utricularia and information on Pinguicula lusitanica. Gives notes on habitats.
Thanks for fibrin. Drosera and Pinguicula dissolve it thoroughly.
Will soon publish on insectivorous plants; asks for a particular observation on Dionaea.
Has found Pinguicula excited by bits of leaves; appears to digest leaves and seeds. Plant not only insectivorous but graminivorous. Asks WTT-D to identify seeds.
Remarks on his work on Pinguicula. Notes its digestive power; it absorbs nutritious matter from leaves and seeds as well as insects.
Sends observations of poison acting on glands of Drosera. Poison acts as a stimulant to protoplasm. Very remarkable that poison acts so differently on the cilia and protoplasm of Drosera.
Wants particularly to know whether seeds or leaves of other plants are ever found adhering to the leaves of Pinguicula. Observations would perhaps best be made in a month or two.
