Thanks for sending papers by Hermann Hoffmann.
Discusses spiral cells in Drosera and Pinguicula.
Sends CD his photo
and a copy of his address at Hartford ["Change by gradual modification not the universal law", Proc. Am. Assoc. Adv. Sci. (1874) pt 2: 7–12]. Does not believe his observations are unfavourable to natural selection but feels there are other factors involved in the origin of form.
Discusses further his work on colour and sex in plants; the linking of high colour and maleness.
Will send a different Utricularia species when the seedlings are better established.
