Leonard Darwin’s illness.
William Darwin and the bank.
Beginning to make out a marvellous case of trimorphism.
Would be pleased to have third edition of Origin.
Is unwell and dreads the winter.
Lythrum. Wants to examine fresh flowers of Lythraceae. Lythrum salicaria has interested him very much.
Microscopes.
Asks whether JDH can think of plants that have different coloured anthers or pollen in same flowers (as in Melastoma) or on same and in different plants as in Lythrum. Would be a safe guide to dimorphism.
Observation of action of pollen in Linum grandiflorum.
On microscopes.
Cannot remember any plants but Melastoma with different coloured polliniferous anthers.
JL’s Swiss tour with Tyndall and Huxley.
Lake-habitations.
Sends his paper [on glacial lakes, see 3450]. Falconer attacked it. Falconer thinks Himalayas confound the theory, but Hooker writes that it explains the absence of lakes there.
Their enumeration [of forms of Lythrum?] is invaluable. He will write later to explain what he is trying to prove about Lythrum through laborious crosses.
Asks for flowers of both forms of Hottonia to measure pollen and compare stigmas.
