The function of bladders in Utricularia is not to float the plant.
Has read correspondent’s notice on bent cleavage. Refers him to observations on the same fact in South America, p. 160. CD has also suggested a conjectural explanation.
Is honoured by his election to the Philosophical Club [of the Royal Society].
Will forward JD’s paper to the Royal Society ["On the ova of salmon", Philos. Trans. R. Soc. Lond. 146 (1856): 21–9].
Discusses JD’s paper ["On ova of salmon"]. His experiments are of particular value regarding power of dispersal and geographical distribution and would make of them a very different subject. Hopes JD can test again the tenacity of life of non-developed ova being less than that of those fully developed – a result which surprised CD.
Makes arrangements to call.
Arranges to call on WRG.
CD finds JT’s discourse "grand and most interesting" [On the scientific use of the imagination (1870)]. Flattered by what JT says about him.
He is "a rash man to say a good word for Pangenesis for it has hardly a friend among naturalists".
CD is much struck with what JT says about "pondering" and delighted by his "as if" argument.
Has never before noticed with care the markings on finger-ends. Compares them to the complex whirl-pool patterns of human foetal lanugo.
Does not think WRG’s theory [about ridges of skin on palm and finger-ends?] will hold.
Does not believe the beard in monkeys and goats could be protective like the lion’s mane.
Thanks him for fact about setters.
Is perplexed about the reported milk secretion in pubescent boys.
If the Memorial concerning Joseph Dalton Hooker’s dispute with Acton Smee Ayrton was sent to Down, there will be a delay in its return. He has discussed the matter with Mary Catherine Stanley (Lady Derby).
Thanks for the three essays: although they are beyond his scope, they seem to him very interesting.
