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.
Delighted to hear that JD’s research is continuing. CD has heard that JD’s paper will at last be published. He is flattered by the form [as a letter addressed to CD] of communication. [See 1651a and 1819a, published in Phil. Trans. R. S. 146 (1856): 21–9 and Proc. R. S. London 8 (1856–7): 27–33.]
Responds to CD’s letter. The ova of Salmonidae exposed to air, if kept moist, will stay alive up to 72 hours.
On the ova of the salmon in relation to the distribution of species.
On the vitality of the ova of the Salmonidae at different stages of development.
