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.

Thanks JSH for Anacharis which is flourishing.

P. H. Gosse told him he had several sea animals and algae living in artificial sea-water for over 13 months.
