Asks about proportions of male to female insects.

CD is much interested in FB’s remarks in Land and Water on the apparent excess of male trout over females and asks for further information on other fish, birds, and domestic quadrupeds.

Asks whether mane in male of Macacus silenus protects it from bites or is merely ornamental.

CD thanks BJS for photographs of Jemmy [Button]’s son

Does he know anything about male seals fighting?

Bird specimens collected by Capt. P. P. King eventually went to British Museum, but many specimens were incorrectly marked.

CD sends thanks for information; he will write to Mr Bush.

In relation to the fecundation of ova CD adds that he has compared the use of very little pollen against an immense supply; found no difference in number or weight of seeds or in their germination.
