To William Ogle 9 November 1870
Summary
Has read WO’s paper [see 7361] with great interest. If WO’s views are confirmed he will be able to explain many odd little details about the colouring of animals.
Can WO observe if the platysma myoides is brought into strong action in people suffering from severe dyspnoea?

To William Ogle 17 November [1870]
Summary
Thanks WO for information on platysma, which he did not know could be brought into voluntary action. Is coming to believe it has nothing to do with expression.
On the relation between white colouring and susceptibility to poisonous plants, CD suggests WO send his paper to J. Wyman and propose he investigate whether white as well as black pigs will eat paint-root.

To William Ogle 17 December [1870]
Summary
Thanks WO for valuable letter. Feels he need not trouble any more about platysma. If WO ever sees someone suffering great fear, CD asks him to observe the neck.
Hopes to visit WO when next in London.
