To James Crichton-Browne   2 November [1871]1

Down,

Nov. 2,

My dear Sir

I have some reason to believe, but have found it extremely difficult to get observations made, that the Platysma is very apt to contract during a rigor or shivering fit.2 If you have ever the chance to observe a patient in this state, will you kindly observe the muscle. I am just recommencing on my essay on Expression.3

Yours very sincerely | Ch. Darwin.
