To William Ogle 17 December 
Down | Beckenham | Kent S.E.
My dear Dr. Ogle
Absence from home has prevented me from thanking you before for your last to me very valuable letter. I think I need not trouble myself much more about the Platysma.1 If you shd. ever see any one suffering great fear & can remember the point do look at the neck.— I will enquire what muscle my informant named when he spoke about the longitudinal furrows.2 I think Duchenne always speaks of transverse furrows.—3
I have just been in London for 6 days for some rest, & intended calling on you; but days so short, & not much strength for what I was forced to do, that I failed. I shall be up again in some 6 weeks or 2 months, & much hope then to see you.—4 If at any time you write again, please tell me whether I may call early & how early—
With very sincere thanks | Yours truly | C. Darwin
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.
