From Seth Sutton 8 August 1867
Zoological Gardens | Regents Park
Aug. 8th. 67
In accordance with your request, I beg to say that I have made the following observations respecting the animals you refered too.1 the Chimpanzee and Orang, when they Cough or sneeze they then shut their eys. When screaming violently they do not shut their eys, and if suddenly alarmed they then erect their hair. At extraordinary noise, such as Thunder—hamering &c, &c, they become excited, and if teased or anoyed the same. When they listen or are astonished their mouths are Closed. 2
When excited the hair stands erect from the back part of the neck to the loines, the other part (the rump) remaining quite smooth3
Nither the Chimpanzee nor the orang use their lips as an organ of touch when examining any strange object—
In Conclusion I beg to say if theres anything else you require notice off I shall be pleased to attend 〈to it〉—
I am Sir your obdt. Servant.—
C. Darwin Esqr.
Reports observations, as requested by CD, on expression in chimpanzees and orangs at Zoological Garden, London [see Expression, p. 95].
