From J. W. Clark 16 September 1875
18 High Street | Southampton
Sept 16. 1875.
Dear Sir,
As promised by my letter of yesterday I forward a few instances briefly described—respecting the dilation of the pupils of animal’s eyes when suffering from fear.1 The appearance is that of Gratiolet quoted in the “Expression of the Emotions”—as if “gazing into profound darkness”—but with associated actions & appearances it also conveys to my mind most distinctly the impression of fear or dread.2
Should I be able to get any more opinions or observations I shall make note of them & should you desire it shall be happy to forward them to you at any time.
Believe me I remain dear Sir, yours very truly, | J W Clark
P.S. Any further inquiries or suggestions you have to make respecting my experiments on the Drosera I shall esteem an honour.3
