Darwin, Charles, 1809-1882

"The Expression of the Emotions in Man and Animals"


This also, I presume, is the reason that the eyes of a strangled
man appear as if they were starting from their sockets.

[14] I am greatly indebted to Mr. Bowman for having introduced
me to Prof. Donders, and for his aid in persuading this great
physiologist to undertake the investigation of the present subject.
I am likewise much indebted to Mr. Bowman for having given me,
with the utmost kindness, information on many points.
[15] This memoir first appeared in the `Nederlandsch Archief voor Genees
en Natuurkiinde,' Deel 5, 1870. It has been translated by Dr. W. D. Moore,
under the title of "On the Action of the Eyelids in determination of Blood
from expiratory effort," in `Archives of Medicine,' edited by Dr. L. S. Beale,
1870, vol. v. p. 20.
With respect to the protection of the eye during violent expiratory
efforts by the pressure of the eyelids, Professor Donders concludes from
his various observations that this action certainly limits or entirely
removes the dilatation of the vessels.[16] At such times, he adds,
we not unfrequently see the hand involuntarily laid upon the eyelids,
as if the better to support and defend the eyeball.
