The writer of this paper, Mr. Marcus Gunn, is an acknowledged expert as
an oculist. His opinion, therefore, on the subject of the salmon’s
visual apparatus is of no ordinary value and should be duly pondered.
Perhaps we ought to inform our readers that the eyes of the two salmon
which he examined with a view to this paper were extracted from two
large fresh run fish caught in autumn by the undersigned—one on the
Ythan and the other on the Dee. The eyes were extracted immediately
after capture and placed, in one case in chloral, in the other in
formalin. Mr. Gunn was thus enabled to make sections of both, with the
results embodied in his authoritative paper.
