afford the means of deciding between our two British Eagles
at any age ; and the three anterior toes of both species are
therefore figured as a vignette to the second British Eagle,
to show the distinction. The foot on the left hand is that
of the Golden Eagle, in which each toe is covered with
small reticulations as far as the last phalanx, then with the
three broad scales already referred to. In the foot of the
White-tailed Eagle, represented by the figure on the right
hand, the reticulations are confined to the tarsus, the whole
length of each toe being covered with broad scales.
The figure of the Golden Eagle at the head of this article
was taken from a fine specimen at the Garden of the Zoological
Society, where it has lived for eight years.
The figures below represent the crystalline lens and the
bony ring of the eye of the Golden Eagle, referred to at
page 11.
