It is therefore probable that the two which left the nest at the approach
of the party were the young birds.
I made my drawing of them the day after their death. It was one of the severest tasks which I ever performed, and was done under the most disagreeable circumstances. I sat up nearly the whole of the night, to sketch them in outline. The next day it rained for hours, and the water fell on mv paper and colours all the while from the rigging of the Ripley. The weight of the female was 3 pounds 2 ounces, that of the male 2 pounds ] 4 ounces avoirdupois. Their flesh was tough and bluish, and their whole structure was remarkable for the indications of strength which it exhibited. The intestines measured 4 feet 9 inches. The heart was extremely large, and very remarkable for its firmness. The liver also was large. The stomach, which was thin, contained remains of fish, fea- thers, and hair.
From the account which I received from my son and his companions, I would willingly suppose that no one had ever before disturbed their so- litude. They flew about and close to them, as if altogether unacquainted with the effects of a gun. The young appeared full grown, and, as if aware of the fate of their parents, alighted only on the highest and most inaccessible parts of the rocks around. Both the specimens procured were carefully skinned and preserved. One is in my possession; the other I gave to my worthy and generous friend John Bachman.
When I first saw this noble pair of Falcons, I thought, as I have above said, that they were new ; but since my return to Europe, I have seen several specimens, which, though not altogether similar in the tints of the plumage, agree in most other respects with them, in so far as I can judge from the comparison of skins shrunk or distended beyond measure, such as we too often see in museums. These specimens are said to be young birds of the famous Iceland Falcon, and I am disposed to think that my birds belong to the same species.
That this species, as well as many others, should mate and produce young, before obtaining its full plumage, is not a singular phenomenon. I am persuaded that many years elapse before it obtains its perfect plumage, from the remarks made by a gentleman not yet personally known to me, although acquainted with my son Victoe, Mr John Heppenstall, of Upper Thorpe, near Sheffield, who has kept one of these birds alive for more than three years. Of his letter to my son, which is dated "5th month 14th 1834,"" the following is an extract. " The bird thou saw when at my
