chase it with a view to carry it to Europe, but the price put upon it was above my means.

My excellent friend Richard Harlak, M. D. of that city, speaking of this bird in a letter dated "Philadelphia, August 19, 1830," says, "That fine specimen of Washington Eagle, which you noticed in Braxo's museum, is at present in my possession. I have deposited it in the Academy, where it will most likely remain." I saw the specimen alluded to, which, in as far as I could observe, agreed in size and markings exactly with my drawing, to which, however, I could not at the time refer, as it was, with the whole of my collection, deposited in the British Museum, under the care of my ever kind and esteemed friend J.

The glands containing the oil used for the purpose of anointing the surface of the plumage were, in the specimen represented in the plate, extremely large. Their contents had the appearance of hog's lard, which had been melted and become rancid. This bird makes more copious use of that substance than the White-headed Eagle, or any of the tribe to which it belongs, excepting the Fish-hawk, the whole plumage looking, upon close examination, as if it had received a general coating of a thin clear dilution of gum-arabic, and presenting less of the downy gloss exhibited in the upper part of the White-headed Eagle's plumage. The male bird weighs 14½ lb. avoirdupois, and measures 3 feet 7 inches in length, and 10 feet 2 inches in extent.
