The general color of the upper part of this bird is copper-brown, dark and shining. The throat and breast are a cinnamon color, the wings brown, with sprinklings of black, and the lesser wing-coverts rusty iron-gray. This description should, however, be received with some caution, in consequence of its being taken from but a few specimens, which varied considerably among themselves. The head is more convex than that of the Bald Eagle, the bill more hooked, and the iris of the eye is hazel, inclining to chestnut. Underneath the foot is notched like a rasp, to enable the bird to hold its prey. The majestic appearance of this Eagle, his great strength and superior size, justly entitle him to a rank among the noblest birds of our continent. * * * * * REVIEW OF NEW BOOKS. _The History of the United States of America, from the Discovery of the Continent to the Organization of the Government under the Federal Constitution. By Richard Hildreth. In three volumes. New York: Harper & Brothers, vol. 1._ The object of Mr. Hildreth’s ambition in this work is to present an impartial view of the persons and events of American history in their natural order and relations, and in his preface he plumes himself on having accomplished his purpose, at the same time not very modestly indicating his belief that no other American historian has approached it. As far as regards his claim to accuracy and impartiality we doubt not it will be readily admitted, at least in the sense in which he appears to understand the terms. The history is a useful compendium of facts undertaken by a man who does not seem to have sufficient sympathy with his subject to be capable even of partisanship. Everything indicates that the work was manufactured in a spirit of dogged, straight-forward, joyless labor. The author has in his other productions given evidence of passions sufficiently quick and hot, and a talent for hating almost unmatched for brilliancy and intensity, and our surprise was correspondingly great to find him in the present work altogether destitute of enthusiasm, and writing sentence after sentence with no inspiration even from his blood.
