In 1839 Audubon commenced in this country the republication of the "Birds of America," in seven large octavo volumes, which were issued during the succeeding five years. Before the expiration of this period, however, he commenced the preparation of the "Quadrupeds of America," of which he had materials for five large volumes: in the literary department of which he was assisted by Dr. Bachman, of Charleston. This has recently been concluded, and forms a monument to his memory hardly less imposing than his earlier work. In the meanwhile, though more than sixty winters had passed over his head, he projected an expedition to the Rocky Mountains, with all the adventurous spirit of his youth. But he perhaps over-rated his physical capabilities; at least the expedition was not made. The concluding years of his life were passed on the beautiful estate of Minniesland, upon the Hudson, some ten miles from New York. For several years his health had been giving way, until the time when he passed from earth to the still land of the immortals. His was a happy life. He had found his vocation, and pursued it for long years, earnestly, faithfully, and triumphantly. The forms of beauty which won his early love, and drew him into the broad forests, he brought back to cheer us who can not follow his footsteps. He has linked himself with the undying loveliness of Nature; and, therefore, his works are a possession to all men forevermore. JOSEPH BEM, the famous Polish General in the late Hungarian war, died at Aleppo in the early part of December. It is somewhat singular that during the whole course of hostilities he declared his conviction that he should survive until the year 1850. Bem was born in 1795 at Tarnow in Gallicia. Having completed his education at the Military School in Warsaw, he entered the army, and served as lieutenant of artillery in the divisions of Davoust and Macdonald. On the conclusion of peace, he remained with the Polish army, who were now in the Russian service, where he attained the rank of captain and adjutant, and was finally appointed teacher in the Artillery School at Warsaw. Dissatisfied with his position, he applied for a discharge, which was granted; but for some unexplained cause he was summoned before a court-martial, and sentenced to an imprisonment of two months. From 1825 to the outbreak of the Polish insurrection in 1830, he resided at Lemberg, where he busied himself with mechanical and mathematical studies. When the rising of the Poles took place, he hastened to Warsaw, was appointed major, and obtained the command of a regiment of flying artillery. For his distinguished services at the battles of Igania and Ostrolenka he was raised successively to the rank of lieutenant-colonel and colonel, and received the command of the Polish artillery. At Ostrolenka he was wounded, but as he lay upon the ground, he directed the movements of his guns. When the cause of Poland was lost, he headed the first emigration
