New Planet.—The Tempo, of Naples, publishes a letter from M. Leopold Del Re, Director of the Observatory at Naples, announcing that the celebrated astronomer, Don Annibale de Gasparin, late discoverer of the Igea Borbonica, has discovered a new telescope planet, being the ninth between Mars and Jupiter. It is a star of the ninth magnitude, and is at present in apposition with the sun.
In Surgery.—A correspondent of the Lowell Courier claims for the late Dr. Twitchell, of Keene, the honor of successfully tying the carotid artery several months before Sir Astley Cooper made the attempt. The latter has always had the credit of being the first to achieve this extremely difficult and dangerous process.
AUTHORS AND BOOKS.
The Rev. Thomas H. Smyth, D.D. of South Carolina, whose work upon the Unity of the Human Races, suggested by the recent declarations of infidelity, by Professor Agassiz of Harvard College and others, has been published by Putnam, and received with a hearty applause by Christians and scholars, is not, as is commonly supposed, an American author, though he has long resided in this country. He was born in Belfast, in the North of Ireland, and educated at the Royal College in that city, pursuing afterward his theological studies in London, and at Princeton in New Jersey. He has been eighteen years minister of the Presbyterian church in Charleston, where he was married, and where he will probably always reside, while in this country; but his liberal fortune and inquiring spirit tempt him to frequent travel, and he is now absent upon a tour which will probably be extended to Nineveh and all the most interesting scenes connected with the history of religion in the eastern world. Dr. Smyth possesses one of the largest and most valuable private libraries in the United States, and has therefore been able to compose his learned works in theology, history, &c. under advantages but seldom enjoyed by our authors. His chief productions are, Apostolical Succession, 1842; Presbytery and not Prelacy the Scriptural and Primitive Polity of the Church, 1843; Ecclesiastical Republicanism; Ecclesiastical Catechism; Claims of the Free Church of Scotland; Life and Character of Thomas Chalmers, with Personal Recollections; Nature and Functions of Ruling Elders; Nature and Functions of Deacons; The Rite of Confirmation examined; Bereaved Parents Consoled; Union to Christ and His Church; The True Origin and Source of the Mecklenburg Declaration of Independence, with a Continuation on Presbyterianism, the National Declaration, and the Revolution; Denominational Education; Pastoral Memento; Life and Character of Calvin; The Westminster Assembly; and the Unity of the Human Races proved to be the Doctrine of Scripture, Reason, and Science. Dr. Smyth has also written largely in the Biblical Repertory, the Southern Presbyterian Review, and other Periodicals.
The Veteran Italian General Pepe, known in the book-world heretofore by his Personal Memoirs, has just published a Narrative of Scenes and Events in Italy, from 1847 to 1849. It comprises the most interesting particulars respecting the Revolutions in Naples, Sicily, and Rome; the Military Operations of Charles Albert; and the Siege of Venice, of which city General Pepe held the command.
