Mr. Warren’s works on Law are almost as entertaining as his novels. The present book is full of matter important to the young lawyer, and interesting to the general reader. All who are accustomed to have dealings with the profession, can obtain from this little volume many useful and some lucrative hints. The two points on which Mr. Warren expends his sense and his eloquence are knavery and incapacity, as those qualities exist among lawyers. As many lives and more fortunes depend on the existence of the opposite qualities in the profession, this volume will be equally valuable if it succeed either in expelling rogues and dunces from the law, or in enabling clients to detect them. * * * * * _Aurifodina; or Adventures in the Gold Region. By Cantell A. Bigby. New York: Baker & Scribner. 1 vol. 16mo._ The author of this little volume has availed himself of the interest excited by the late disclosures in California, to construct a story of marvelous adventures in that region. In regard to probability the work is half way between Gulliver’s Travels and the Arabian Nights. As every thing wonderful relating to California is greedily devoured, the disclosures of this work will undoubtedly receive their due attention. They are nearly as much entitled to belief as many of the newspaper accounts. * * * * * _A New Spanish Reader: Consisting of Passages from the Most Approved Authors, in Prose and Verse. By Mariana Velasquez de la Cadena. New York: D. Appleton & Co. 1 vol. 12mo._ The editor of this volume is Professor of the Spanish Language and Literature in Columbia College. He has so arranged his matter as to remove all possible obstacles in the way of the learner, and to conduct him, step by step, into the heart of the noble language of Castile. The selections are admirably made. The volume is not only well adapted for schools and colleges, but for the private student, and we trust it will induce many to study a language which will give them a key to the versatile and fertile genius of Lope de Vega, the mystical beauty of Calderon, and the profound and genial humor of Cervantes. * * * * * _Essay on the Union of Church and State. By Baptist W. Noel, M. A. New York: Harper & Brothers. 1 vol. 12mo._ This work has produced a considerable sensation in England, being a well-written protest against the Church Establishment, supported by a long array of facts and arguments. The author was for twenty-two years an Episcopal clergyman, and was at last forced by his reason and conscience into his present position. Mr. Noel does not attack the doctrines of the Church, but its union with the State, and he attempts to prove that this union is condemned by the letter and spirit of the Bible, is unjust, inexpedient, and productive of a host of evils, from which free churches are exempt.
