BY J. S. SKINN ER. Assistant Post-Master-General, and Editor of the Turf Register.

This edition of Youatt's well-known and standard work on the Management, Diseases, and Treatment of the Horse, has already obtained such a wide circulation throughout the country, that the Publishers need say nothing to attract to it the attention and confidence of all who keep Horses or are interested in their improvement.

"In introducing this very neat edition of Youatt's well-known book, on ' The Horse,' to our readers, it is not necessary, even if we had time, to say anything to convince them of its worth; it has been highly spoken of, by those most capable of appreciating its merits, and its appearance nnder the patronage of the 'society for the Diffusion of Useful Knowledge,' with Lord Brougham at its head, affords a full guaranty for its high character. The book is a very valuable one, and we endorse the recommendation of the editor, that every man who owns the ' hair of a horse,' should have it at his elbow, to be consulted like a family physician,' for mitigating the disorders, and prolonging the life of the most interesting and useful of all domestic animals.' " - Fanner's Cabinet.

"This celebrated work has been completely revised, and much of it almost entirely re-written by its able author, who, from being a practical veterinary surgeon, and withal a great lover and excellent judge of the animal, is particularly well qualified to write the history of the noblest of quadrupeds. Messrs. Lea and Blanchard of Philadelphia have republished the above work, omitting a few of the first pages, and have supplied their place with matter quite as valuable, and perhaps more interesting to the reader in this country; it being nearly 100 pages of a general history of the horse, a dissertation on the American trotting horse, how trained and jockeyed, an account of his remarkable performances, and an essay on the Ass and Mule, by J. S. Skinner, Esq., Assistant Post-.naster-Geneial, and late editor of the Turf Register and American Farmer. Mr. Skinner is one of our most pleasing writers, and has been familiar with the subject of the horse from childhood, and we need not add that he has acquitted himself well of the task, He also takes up the important subject, to the American breeder, of the Ass. and the Mule. This he treats at length and con amine. The Philadelphia edition of the Horse is a handsome octavo, with numeroous wood-cuts " - American Agriculturist.
