This work comes to us under the fairest auspices. The author, M. CHAILLY, is a distinguished Parisian lecturer on Obstetrics, a pupil of the eminent PAUL DUBOIS, of the University of Paris, and generally recognized as the exponent of the views of that celebrated _accoucheur_. By all who are familiar (and who of the medical world is not?) with the high reputation of DUBOIS for sound medical philosophy and unbounded practical knowledge, it has been long regretted that the just opinions he so eloquently promulgates in the lecture-room have never assumed the diffusible shape of a printed book. M. CHAILLY, in the work before us, supplies us with that which has been so much desired, and which Prof. DUBOIS himself, from some cause not easily appreciated, has so long withheld from the world. The Parisian board of public instruction has moreover stamped the work of M. CHAILLY with their approbation, and fixed it as the standard text-book of the French medical schools. This is a promise of excellence which a diligent perusal of the work will fully confirm. Professor BEDFORD, the American translator, who has performed his duty as might be expected from his high character and prominent position, as Professor of the flourishing medical school of the University of New-York, felt the want of a good text-book for the student, and a sound practical guide for the physician, and has exhibited a sound judgment in this selection to supply that want. The work of VELPEAU, hitherto unquestionably the most popular book with the medical profession, is diffuse and speculative. The present work is direct, concise, and complete. Dr. BEDFORD has enriched the original with copious notes, the result of his own extensive experience and observation. The publishers have performed their duty well, in presenting the work in a handsome library form; and it is only the very extensive business facilities of the MESSRS. HARPERS that could afford so full and well illustrated a _scientific_ book at so reasonable a price.
