GREENE'S ANALYSIS. A TREATISE ON THE STRUCTURE OF THE ENGLISH LANGUAGE; or the Analysis and Classification of Sentences and their Component Parts; with Illustrations and Exercises, adapted to the Use of Schools. _By Samuel S. Greene, A.M._, Principal of the Phillips' Grammar School, Boston. Philadelphia, 1848. Price, 45 cts. This work has already reached the sixth edition in the space of four months. _From the Christian Review._ We like the book much--it is just what is wanted in our Grammar Schools; and if accompanied by an abridgement, for the younger pupils, which the author proposes in his preface to prepare, will leave but little to be desired for the purposes of ordinary instruction in Grammar, in our schools. The plan is simple, and is developed with great consistency and logical ability. _Copy of a Letter from Mr. Elbridge Smith, Principal of the Cambridge High School._ Dear Sir--I have examined with great pleasure the Grammar which you did me the honour to send me. I have no hesitation in saying that I consider it _the best English Grammar in existence_. This, I am aware, some will regard as extravagant praise. I am not, however, alone in my opinion. Indeed, I know of no one, who has given attention to the subject, who is not of the same opinion. Greene's First Lessons in English Grammar, Based upon the Construction and Analysis of Sentences: designed as an Introduction to the Analysis. A few testimonials are subjoined:-- _City of Boston--In School Committee._ _Ordered_, That Greene's First Lessons in Grammar take the place of Allen H. Weld's Abridgment, subject to the conditions prescribed by the regulations. Attest: S. F. M'CLEARY, _Secretary_. _From M. F. Cowderey, late Chairman of the Executive Committee of the Ohio State Teachers' Association, and President of the Northwestern Educational Society._ I, and some of my friends, Teachers in this State, have given the work our examination, and we think so highly of it that we shall use it ourselves, and urge its general introduction into the Schools of Ohio. These books are introduced in the Public Schools of Boston, Cincinnati, St. Louis, Vicksburg, and into many towns in New York, Ohio, and other States. FROST'S HISTORY OF THE UNITED STATES.
