A PRACTICAL GERMAN GRAMMAR; or a New and Easy Method of acquiring a thorough knowledge of the German Language; for the use of Schools and Private Students. By John Rowbotham, Master of the Classical, &c. Academy, Walworth. 12mo. price 6s. 6d. boards; or 7s. bound.

"Mr. Rowbotham has produced the clearest German and English Grammar that we have seen. The study of German has hitherto been obstructed in England by the circumstance that the Grammars of that Language have been the forbidding productions of Germans, and hence they have been German and English, instead of being English and German. By means of Mr. Rowbotham's luminous grammar, in which he exhibits a corresponding familiarity with both languages, the study of German is likely to be considerably promoted."—Monthly Mag. June, 1824.
