Messrs. Lea & Blanchard: 



Gentlemen: — I have examined the copy of " White's Universal History," which you were so 

 obliging as to send me, and cheerfully and fully concur in the commendations of its value, as a 

 comprehensive and enlightened survey of the Ancient and Modern World which many of the most 

 competent judges have, as I perceive, already bestowed upon it. It appears to me to be admira- 

 bly adapted to the purposes of our public schools; and I unhesitatingly approve of its introduction 

 into those seminaries of elementary instruction. Very respectfully, your obedient servant, 



SAMUEL S. RANDALL, Deputy Superintendent Common Schools. 



This work is admirably calculated for District and other Libraries: an edition for that purpose 

 without questions has been prepared done up in strong cloth.

CHEMISTRY FOR STUDENTS. 



ELEMENTARY CHEMISTRY, THEORETICAL AND PRACTICAL. 



BY GEORGE FOWNES, Ph. D., 



Chemical Lecturer in the Middlesex Hospital Medical School, &c. &c. 



With Numerous Illustrations. Edited, with Additions, 



BY ROBERT BRIDGES, M. D., 

 Professor of General and Pharmaceutical Chemistry in the Philadelphia College of 

 Pharmacy, &c., &c. 

 In one large duodecimo volume, sheep or extra cloth. 

 This is among the cheapest volumes on Chemistry yet presented to the profession. The charac- 

 ter of the work is such as should recommend it to all colleges in want of a text-book as an intro- 

 duction to the larger and more advanced systems, such asGraham-s and others. The great advan- 

 tage which it possesses over all the other elementary works on the same subject now before the 

 public, is the perfect manner in which it is brought up to the day on every point, embracing all 

 the latest investigations and discoveries of importance, in a concise and simple manner, adapted to 

 the time and comprehension of students commencing the science. It forms a royal 12mo. volume 

 of 460 large pages, on small type, embellished with over one hundred and sixty wood engravings, 

 which will be found peculiarly instructive as to the practical operations of the laboratory, and the 

 new and improved methods of experimenting. 



It has already been adopted as a Text-book by Professor SiJliman of Yale College, and by other 

 Colleges in different parts of the country. The Publishers have also numerous commendations.

GEOLOGY AND MINERALOGY, with instructions for the qualitative analy- 

 sis of Minerals. By Joshua Trimmer, F. G. S. With two hundred and 

 twelve wood cuts, a handsome octavo volume, bound in embossed cloth. 



This is a systematic introduction to Mineralogy, and Geology, admirably calculated to instruct 

 the student in those sciences. The organic remains of the various formations are well illustrated 

 by numerous figures, which are drawn with great accuracy.
