JOHNSOK 



The Chemistry of Common Life. 



Illustrated with numerous Wood Engravings. 

 By JAMES F. JOHNSON, M. A., F. R. S., F. G. S., ETC., ETC., 



Author of "Lectures on Agricultural Chemistry and Geology," "A Catechism of Agricultural 

 Chemistry and Geology,' 1 etc, 



2 vols., 12mo. Cloth, $3.00. 



It has been the object of the author in this work to exhibit the 

 present condition of chemical knowledge, and of matured scientific 

 opinion, upon the subjects to which it is devoted. The reader will not 

 be surprised, therefore, should he find in it some things which differ 

 from what is to be found in other popular works already in his hands or 

 on the shelves of his library.

 Medical Recollections of the Army of 



the Potomac. 



By JONATHAN LETTERMAN, M. D., 



Late Surgeon U. S. A^, and Medical Director of the Army of the Potomac. 



1 vol., 8vo. 194 pp. Cloth, $1.00. 



" This account of the medical department of the Army of the Poto- 

 mac has been prepared, amid pressing engagements, in the hope that 

 the labors of the medical officers of that army may be known to an in- 

 telligent people, with whom to know is to appreciate ; and as an affec 

 tionate tribute to many, long my zealous and efficient colleagues, who, 

 in days of trial and danger, which have passed, let us hope never to re- 

 turn, evinced their devotion to their country and to the cause of hu- 

 manity, without hope of promotion or expectation of reward." Preface. 



" We venture to assert that but few who open this volume of medical annals, 

 pregnant as they are with instruction, will care to do otherwise than finish them 

 at a sitting." Medical Record. 



" A graceful and affectionate tribute." N". T. Medical Journal 



LEWES. 

 The Physiology of Common Life. 



By GEORGE HENRY LEWES, 



Author of "Seaside Studies," "Life of Goethe," etc. 



2 vols., 12mo. Cloth, $3.00. 



The object of this work differs from that of all others on popular 

 science in its attempt to meet the wants of the student, while meeting 

 those of the general reader, who is supposed to be wholly unacquainted 

 with anatomy and physiology.
