A COMPENDIOUS MANUAL OF QUALITATIVE CHEMI 

 CAL ANALYSIS. By CHARLES W. ELIOT and FRANK H. STORER. 

 Revised with the Cooperation of the Authors, by WILLIAM RIP- 

 LEY NICHOLS, Professor of Chemistry in the Massachusetts Insti 

 tute of Technology. 



&quot; This Manual has great merits as a practical introduction to the science 

 and the art of which it treats. It contains enough of the theory and practice 

 of qualitative analysis, &quot; in the wet way, to bring out all the reasoning in 

 volved in the science, and to present clearly to the student the most approved 

 methods of the art. It is specially adapted for exercises and experiments in 

 the laboratory; and yet its classifications and manner of treatment are so 

 systematic and logical throughout, as to adapt it in a high degree to that 

 higher class of students generally who desire an accurate knowledge of the 

 practical methods of arriving at scientific facts.&quot; Lutheran Observer. 



&quot; We wish every academical class in the land could have the benefit of the 

 fifty exercises of two hours each necessary to master this book. Chemistry 

 would cease to be a mere matter of memory, and become a pleasant experi 

 mental and intellectual recreation. We heartily commend this little volume 

 to the notice of those teachers who believe in using the sciences as means of 

 mental discipline.&quot; College Courant.

WEIGHTS AND MEASURES. An Account of the Decimal 

 System, with Tables of Conversion for Commercial and Scientific 

 Uses. By B. F. CRAIG, M. D. 



&quot; The most lucid, accurate, and useful of all the hand-books on this subject 

 that we have yet seen. It gives forty-seven tables of comparison between the 

 English and French denominations of length, area, capacity, weight, and the 

 Centigrade and Fahrenheit thermometers, with clear instructions how to use 

 them ; and to this practical portion, which helps to make the transition as 

 easy as possible, is prefixed a scientific explanation of the errors in the metric 

 system, and how they may be corrected iu tho laboratory.&quot; Nation. _;
