 CAL ANALYSIS. By Chabies W. Eliot and Frank H. Stokek. 

 Hevised with, the Cooperation of the Authors, by "Wiixiam Eip- 

 lET Nichols, Professor of Chemistry in the Massachusetts Insti- 

 tute of Technology. 



" This Manual haj9 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, " 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 ars 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." — Lviheran Obterver, 



" 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." — College Courant.

 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 metrio 

 system, and how they may be coneoted in the laboratory." — NaiHon.
