t.f.y Nichols, Professor of Chemistry in the Massachusetts Insti 
tute of Technology. 
“ 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, “ in the wet vay,’* to bring out all the reasoning in- 
volved in the Science, and to present clearly to the student the most approved 
mefhods 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 dass of students generally who desire an accurate knowledge of the 
practical methods of arrivmg at scientific facts.”—Lutheran Observer. 
“ We wish every academical dass 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 heartlly commend this little volume 
to the notice of those teachers who believe in using the Sciences as means of 
mental disdpline.”—College Courant.

“ The most lucid, aecurate, 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 nse 
them; and to this praetical portion, which helps to make the transition as 
easy as possible, is prefixed a scientific explanation of the errors in the metric 
jyatem, and how they may be correctcd in the laboratory.”—Nation.
