Farmer, Brace 4- Go's Publications. 7 



The Publishers feel justified in claiming that the Students' Series is decidedly the 

 best for teaching reading, and spelling that has yet appeared. The plan of teaching 

 includes, in the first steps, an ingenious and original mode of repetition which is 

 very pleasing and encouraging to the pupil. The first books of the series are very 

 instructive, and the later portions consist of fine selections, which are not hack- 

 neyed. Prof. Page, late Principal of the New York State Normal School, said of this 

 system: " It is the best I ever saw for teaching the first principles of Reading." 

 Such testimony is of the highest value, and none need be afraid to use the books on 

 such a recommendation. 



The numerous notices from all parts of the country where these books have been 

 used, cannot be introduced here. They have just gone into the schools of Seneca 

 County, N. Y., without solicitation ; and the same is true of many important 

 schools where they have been examined. 



From C. B. CRUMB, N. Y. 



The Students' Series is, in my opinion, the best in use. I believe a class of young 

 students will learn twice as much, with the same labor, as they would from any other 

 system. The books of this Series excel in the purity and attraction of their style 

 I have introduced them.

QUESTIONS AND ILLUSTRATIONS TO THE PHILOSOPHY 30 



All the above works are fully illustrated by elegant cuts. 



The Philosophy has been republished in Scotland, and translated for the use p 

 schools in Prussia. The many valuable additions to the work by its transatlantic 

 editors, Prof. Lees, of Edinburgh, and Prof. Iloblyn, of Oxford, have been embraced 

 by the author in his last revision. The Chemistry has been entirely revised, and 

 contains all the late discoveries, together with methods of analyzing minerals and 

 metals. Portions of the series are in course of publication in London. Such testi- 

 mony, in addition to the general good testimony of teachers In this country, is suffi- 

 cient to warrant us in saying that no works on similar subjects can equal them, or 

 have ever been so extensively used. Continual applications arc made to the publish- 

 ers to replace the Philosophy in schools where, for a time, it has given way to other 

 booke. The style of Dr. Comstock is so clear, and his arrangement is so excellent, 

 that no writer can be found to excel him for school purposes, and he takes constant 

 pains to include new discoveries, and to consult eminently scientific men.
