Cooley's Physical Science Series. — These books upon Natural 

 Philosophy and Chemistry, for graded schools and academic classes, 

 are intended to fill the mind of the student with practical information, 

 and to discipline it in modes of thought and observation. The matter 

 has been judiciously selected and thoroughly systematized. Technical 

 words are fully and clearly defined, and to this is added an illustration 

 or the description of an easy experiment, for the purpose of bringing 

 the meaning of the words and purport of the text to the comprehen- 

 sion of the merest child. The plan of the work is so pleasing, and the 

 arrangement so plain and instructive, that an industrious child might 

 master the philosophy and the science without the aid of an instructor. 

 An intelligent teacher, however, could not fail with these books to im- 

 press the entire matter upon the minds of each and every one, if he or 

 she simply performed the experiments in the presence of the class. If 

 the author intended to make Physical Science easy, and to place the 

 knowledge of it within the reach of every child in the country, he has 

 most successfully accomplished his work. Scribner, Armstrong & Co.,

Elements of Natural Philosophy, by S. A. Norton. — This 

 work, by an experienced teacher of the science of Physics, is method- 

 ically arranged and thoroughly illustrated. The definitions are full, 

 clear, and precise. The student is first introduced to a full and com- 

 prehensive statement of the properties of matter ; this is followed by 

 the philosophy of the mechanics of solids and fluids, undulations, 

 acoustics, optics, effects, distribution and soui'ces of heat and elec- 

 tricity, etc. Nothing seems to have been omitted from any depart- 

 ment of the science that would tend to make the work available as a 

 text-book, nor has anything been included that is not in its proper 

 place. The copious illustrations and accurate statements lead the 

 pupil at once to correct ideas of the phenomena of nature, without the 

 constant aid of a teacher. All obstacles are removed from the road to 

 a knowledge of the subjects treated, and on every hand are provided 

 the most pleasant and instructive retreats for thought and observa- 

 tion. The work will be found in the unparalleled series of school 

 books published by Wilson, Hinkle & Co., Cincinnati, Ohio.
