The increasing demand for a thorough, comprehensible, and practical 

 text-book on the subject is met by Rowell's " Introduction to General 

 Science." the distinctive features of which are : 



1 . The book gives a broad, adequate view of the general field of 

 science. The elements of physics and chemistry receive particular em- 

 phasis, but biology, physiography, and several phases of applied science 

 are duly considered. 



2. Despite the necessity for treating various sciences, the book is re- 

 markable for its continuity of thought. The interrelation of scientific 

 facts is constantly and clearly pointed out. 



3. The treatment is clear-cut, brisk, and thorough, the material well 

 chosen and up to date, while the general workmanship of the book 

 renders it attractive and serviceable. 



4. There are over 90 laboratory exercises in the book, a number of 

 them entirely new, and all of them illustrative of the text. 



5. Reference reading is encouraged, and lists of carefully selected 

 standard reference books are suggested. Those teachers, however, who 

 do not care to take up detailed work of this sort may give a satisfactory 

 course by using in connection with the book United States Government 

 bulletins alone, to which definite reference is made in the lists of refer- 

 ence readings throughout the book. 



TEACHERS 



call the book "thorough," "practical," " comprehensive," " clear," " sat- 

 isfactory," " a great aid to the science teacher." 



Mr. N. P. Lawson of Taunton, Washington, writes: 



"I have examined Rowell's 'Introduction to General Science' quite 

 carefully. It wears. The more I use it the better I like it. _ There is 

 room left for the teacher. He doesn't have to crowd himself in. This 

 book can hardly fail to innoculate any one with the bulletin habit, in 

 which I am a firm believer. In its encouragement of wide reading and 

 first-hand acquaintance with books through the excellent references 

 given, this compact little volume is an education in itself. If I were 

 with your company I should wish to push this book. I believe in it."
