Introduction to General Science, by Percy E. Rowell. The 

 Macmillan Co. Page XXIX+302. 75 cents. 



This is intended as a text book for a first year course m 

 science, such as is frequently being introduced now in the first 

 year of the high school. There are something over a hundred 

 experiments outlined, ninety-two of whidi are supposed to be done 

 by the pupil, and these experiments cover a number of subjects, 

 including ordinary combustion, conduction, distillation, center 

 of gravity, the seasons, electroplating, color, atmospheric pres- 

 sure, the making of a lx)omerang, the dew-point, osmotic pre^- 

 sure, sedimentation, digestion of proteids, fatigue, etc. It is 

 very evident, therefore, that the range of the book is very wide, 

 and a glance at the page headings makes this even more apparent. 

 The directions for the experiments are brief, concise, and yet as 

 a rule sufficient so that a teacher, though not a specialist, could 

 readily perform them. In most cases no expensive apparatus 

 is needed, although the apparatus suggested is what one would 

 ordinarily find in a laboratory. The teacher, however, who has 

 had the ordinary High School work in science, would find the book 

 of considerable help in the adaptation of our scientific knowledge 

 to some of the simple science of the upper grades. For the 

 High School teacher who wants a first year course the book is 

 an exceedingly suggestive one. There is quite an extensive 

 bibliography to which detailed reference is made throughout 

 the text, and there is appended a list of needed apparatus and 

 materials. Until High School teachers shall come to some agree- 

 ment as to what should be included in the High School course, 

 the best that can be done is for each teacher to experiment with 

 the materials that in his own opinion are best fitted for the High 

 School work; this book is interesting as an expression of opinion 

 as to. the character and extent of the material that should be 

 included in the first year High School science course.
