NATURAL SCIENCE. 



A Students' Manual of a Laboratory Course in 



Physical Measurements. 



By WALLACE CLEMENT SABINE, A.M., Instructor in Harvard Univer- 

 sity. 8vo. Cloth, ix+126 pages. Mailing price, $1.35; for intro- 

 duction, $1.25. 



manual, which is intended for use in supplementing col- 

 lege courses in physics, contains an outline of seventy experi- 

 ments in mechanics, sound, heat, light, magnetism and electricity, 

 arranged with special regard to a systematic and progressive de- 

 velopment of the subject. The description of each experiment is 

 accompanied by a brief statement of the physical principles and 

 definitions involved, and a proof of necessary formulae. 



Le Koy C. Cooley, Professor of 

 Physics, Vassar College : I have ex- 

 amined it and am ready to com- 

 mend it. 



Fernando Sanford, Professor of 

 Physics, Leland Stanford Junior 

 University: I like the book very 



much. It is better adapted to the 

 kind of work which I am trying to 

 do than any other book I have seen. 

 J. F. Woodhull, Professor of Sci- 

 ence, Teachers' College, New York: 

 I find Sabiue's Laboratory Manual 

 a thoroughly good thing. 



High School Laboratory Manual of Physics. 



By DUDLEY G. HAYS, CHARLES D. LOWRY, and AUSTIN C. RISHEL, 

 Teachers of Physics in the Chicago High Schools. 8vo. Cloth. 

 iv + 154 pages. Mailing price, 00 cents; for introduction, 50 cents. 



manual has been written: First, to present a logically 

 arranged course of experimental work covering the ground 

 of Elementary Physics. Second, to provide sufficient laboratory 

 work to meet college entrance requirements. It contains equiva- 

 lents of most of the exercises in the Harvard Pamphlet. 



The experiments are largely quantitative, but qualitative work 

 is introduced. Apparatus has been chosen that may in most 

 cases be duplicated at small cost. Special care has been taken to 

 make details of work clear, and to instruct the pupil in the 

 methods of making generalizations from his results. Alternate 

 pages are blank for convenience in taking notes. 



W. S. Jackman, Teacher of Science, 

 Cook Co. Normal School, Englewood, 

 III. : It is a most excellent manual 



and I believe it meets the needs of 

 high schools on this subject better 

 than any other book I have seen.
