LABORATORY MANUAL OF PHYSICS. 



Laboratory Exercises in Elementary 

 Physics. 



A Manual for Students in Academies and 

 Higii Schools. By Franklin H. Ayres, In- 

 structor in Physics in Central High School, 

 Kansas City, Mo. i2mo. Cloth, 60 cents. 



SIX PARTICULARS. 



1. This Manual is strictly in line with the best university 



practise. 



2. It keeps within the limits of legitimate laboratory work 



in elementary physics. 



3. Its exercises demand work and thought worthy of the 



best student, but within the range of the average. 



4. It is perfectly clear with respect to {a) The general 



object of the exercises ; {b) How the work is to be 

 done ; and {c) The road the student must travel to 

 arrive at the conclusions involved. 



5. Its course in measurements is founded on the cardinal 



principle that no physical law with a quantitative 

 aspect can be understood until the beginner can 

 express in mathematical form both the law itself and 

 the process by which he verified it. 



6. It presents laboratory physics in the spirit and by the 



practise of pure induction, yet carefully avoids the 

 absurdity of supposing that young students are capa- 

 ble of original investigation.
