MATERIALS NEEDED FOR THE EXERCISES IN 

 THE LABORATORY 



Below is given a list of materials and apparatus needed by one 

 pupil, to perform all the experiments and exercises in the MANUAL. 



Nearly all of these articles are possessed by a school which has 

 courses in physics or chemistry. By cooperation and a little planning 

 to avoid conflict as to time, balances, thermometers, compasses, and 

 the like might be used by classes in different branches of science. It 

 is far better, however, unless the work is all done in the same labora- 

 tory, that each department should have and should care for its own 

 apparatus. 



Many of the pieces can be used year after year. Some can be 

 obtained from local dealers or from the homes of pupils. 



It is not necessary that the exercises should be done at the particular 

 place in the course to which they are assigned. If it is impossible to 

 arrange for that, it is better that the exercise should follow rather 

 than precede the study of a subject. 



Drawing compass. 



6-inch ruler divided into centimeters on one edge, inches 

 on the other.
