Coefficient of Volume Elasticity of Metals. 



hut the temperature effect can be readily eliminated from the 



observations. 



In the experiments, the results of which are recorded below, the 

 maximum fluid pressure in the tube was 400 Ibs. per square inch. 

 The longitudinal extension was measured at 100, 200, 300, and 

 400 Ibs. pressure, and the extensions when corrected for temperature 

 and plotted in terms of pressure lay on a straight line within the 

 limits of error.
