Vlll CONTENTS. 



CHAPTER VL 



Explosion by influence Dynamite detonates neighbouring cartridges in 

 indefinite numbers Explosion transmitted by water Theory founded 

 on existence of the " explosive " wave Abel's theory of " synchronous 

 vibrations" Explanation of these experiments according to the two 

 waves, one mechanical, the other chemical Chemical stability of 

 matter in sonorous vibration .. .. .. .. Page 75-87 



CHAPTER VII. 



Explosive wave Analogies and differences between this and the sound wave 

 Comparative rapidity of the two kinds of wave Experimental arrange- 

 ments Tubes of lead, glass, caoutchouc Tables showing theoretical 

 and found velocities of the wave in various gaseous mixtures Influence 

 of initial inflammation Propagation of explosive wave quite distinct from 

 ordinary combustion .. .. .. .. .. .. 88-113
