water hydrochloric acid gas evolved out of the ordinary pure con- 
centrated hydrochloric acid. 
Concentrations of Solutions were obtained in most cases by volu- 
metric method, and the results were mostly checked by the con- 
centrations obtained from the weights of the salts dissolved. 
The followine tables eive the values of the molecular conductivities
