body, a force is expended exactly equivalent 

 to the work done." 



2. That in long parallel tubes of the same 

 diameter, the number of opportunities of 

 action in the same time is nearly the same at 

 all velocities of the current gas. 



3. That in long parallel tubes of different 

 diameters, the number of opportunities of 

 action of each molecule of copper salt is the 

 same when the velocities of the current of 

 gas are in inverse proportion to the squares of 

 the tubes' diameters. 



4. That in porous masses the opportunities 

 of action increase with increased velocities of 

 the current gas in nearly direct proportions. 



5. That, other conditions remaining the 

 same, the percentage of hydrochloric acid 

 decomposed in any given time varies with 

 the square root of the proportionate volume 

 of oxygen to hydrochloric acid, conversely of 

 course, the percentage of oxygen used varies 

 with the square root of the proportionate 

 volume of hydrochloric acid to oxygen. 



6. That the cupric chloride formed bears 

 no definite proportion to the quantity of 

 chlorine produced. 



7. That as the sphere of action includes 

 molecules not in contact with the copper salt,
