Column 1 contains the temperatures ; column 3 the ten- 

 sions, as deduced from Dalton's experiments ; and column 

 4 the same as given by Kamtz. 



Table II. 



When the corresponding numbers in the three columns 

 are compared, it will be at once observed, that the values of 

 /, investigated by the method just explained, are somewhat 

 less than those extracted from the table I have been hitherto 

 in the habit of using; but that they are considerably greater 

 than the values of Kamtz, the differences being generally 

 better than twice as great in the latter instance as in the 

 former. This will be more manifest by taking a mean of the 

 different results in column 2, and comparing it with the force
