SPECIFIC GRAVITY AND DISPLACEMENT OF SOME SALINE SOLUTIONS. 133 



of the table, when chlorine is replaced by iodine, the numbers expressing the differences 

 of the increments of displacement for the same value of m are the sum of the differences 

 for Br— CI, I— Br. 



Turning now to Table II., we have the increase in the increment of displacement 

 produced when the metal in combination with the same acid is varied. Here again it 

 will be found that the numbers on the same line in each section are, i7iter se, of the 

 same order of magnitude till m= 1/32, after which they vary more or less irregularly. 



Table L, giving the corresponding Differences between the Values of the Increments of 



Displacement, i\ caused by the Dissolution of m gram-molecule of MBr and 



MCI; MI and MBr; MI and MCI (where M = K, Rb, or Cs) in 1000 grams of 



Waterat 19-5°C.
