MR J. Y. BUCHANAN ON THE 



§ 57. Tables III. and IV. deal with the salts of the ennead MRO3, and correspond 

 in arrangement with Tables I. and II. respectively; and what has been said of the 

 two previous tables holds good, in general, with these two tables, but the agreement 

 of the values is not so close, nor is the number of values tabulated so great. In 

 Table III. the differences of the increments are nearly all negative quantities ; in 

 Table IV. they are all positive. 



Table V. gives the differences of v between the oxyhalides and the halides of the 

 same metal for the two enneads, MRO3 and MR, and here also the same characteristic 

 agreement is noticed between the numbers on the same line in each section of the table. 

 Having thus briefly explained the contents of the tables and the chief characteristics of 

 the numbers in them, we will proceed to more fully discuss the effects produced on the 

 displacement of 1000 grams of water at 19 '5^ C, when the constituents of the salts 

 dissolved in it are changed ; and in order to compare the results of the halides with those 

 of the oxyhalides, we shall confine our attention to the numbers for m^ 1/16 and less.

 ments of Displacement, v, caused by the Dissolution of m gram-molecule of 

 MBrOg and MCIO3 ; MIO3 and MBrOg ; MIO3 and MCIO3 (where M = K, Rb, 

 or Cs) in 1000 grams of Water at 19-5° C. .
