§ 54. Solutions of the Salts of the Ennead MR. — The notes deal principally with 

 the character of the change in the value of d^ — v with changes of the value of min 

 the different solutions. 



Table I. : — KCl. — This salt is the subject of the specimen table, § 50, and it 

 has been commented on in connection with that table. 



Table II. : — RbCl. — In all three sub-tables the change of sign occurs between 

 m= 1/128 and w= 1/256. There is a steady decrease in the positive values from 

 m=l/4 to m= 1/128 in all three cases, excepting sub-table a at m=l/64, when an 

 increase over the previous value occurs. 



The solutions of this salt show a regular decrease from high positive values of 

 dA — V to small negative values at low concentrations. 



Table III. :— CsCl. — The series of values of d^ — v in the three sub-tables shows 

 a very regular decrease in magnitude from m = 1/4 to m = 1/256 ; change of sign occurs 

 between m= 1/256 and 1/512 with a small negative value. 



Table IV. : — KBr. — There is a rapid decrease in the value of dA — v from m— 1/4 

 to m=l/l6, and between 7n=l/l6 and m=l/32 there is change of sign to a small 

 negative value, which persists right on to m= 1/512, and which is the characteristic 

 feature of the three sub-tables.
