such a sugar solution will be highly changed by adding aiiy 

 of the salts mentioned, The inner friction of a 2-/7 sugar 

 solution is about 26, n. By adding so much KCl to this 

 solution, that it becomes 2-/7 even with regard to this salt, 

 the viscosity is decreased to 23,53. If the solution be made 

 2-n with regard to LiCl, ij is increased to 42,6, and so forth. 

 In the former case we find a diminution of the viscosity 

 of 10 percent, in the latter case, again, an increase excee- 

 ding 50 per cent. These percentages of course highly depend 

 both on the electrolyte and the non-electrolyte concentration, 

 and they decrease when the quantities of the substances 

 decrease. (See the tables pag. 76 — 81). ^) 



From these tables we can, however, obtain a sort of 

 qualitative averages for instance for the influence of 2-/7 

 LiCl upon the inner friction of the sugar solutions (2-/7 . . . 

 0,1-/7). Similarly for the influence of 2-/7 KCl, and so forth, 

 and corresponding numbers for the glycerine solutions. Then 

 we find the following mean values: 



2-/7 KCl dimin. the viscosity of glycerine solutions with 4 % 

 1-/7 » » » » » » 2 — 3% 



0,25-/7 » » » » » » 0,5 — 1 % 



These figures, of course, only form rough averages. 



From the table on pag. 4 — 7 we can calculate similar mean 

 values for the influence of these salts upon the diffusion 

 of the cane sugar and the glycerine, and we find that:
