mobility of the molecules. These circumstances have been 

 discussed before ^). 



From the above investigation the following conclusions 

 may be drawn: 



If the water in which a non-electrolyte diffuses contains 

 an electrolyte, the diffusion coefficient of the non-electrolyte 

 is considerably changed, particularly if the salt concentration 

 is great. 



The diffusibility can on the one hand be increased if the 

 water contains KCl, on the other hand it can be reduced 

 if the electrolyte is LiCl. 



These effects in the first place depend on the influence 

 exerted by the said salts upon the viscosity of the solutions.
