Per la teoria della dissociazione elettrolitica in solvent! diversi dall'acqua. III. 

 Influenza del solvente sopra i numeri di trasporto. Gazz. chim. jj, I, 241. 



Apparatus: (i) see Loeb and Nernst ; capacity 30 c.c. ; 

 (ii) cylindrical glasses superposed on one branch of a U-tube, 

 the bottom of each being closed by fish bladder ; capacity 40- 

 70 c.c. ; (iii) an M-tube without diaphragms with outlets on the 

 three lower extremities ; capacity 100 c.c. ; two middle portions 

 with a change 2-20 percent as great as the end portions ; 25 °C. 

 The method of calculation is correct. The unusual duration of 

 the experiments (up to 50 hours) must have occasioned mixing 

 by diffusion and convection. The solvent was in all cases pure 

 methyl alcohol.
