acetone-water mixtures . 



DISCUSSION. 



A parallel investigation of the viscosities and fluidities of solutions 

 of the several salts studied has been carried on in connection with the 

 conductivity side of the problem. 



We have measured the viscosities of the tenth and half normal 

 solutions of rubidium chloride, bromide, iodide, and nitrate, in all the 

 various mixtures of acetone and water used as solvents; also the vis- 

 cosities of the quarter, three-quarters, and whenever possible the normal 

 solutions of the same salts in the mixtures designated as 75 per cent, 

 50 per cent, and 25 per cent acetone with water. It was not possible 

 to obtain data on solutions of these salts in pure acetone, on account
