758.8 nun. 58.7 gr. of the solution gave 0.5584 gr. of argentic 

 bromide. 



Action of Sodic Phenylate in Benzol. 



XXXI. Weight taken, 1.1227 gr. Weight of aqueous solution, 

 67.15 gr. 32.5 gr. of the solution gave 3 c.c. of nitrogen from 

 the sodic nitrite at a temperature of 29° and a pressure of 

 766.5 mm. 30.05 gr. of the solution gave 0.1568 gr. of argentic 

 bromide. 



The results of these experiments are collected in Tables III. and 

 IV. with those previously given by sodic ethylate. The first column 

 contains the sort of alcohol used and the number of the experi- 

 ment, the second the weight of tribromtrinitrobenzol used, the 

 third the percentage of nitrogen, and the fourth the percentage 

 of bromine removed, calculated in the way already described in 

 connection with Tables I. and II. 



TABLE III. — ExPERIMtNTS WITH THE ALCOHOL ALONE.
