III. 0.1386 gr. of the substance yielded a distillate of ammonia 



which required for neutralization 12.32 c.c. of decinormal acid. 



IV. Similarly 0.1180 gr. of the substance required 10.46 c.c. of 



decinormal acid. 

 V. 0.1599 gr. of the substance gave 0.1371 gr. of argentic bromide. 

 VI. 0.2414 gr. of the substance gave 0.2063 gr. of argentic bromide. 

 VII. 0.1 678 gr. of the substance gave 0.1429 gr. of argentic bromide. 

 VIII. 0.2062 gr. of the substance yielded on combustion 0.0403 gr. 

 of carbon dioxide. 

 IX. 0.2435 gr. of the substance yielded on combustion 0.0469 gr. 

 of carbon dioxide. 



These analyses were made from several different samples (especially 

 v., VI., and VII., which were all different), and hence they prove 

 the definiteness of the compound. The averaged results are given 

 below.
