As in the case of amylaniline, the phenylic alcohol and the alcohol 

 are converted into nitrophenasic acid and nitrite of ethyl ; the am- 

 monia being in both cases partially oxidized. 



5. Action of Binoxide of Manganese and Sulphuric Acid on Aniline. 

 Aniline was dissolved in an excess of dilute sulphuric acid (1 part 

 of acid to 6 of water) and heated to boiling, when a small quantity 

 of binoxide of manganese was added. The reaction was allowed to 

 continue for 3 or 4 minutes, and it was stopped by cooling the flask 

 in water. Potash was then added, and the solution filtered. The 

 filtrate was distilled as described in experiment 2, and the distillate 

 evaporated to dryness with hydrochloric acid, and extracted with ab- 

 solute alcohol, to dissolve any chloride of aniline present. A plati- 

 num-salt made from the chloride, insoluble in absolute alcohol, gave 

 44 '0 per cent, platinum, which corresponds to the platinum in the 

 chloroplatinate of ammonia. 



6. Action of Binoxide of Manganese and Sulphuric Acid on 



Diethylaniline. 



Diethylaniline was treated in the same manner as aniline, but only 

 for about one minute. Potash was added, &c., as in the foregoing 

 experiment. The platinum-salt partially precipitated, as in Ex- 

 periment 4, from the chloride soluble in absolute alcohol, gave : 



Precipitate No. 1. Precipitate No. 2. 



37' 6 per cent. 35*4 per cent, platinum. 



No. 1 appears to be only a mixture of the chloroplatinates of 

 ethylamine and diethylamine ; the quantity of salt first precipitated 

 being too small to be properly recrystallized (on account of former 

 experiments showing that the quantity of ethylamine present was 

 very small). No. 2 corresponds with diethylamine, and of this salt
