pages 309-310, where the numbers representing analyses indicate
the nitrogen contents as usually reported in France, namely,
cubic centimeters of nitric oxide per gram of nitrocellulose. When
the numbers are printed m italics, the samples which were taken
for analysis were actively giving off red nitrous fumes
Diphenylnitrosamme, which is always present in powders made
from diphenylamine, is decomposed at 110°, and that temperature
therefore is not a suitable one for a study of the stability
of smokeless powder At 75° diphenylnitrosamme attacks nitrocellulose
less rapidly than diphenylamine itself, but this is not
true at lower temperatures (40° and 60°) at which there is no
appreciable difference between the two substances. Carbazol at
110° is an excellent stabilizer but at 60° and 75° is so poor as to
