The next time, to avoid the formation of acetic ether, the 
substances were heated with glacial acetic acid at 160°. The 
whole product was sodium dinitrophenylate. Hence probably,

tadicals. Thus dinitrobrombenzol reacts easily with ammonia, 
but with potassium nitrite or sodium acetate there is no analo- 
gous reaction. By inversion it naturally follows that in aniline 
the amido-group must be rendered much more stable by the 
Introduction of nitro-groups. This is shown to be so by the 
ct that while aniline is most violently acted on by amylnitrite, 
tnitroaniline remains, under the same treatment, utterly un- 
affected,

than fifteen feet, and perhaps less than ten. It w 
hounced,t as a consequence of this fact, that the high terraces 
of Stratified drift about the heads of the estuaries and along 
the river valleys could not have been made by salt water, and 
‘aust have been due to the freshwaters of the enormously
