In the first place this assumes a knowledge of the behaviour 
of silver dioxide with ammonia—a knowledge which Sifile had not 
derive m experience as he had found himself unable to pre- 
pare this dioxide of silver; and in the second place it is difficult to 
imagine what would be, on this hypothesis, the composition of the

Fess not react with ammonia according to the equation— 
I have not been able to confirm Siilc’s analytical figures for 
the reaction of the peroxynitrate with ammonia, and until the 
nature of the other products of the reaction has been ex xamined, } it

Other formulae which might be suggested to elucidate the
