AND ON THE CONSTITUTION OF HYPONITRIC ACID. 429 
of the two higher oxides than that of this regenerating substance ; 
by that of cenanthic and azoleic acids; by that of oil of bitter 
almonds and of the sulpho-picroamyle ; by the composition, pro- 
perties and circumstances attending the formation of xanthic 
oxide and uric acid; by the analogy of constitution of several 
chlorides of compound radicals without any amount of oxygen, 
and of oxides of the same radicals ; by those of indenigene and 
the oxide of indene; by the oxides of isatene; by the action of 
hydrosulphuric acid upon the nitrites of the protoxides of naph- 
thaline and benzine, whence 
(C?°H70 + NO’) + 6HS = (CH? + Ad) + 4HO + 68, 
(C!?H°O + NO’) + 6HS = (C” H® + Ad) + 4HO + 68, 
amidides of the radicals of the bases of these salts result. 
Lastly, it is well known to every chemist that the constitution 
of the compounds derived from cacodyle were foreseen and 
pointed out by the celebrated Swedish chemist, at a time when 
these compounds were thought to possess a totally different 
constitution to that at present assigned to them, and that 
Bunsen was thus induced to endeavour to isolate the radical. 
34. However, this hypothesis, although it has a number of facts 
in its favour, cannot be generally correct, as it starts from the 
law admitted in organic chemistry, that each oxidized compound 
of the first order is the oxide of a radical, a law which does not 
hold good for the compounds Wo O? Cl, Ur? O? Cl, Cr O? Cl, 
(KO Cr O? + Cr O? Cl), SO? Cl, (SO? Cl + SO%), and in many 
other combinations. And for this reason, Berzelius, in order not 
to come in opposition with his hypothesis, has considered these 
bodies notwithstanding most beautiful analogies as compounds 
of the second and third order. The combination of Prof. Henry 
Rose, for instance, is composed, according to the Swedish che- 
mist, of sulphuric acid and chloro-sulphuric acid, 
3(SO? Cl + SO’) = SCI> + 580%. 
And Peligot’s salt of 
(KO Cr O08 + Cr O? Cl) = (KCl + 2Cr O°). 
With respect to the acid of M. Pelouze, it might be regarded as 
possessing an analogous composition to the sulphate of nitric 
oxide; but since I have proved that sulphuric acid enters into 
no combination with nitric oxide and sulphurous acid acts the 
part of a radical towards sulphur, we are compelled to look upon 
these combinations as having, like oxy-nitro-sulphuric acid, an 
analogous composition to the oxy-sulpho-sulphuric acid.
