430 K@NE ON THE NATURE OF 4QU4 REGIA, 
35. Benzamide, oxamide, salicylamide, phtalamide, and several 
analogous oxidized compounds, are compused, just like the oxi- 
dized combinations of the above class, of two radicals. The 
oxygen is therefore able to contribute to the formation of com- 
pound radicals, and these, by combining with oxygen, chlorine, 
sulphur, &c., may form oxy-acids, oxy-chloro-acids, oxy-sulpho- 
acids, oxy-bases, oxy-chloro-bases, oxy-sulpho-bases, and also 
compounds in which the oxygen, chlorine, or the sulphur acts 
both as acidifier as well as restorer of bases. 
But since chlorine or sulphur may behave as electro-nega- 
tive element towards an oxygeniferous radical, and oxygen is like- 
wise capable of acting the same part towards the same radical, 
it results that the entire amount of oxygen of an organic com- 
pound is not always consumed in the formation of bases and 
acids, in which neither chlorine, nor sulphur, nor any other body 
functioning as electro-negative element towards the radical, 
enters. 
The hypothesis of Berzelius, as well as the principle from 
which it is deduced, may consequently be sometimes deficient. 
A remarkable relation between two branches of science devoted 
to the study of bodies, which, without being of the same nature, 
are nevertheless formed and changed according to the same laws, 
the same principles, and frequently even according to the same 
theories! This it is indeed which gives a character of probability 
to the hypothesis of the Swedish chemist, which the opposite 
hypothesis does not possess, which assumes that the hyponitric 
acid may replace the hydrogen in a compound radical without 
its being capable of proving that this acid acts the part of a 
simple body. 
On the Constitution of Hyponitric Acid. 
36. The property of nitrous acid of combining with sulphuric 
acid, compared with that of the same acid of forming with nitric 
acid hyponitric acid, and the decomposition of the latter acids 
by bases, induced Berzelius at first to admit that this compound 
consisted of nitrous and nitric aeid. 
37. But when M. A. Rose announced that he had obtained 
the sulphate of nitric oxide, the Swedish chemist, in accordance 
with the German, considered the hyponitric acid to have an 
analogous constitution. 
As both these views do not correspond well with the law of
