(10) Berzelius admits the existence of three compounds of chlorine with phos- 
phorus, which he calls the phosphoric chloride, phosphorous chloride and phospho- 
rie chloruret. The first is analogous to phosphoric acid in the proportions of its ele- 
ments, the second to phosphorous acid, and the third to an oxide of phosphorus. 
These explanatory remarks are made in accordance with the peculiar views of Ber- 
zelius in relation to the composition of the acids of phosphorus.— Trans. 
(11) Several metals, when finely divided and thrown into chlorine, become heated 
to redness in the act of combining with the chlorine. These compounds are called 
chlorides when the body united to the chlorine is electro-negative, and chlorurets 
either when the same body is electro-positive, or when, being electro-negative, the 
proportions in which the bodies combine correspond to an oxide. (Vol. i, pp. 276, 
277.)—Trans. 
* The right hand column contains the names according to the nomenclature in 
common use, when they differ from those which I use. The synonymes are from 
the fifth edition of Thenard’s Chemistry.—Berzelius. 
(12) For the synonymes of the original, those to be found in the fonrth American 
edition of Turner’s Chemistry have been substituted.— Trans. 
(13) The composition of the compounds of nitrogen with oxygen is, according to 
Berzelius—nitrous oxide, two volumes of nitrogen and one of oxygen; nitric oxide, 
two volumes of nitrogen and two of oxygen. His nitrous acid is the hyponitrous 
acid of most of the French and English chemists; the nitrous acid of those chemists 
Berzelius does not regard as a distinct acid, although he admits its composition to be 
two volumes of nitrogen and four of oxygen, which would place it next below ni- 
trie acid. The reason given for this view, is that there is no satisfactory evidence 
that this nitrous acid combines, either directly or indirectly, with bases, to form 
salts; the bases, on the contrary, resolve it into nitrous acid (hyponitrous) and ni- 
tric acid,— Trans.
