OF THE ATOMIC THEORY. 1<,'3 



though most of them combine, at least, with 

 muriatic acid. Hitherto, only a few of these 

 suboxides have been noticed by chemists, though 

 it is likely that they will increase considerably 

 hereafter. 



It is unnecessary to make any observations 7th 

 upon Berzelius's seventh law ; it expresses mere- 

 ly his opinion respecting the composition of acids. m 

 If the views which I have given in the following 

 pages be entitled to any confidence, it will be 

 seen that eleven of the acids contain three atoms 

 of oxygen ; namely, 



1 Oxalic 4 Arsenic 7 Succinic 10 Tungstic 



2 Sulphuric 5 Molybdic 8 Benzoic 11 Fluoboric. 



3 Chromic 6 Acetic 9 Formic 



Six contain only one atom of oxygen ; namely, 



1 Silica 8 Hyposulphurous 5 Columbic 



2 Phosphorous 4 Oxide of tellurium 6 Fluoric. 



Twelve contain two atoms ; namely, 



1 Carbonic 4 Sulphurous 7 Selenic 10 Uranitic 



2 Boracic 5 Titanic 8 Antimonic 11 Uric 



3 Phosphoric 6 Arsenious 9 Molybdous 12 Fluosilicic. 



Two contain four atoms ; namely, 



Manganesic and citric. 



Three contain five atoms ; namely, 



Hyposulphuric, tartaric, chloric.
