 BFNO, of bismuth. 



The succeeding tables present lists of the principal ter-oxygen and 

 tetra-oxygen mineral acids. Some of these acids are known only 

 through the medium of their metal- and ethyl-representatives. 



Ter-Oxygen Acids. 



Tetra-Oxygen Acids. 



Hence the formula H^, Ry O^, will represent the general type for 

 an acid, where H, represents the atoms of hydrogen, which, save in 

 carbon compounds, are found to vary only from 1 to 4 ; where 

 Ry represents the acid radicle, that is the chlorine, or sulphur, or 

 phosphorus, or carbon, &c. which gives the special character to the 

 acid, and which, save in carbon compounds, is usually confined to 1 or 

 2 elementary atoms ; and where O^ represents the atoms of oxygen 

 which generally range from to 4, but occasionally extend to higher 

 numbers.
