ANTIMONY. 43 



the preceding paragraphs, it will be obvious that 

 the protoxide must be a compound of

 1 atom oxygen . 1 



6-5 



and its atomic weight must be 6v5. 



Thus it appears, that the atom of antimony 

 weighs 5*5 ; that the protoxide is a compound 

 of 1 atom metal + 1 atom oxygen, and the per- 

 oxide of 1 atom metal + 2 atoms oxygen. The 

 deutoxide may be considered as a compound of 

 1 integrant particle of protoxide and 1 integrant 

 particle of peroxide. For

1 atom protoxide consists of 5-5 + 1 

 1 atom peroxide . . 5-5 + 2

or we may consider it as a compound of 2 atoms 

 metal and 3 atoms oxygen. 



The only chemical compound of this deutox-

ide, or antimomous acid as Berzelius calls it, 

 hitherto examined, is antimonite of potash. Ber- 

 zelius obtained this salt by fusing together deut- 

 oxide of antimony and potash, washing off the 

 excess of potash by cold water, dissolving the
