the metallic clilorides, into which they may be transformed by 

 losing their oxygen. 



When red oxide of mercury is boiled with solution of chlorine, 

 or when treated by a boiling solution of corrosive sublimate, a 

 black crystalline matter is obtained, which is a combination of the 

 red oxide, and the dentochloride of mercury. It is also formed 

 by precipitating a hot solution of corrosive sublimate by potassa, 

 not in excess. When analyzed it gave as its composition, 



5 atoms of deutoxide - 79.942 



1 atom of deutochloride - 20.058 



This compound, M. Granville remarks, tends to strengthen 

 the opinion, that the chlorides dissolve in water, without being 

 converted into muriates ; otherwise it must be admitted that 

 decompositions and recompositions of water are effected by very 

 weak causes, such as the affinity of chloride of mercury for 

 oxide of mercury, or the cohesion of the oxido-chloride. 



The precipitate obtained by pouring muriate of antimony into 

 water, is an oxido-chloride of antimony. It fuses without de- 

 composition, and is composed of 



Protoxide of antimony, 7 atoms 82.01 



Chloride of antimony, 1 atom 17.99 



The similar preparation of bismuth is also an oxido-chloride; 

 it has the same properties as the compound of antimony, and 

 when analyzed gave, as its composition, 1 atom chloride of 

 bismuth, 4 atoms oxide of bismuth. 



Chlorides combine with ammonia as well as with oxides. 

 The composition of the following three are given : — Ammonia 

 chloride of phosphorus, 



Chloride of phosphorus, 1 atom 63.502 



Ammonia, 7 atoms 36.498 



Ammonia chloride of tin, 



Chloride of tin, 1 atom 79.06 



Ammonia, 4 atoms 20.94 



Ammonia chloride of mercury, 



Deuto-chloride of mercury, 1 atom . . . 94.09 

 Ammonia 5.91 



Iodine appears to combine with oxides in the way that chlo- 

 rine does. The compound with lime and strontia appear each 

 to consist of one atom of the oxide, and one atom of iodine. 

 Those formed by oxide of zinc, potassa, Sfc, appeared to be 

 perfect ; but the compositioii is not given. 



In addition to what M. Gay Lussac has said of the combina- 

 tion of cyanogen with oxides, M. Granville adds that the hy- 

 drate of strontian instantly absorbed much cyanogen. Hydrate
