tendency is to form the monobasic oxyiodicle. The oxide of lead 

 previously formed reacts upon the ammonium iodide, forming lead 

 iodide and setting free ammonia. 



In the case of the action of ammonia on lead chloride as exam- 

 ined by Mr. Wood (see this Journal), it seems that the oxychloride 

 formed is not dependent upon the time of heating, but a definite 

 oxychloride is formed whether heated six, ten or fifteen hours, pro- 

 vided the chloride is kept covered with an excess of ammonia. If 

 by active boiling on the sand-bath the ammonia solution becomes 

 too much weakened, then a definite oxychloride is formed, indepen- 

 dent of the number of hours the solution is heated. Some of Mr. 

 Wood's experiments were repeated to test these conclusions.
