Q(\ E. DIVERS AND T. HAGA. 



chloride alono- with it. We give an example of the composition of 

 snch a salt, wliich was obtained in good transparent small rhombic 

 prisms : — 



Potassinm 7*45 



Sodium 1^-98 



Sulphur 23-65* 



Chlorine 0-03 



The potassium is to the sodium as K : Xa., pins a very little for the 

 chlorine. 



By dissolving dipotassium oximidosulj^honate in a warm con- 

 centrated solution of disodium oximidosulphonate. it is practically 

 certain from what precedes that a potassium-sodium sfdt would 

 crystallise out. We regret we have no experience to record on tliis 

 point. 



Ammonium oximidosiilplioiiales. 



Hydroxy -lead oximidosulphonate (p. (SO) yields at once, when 

 shaken with enough solution of ammonium acid-carbonate to convert 

 its lead to carbonate, a solution of normal ammonium oximidosul- 

 phonate almost pure. Barium oximidosulphonate may be used in 

 place of the lead salt, but not being basic it requires the normal instead 

 of the acid ammonium carbonate to be used with it. The solution 

 smells mildly of ammonia, but in a closed vessel may be preserved 

 unchanged. Heated with exposure to air, it becomes a solution of 

 the diammonium salt, l)y loss of ammonia. Guarding against hydro- 

 lysis, to whicli this salt is very liable, bv adding a drop of strong 

 solution of ammonia occasionally so as to maintain its alkalinity, the 

 solution of the diammonium salt may be evaporated on the water- 

 bath to an exceedingly small volume without decomposing. If. now, 



* This number is calculated, as the sulphur was lost.
