Tlie snlphin-, it will be seen, is ii little low for the formula, a deviation 

 attributable perhaps to the presence of a little K5 salt from the mother- 

 liquor. 



In this salt the oximidosulphonate exists one-third as normal 

 barium salt and two-thirds as dipotassium salt. In its formation the 

 Kg salt behaves, as usual, as mixed normal and dipotassium salts, of 

 Avhich one part of the former suffers decomposition with the barium 

 chloride and the other remains in solution, while the dipotassium salt 

 precipitates in combination with the barium salt : —

On addinp' to a warm concentrated solution of three mois, of the 

 K5 salt, one mol. of ])ariiun chloride, agitating to redissolve the 

 precipitate and then letting the solution cool, a relatively very large 

 cpiantitv of crystalline powdery precipitate is obtained, which from its 

 quantitv must consist largely of potassium salt. I'eing uncertain 

 concerning its freedom from sej^arate potassium salt we have not 

 analysed it. It can be redissolved in its warmed mother-liquor and 

 recovered bv coolino-, ao-ajn and ao-ain. Ihit if the mother-liquor 

 decanted is alMwed to stand some hours to deposit most of its 

 potassium salt and then re-decanted on to tlie barium precijntate it 

 fails to dissolve this Avhen warmed with it, though it effects great 

 change in its c(-)mposition, dissolving out ])otassiLun salt. Thu.s 

 treated, the pi-ecipitate was found to diffei- only a little from a salt 

 having the formula BaIvNS,,();, 1 LU and could be regarded as this 

 salt retaining unchanu'ed a little of the salt from which it liad been
