Oxiia))iidosiilp]ionate.'i. — In our last paper, we had to call attention 

 to the discordance between some of the results of the work done by 

 otliers aiid by <)urselves on sulphazotised salts. We are glad to be able 

 to brino- in sup{>ort of the accnracy of certain of our own statements 

 the te-itimony of one of the other workers, Hr. Dr. Rascliig', who 

 wr«jte soon after the appearance of the paper on oxyamidosulphonates 

 tous request wlien next publishing to make known that he now entire- 

 ly agrees with our account of the decomposition of oxyamidosulpho- 

 nates bvcnustic alkali (J. Coll. Set., 3, 218), and withdraws his own 

 statement concerning it, which was based upon qualitative reactions 

 only.
