asicenain this, we have operated upon large quautities. Three cubic 



inches of sulphuretted hidrogen, allowi^d to [wss from a 



receiver with suitable stop-cocks into a tube containing 6 



cubic inc'hes of oximuriatic jj;as, inflamed as it entered ; % 



very tU^ht cloudiness was produced, whith soon disappeared?; 



«nd there was an immediate formation of oximuriate of 



sulphur, which condensed on the interior of the tube, and 



was not redissolvcd by the iBuriatie acid g»»> tWugh heat 



was applied. - '- ,, , - i. r. 



Precipitations [n respect to. Mr. Murray's results I have i^nly to, observe, 



barytesac- tbaj as he absorbed the muriatic acid gas by water ia the 



counted i9r, very vessel in which the experiment was made, the solution, 



thus formed, should, as it iudecid did, occasion a copicius 



precipitate with muriate of barytes. It is now a well 



known fact, that the sulphuric and muriatic acids are formed 



by thedecompositioji of oximuriate oi' sulphur by water. 



Habits ot 0x1- ]t may not perhaps be impertinent to the subject to 



suip'nnTGus state, that the relation of sulphurous acid gas to oxirtni- 



acidgas. riaticgas is precisely a naloe(ous to that" of th^ gsivseoijsoxid^ 



of carbon. I ascertainetl some months ago, that the two 



gasses previously dried admitted into an exhausted gltissglobe 



ijfmaiip together without any alteration taking pl«ce^^t5^ 



tfeat if a little water be present, muriatic adid gifelaiy^ 



sulphuric acid are quickly formed. * u^,. y. u v?^
