ridl'i'jutd. bonate of potafli. A current of oxymuriatic acid gas was made 



to pafs through thefe bottles in the ufual way. The procefs 

 lafted a confiderable time. The firft bottle was foon filled 

 with the greenifh fumes of the gas ; the fulphur gradually be- 

 came moift and doughy, and the particles of it which adhered 

 to the fides began to trickle down in drops ; its colour changed 

 to orange, and at lafl:, a fine red liquid made its appearance. 

 The whole of the fulphur was gradually converted into this 

 liquid. I then ftopt the procefs. Abundance of gas had 

 paffed through all the bottles : the water in the fecond was, at 

 one time, quite milky, but it recovered its tranfparency before 

 the procefs was finifhed. Dots of fulphur were depofited 

 along the glafs tubes vvhich conneiSled the firft and fecond 

 phials; but none in that which conneded the fecond and third, 

 the folution in the third phial efFervefced precifely as in the ufual 

 procefs for preparing hyper-oxymuriate of potafh. The gas 

 which efcaped was carbonic acid. No oxymuriatic acid gas 

 could be diftinguilhed by its fmell in the fmall capfule of water 

 into which a tube ifiuing from the third bottle was plunged.

 double the vi'hat adhered to the fides of the bottle ; its fpecific gravity 



fulphur. was 1.623. It amounted, therefore, to 2.63 ounces, or more 



than twice the weight of the fulphur, exclufive of what had 



been volatilized during the procefs. 

 It is green by Sulphureted muria*ic acid is perfectly liquid; its colour is a

ftrcaks of it run down the infide of the phial, they appear 



green by tranfiuitted light.
