combinations of Oxymuriatic Gas and Oxygene, &c. 31 
oxygene are stronger than for oxymuriatic gas. And from 
the experiments I have already detailed, iron and arsenic are 
analogous in this respect, and probably some other metals. 
Potassium, sodium, calciuth, strontium, barium, zinc, mer- 
cury, tin, lead, and probably silver, antimony, and gold seem 
to have a stronger attraction for oxymuriatic gas than for 
oxygene. 
I have as yet been able to make very few experiments on 
the combinations of the oxymuriatic compounds with each 
other, or with oxides. The liquor from arsenic, and that 
from tin, mix, producing an increase of temperature ; and the 
phosphuretted, and the sulphuretted liquors unite with each 
other, and with the liquor of Libavius, but without any re- 
markable phenomena. 
I heated lime gently in a green glass tube, and passed the 
phosphoric sublimate, the saturated oxymuriate of phosphorus 
through it, in vapour ; there was a violent action with the pro- 
duction of heat and light, and a gray fused mass was formed, 
which afforded by the action of water, muriate and phosphate 
of lime. 
I introduced some vapour from the heated phosphoric sub- 
limate, into an exhausted retort containing dry paper tinged 
with litmus: the colour slowly changed to pale red. This 
fact se is in favour of the idea that the substance is 
an ado but as some minute quantity of aqueous vapour 
might - been present in the receiver, the experiment can- 
not b> vded as decisive : the strength of its attraction 
for < . 0 h, is perhaps likewise in favour of this opinion. 
A! a\ muriates that I have tried, indeed form triple com- 
pound, with this alkali ; but phosphorus is expelled by a gentle
