Mr. Dalton has supposed, that thereIs a solid sulphuric acid formed by the action of sulphureousacid gtis upon nitrous acid gas. But I find, that when driedsulphureous acid gas and nitrous acid gas are mixed together,there is no action; but by introducing the vapour of water, they 7 Thilos.

I have referred, in the Philosophical Transactions, to the chlorine andcombination of chlorine and sulphur. I have been able to form compound of these bodies, which does not deposit sulphurby the action of water. When sulphur is satured with chlo-rine, as in Dr, Thomsons sulphuretted liquor, it appears tocontain, from my experiments, only 6^ of chlorine to 30 ofsulphur. 4. Some general Observations. It is a fact worthy of notice, that phosphoric and sulphuric Observations,acids should contain the same quantity of oxygen to the same tions^in°phos-quantity jof inflammable matter; and yet that the oxygen phoric andshould be combined in them, with such different degrees of ^Selamefaffinity.
