    On a Combination of Oxymuriatic Gas and Oxygene Gas* Read February 21, 1811. ISHALL beg permission to lay before the Society the account of some experiments on a compound of oxymuriatic gas and oxygene gas, which, I trust, will be found to illustrate an interesting branch of chemical enquiry, and which offer some extraordinary and novel results. I was led to make these experiments in consequence of the difference between the properties of oxymuriatic gas prepared in different modes ; it would occupy a great length of time to state the whole progress of this in- vestigation. It will, I conceive, be more interesting that I should immediately refer to the facts; most of which have been witnessed by Members of this Body, belonging to the Committee of Chemistry of the Royal Institution. The oxymuriatic gas prepared from manganese, either by mixing it with a muriate and acting upon it by sulphuric acid, or by mixing it with muriatic acid, is when the oxide of manganese is pure, and, whether collected over water or mercury, uniform in its properties; its colour is a pale yellowish green; water takes up about twice its volume; and scarcely gains any colour; the metals burn in it readily; it combines with hydrogene without any deposition of moisture: it does not act on nitrous gas or muriatic acid, or carbonic oxide, or sulphureous gasses, * [From Philosophical Transactions for 1811 vol. 101, pp. 155-162.]
