j{g$ COMBINATION OF OXIMURIATIC GiS AND OXIGEX. 



5thly, The same observation applies to the difference of 

 solar and culinary heat; 



6thly, And in particular to the radiation oFeold. 

 7thly, The opinion oF capacity for caloric i& hypothetical ;

 conformity to the usual order of nature, in dispensing the 

 other properties of matter.

 offer some extraordinary and novel results.

time, to state the whole progress or this investigation. It 



will, I conceive, be more interesting, that I should immedi-

 by Members of this Body, belonging to the Committee of 

 Chemistry of the Royal Institution. 

 Its properties The oximuriatic gas prepared from manganese, either by 

 when pro- mixing it with a muriate and acting upon it by sulphuric 



cored by acid, or by mixing it with muriatic acid, is, when the oxide

inercJiry, uniform in its properties; its colour is a pale yel- 

 lowish green ; water takes up about twice its volume, and 

 scarcely gains any colour; the metals burn in it readily; it
