1. Introduction. 
In the last communication which I had the honour of pre- 
senting to the Royal Society, I stated a number of facts, which 
inclined me to believe, that the body improperly called in the 
modern nomenclature of chemistry, oxymuriatic acid gas , has 
not as yet been decompounded ; but that it is a peculiar sub- 
stance, elementary as far as our knowledge extends, and 
analogous in many of its properties to oxygene gas. 
My objects in the present Lecture, are to detail a number 
of experiments which I have made for the purpose of illus- 
trating more fully the nature, properties, and combinations of 
this substance, and its attractions for inflammable bodies, as 
compared with those of oxygene ; and likewise to present 
h mcccxi. B
