'His Physica Subtcrranea was the iirst attempt made to bring physics and chemistry into close relation '. It also 

 contains the author s theory of three earths of which all inorganic bodies should consist, viz. the mercurial, the vitreous, 

 and the combustible (terra pinguis). Combustion he explains on the assumption that when substances were burned or 

 metals calcined, the terra pinguis escaped. Starting from this conception GEORG ERNST STAHL, the editor of the above, 

 developed the PHLOGISTON THEORY, which so successfully hindered the progress of chemistry in the XVIIIth Century.
