that, under certain circumstances, the Metals may lie above 

 the Earths and Combustibles, when in a divided state. 

 Thus it is lighter than water in this porous form, although 

 its solid specific gravity in comparison to that of Water i3 

 as 4*315 to 1000 : so that, in judging of specific gravity, 

 the solid state of the substance must be attended to.
