PHYSIOLOGICAL REMAINS. 213 



Lastly, it is to be inquired, how the metal restored, 

 differeth in any thing from the metal rare : as whe 

 ther it become not more churlish, altered in colour, 

 or the like. 



Dr. Mcverel s answers touching the restitutions of 

 metals and minerals. 



REDUCTION is chiefly effected by fire, wherein if 

 they stand and nele, the imperfect metals vapour 

 away, and so do all manner of salts which separated 

 them &quot; in minimas partes&quot; before. 



Reduction is singularly holpen, by joining store 

 of metal of the same nature with it in the melting. 



Metals reduced are somewhat churlish, but not 

 altered in colour. 



THE LORD VERULAM S INQUISITION 



Concerning the versions, transmutations, multiplications, 



and ejfections of bodies. 



EARTH by fire is turned into brick, which is of 

 the nature of a stone, and serveth for building, as 

 stone doth : and the like of tile. Qu. the manner. 



Naphtha, which was the bituminous mortar used 

 in the walls of Babylon, grows to an intire and very 

 hard matter like a stone. 



In clay countries, where there is pebble and 

 gravel, you shall find great stones, where you may 

 see the pebbles or gravel, and between them a sub 

 stance of stone as hard or harder than the pebble 

 itself.
