PHYSIOLOGICAL REMAINS: 



Inquisitions touching the compounding of metals. 



To make proof of the incorporation of iron with 

 flint, or other stone. For if it can be incorporated 

 without over-great charge, or other incommodity, 

 the cheapness of the flint or stone doth make the 

 compound stuff profitable for divers uses. The 

 doubts may be three in number. 



First, Whether they will incorporate at all, other 

 wise than to a body that will not hold well toge 

 ther, but become brittle and uneven ? 



Secondly, Although it should incorporate well, 

 yet whether the stuff will not be so stubborn as it 

 will not work well with a hammer, whereby the 

 charge in working will overthrow the cheapness of 

 the material ? 



Thirdly, Whether they will incorporate, except 

 the iron and stone be first calcined into powder ? 

 And if not, whether the charge of the calcination 

 will not eat out the cheapness of the material ? 



The uses are most probable to be ; first for the 

 implements of the kitchen ; as spits, ranges, cobirons, 

 pots, etc. then for the wars, as ordnance, portcullises, 

 grates, chains, etc. , 



Note ; the finer works of iron are not so proba 

 ble to be served with such a stuff; as locks, clocks,
