386 PHYSIOLOGICAL REMAINS. 



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

 pots, &c. then for the wars, as ordnance, portcullises, 

 grates, chains, &c. 



Note ; the finer works of iron are not so probable to 

 be served with such a stuff; as locks, clocks, small 

 chains, &c., because the stuff is not like to be tough 

 enough. 



For the better use in comparison of iron, it is like 

 the stuff will be far lighter : for the weight of iron to 

 flint is double and a third part ; and, secondly, it is 

 like to rust not so easily, but to be more clean. 



The ways of trial are two. First, by the iron and 

 stone of themselves, wherein it must be inquired, what 

 are the stones that do easiliest melt. Secondly, with an 

 additament, wherein brimstone is approved to help to 

 the melting of iron or steel. But then it must be con- 

 sidered, whether the charge of the additament will not 

 destroy the profit. 



It must be known also what proportion of the stone 

 the iron will receive to incorporate well with it, and 

 that with once melting ; for if either the proportion be 

 too small, or that it cannot be received, but piece-meal 

 by several meltings, the work cannot be of value. 



To make proof of the incorporating of iron and brass. 

 For the cheapness of the iron in comparison of the 

 brass, if the uses may be served, doth promise profit. 

 The doubt will be touching their incorporating; for 

 that it is approved that iron will not incorporate neither 

 with brass nor other metals of itself by simple fire : so 

 as the inquiry must be upon the calcination, and the 

 additament, and the charge of them. 



The uses will be for such things as are now made of
