388 PHYSIOLOGICAL REMAINS. 



For the better use of the compound stuff, it will be 

 sweeter and cleaner than brass alone, which yieldeth a 

 smell or soiliness, and therefore may be better for the 

 vessels of the kitchen and brewing. It will also be 

 harder than brass, where hardness may be required. 



For the trial, the doubts will be two : First, the over- 

 weight of brass towards iron, which will make iron float 

 on the top in the melting. This perhaps will be holpen 

 with the calaminar stone, which consenteth so well with 

 brass, and, as I take it, is lighter than iron. The other 

 doubt will be the stiffness and dryness of iron to melt ; 

 which must be holpen either by moistening the iron, or 

 opening it. For the first, perhaps some mixture of lead 

 will help ; which is as much more liquid than brass, as 

 iron is less liquid. The opening may be holpen by some 

 mixture of sulphur: so as the trials would be with 

 brass, iron, calaminar stone, and sulphur ; and then 

 again with the same composition, and an addition of 

 some lead ; and in all this the charge must be con- 

 sidered, whether it eat not out the profit of the cheap- 

 ness of iron. 



There be two proofs to be made of incorporation of 

 metals for magnificence and delicacy. The one for the 

 eye, and the other for the ear. Statua metal, and bell 

 metal, and trumpet metal, and string metal ; in all 

 these, though the mixture of brass or copper should be 

 dearer than the brass itself, yet the pleasure will ad- 

 vance the price to profit. 



First therefore, for statua-metal, see Pliny 9 s mixt- 

 ures, which are almost forgotten, and consider the 

 charge. 



Try likewise the mixture of tin in large proportion
