PHYSIOLOGICAL REMAINS. 191 



copper should be dearer than the brass itself, yet the 

 pleasure will advance the price to profit. 



First therefore for statue-metal, see Pliny s mix 

 tures, which are almost forgotten, and consider the 

 charge. 



Try likewise the mixture of tin in large propor 

 tion with copper, and observe the colour and beauty, 

 it being polished. But chiefly let proof be made of 

 the incorporating of copper or brass with glass- 

 metal, for that is cheap, and is like to add a great 

 glory and shining. 



For bell-metal. First, it is to be known what 

 is the composition which is now in use. Secondly, it 

 is probable that it is the dryness of the metal that 

 doth help the clearness of the sound, and the moist- 

 ness that dulleth it ; and therefore the mixtures that 

 are probable, are steel, tin, glass-metal. 



For string-metal, or trumpet-metal, it is the 

 same reason ; save that glass-metal may not be used, 

 because it will make it too brittle ; and trial may 

 be made with mixture of silver, it being but a deli 

 cacy, with iron or brass. 



To make proof of the incorporation of silver and 

 tin in equal quantity, or with two parts silver and 

 one part tin, and to observe whether it be of equal 

 beauty and lustre with pure silver ; and also whe 

 ther it yield no soiliness more than silver ? And again, 

 whether it will endure the ordinary fire which 

 belongeth to chafing-dishes, posnets, and such other 

 silver vessels ? And if it do not endure the fire, yet 

 whether by some mixture of iron it may not be made
