VII. Manufacture of Pianoforte Wire. 

 (To the Editor of the Annals of Philosophy.) 



SIR, London, Oct. 8, 1823. 



I should feel much obliged to you, or any of your correspondents, 

 for the communication of any particulars respecting the manufacture 

 of pianoforte wire, and the cause of the very decided superiority of 

 what is called Berlin steel wire over all that is made in England. Have 

 any of the new alloys of steel and silver, &c. or has Mr. Brookedon's 

 method of drawing through conical holes made in diamonds, rubies, 

 sapphires, or other hard stones, been tried, to make pianoforte wire ? 

 Considering the great quantity and value of the wire used in musical 

 instruments, made in the greatest perfection in this country, it is to be 

 lamented that our wire-drawers suffer themselves to be excelled by 

 foreigners. 



What mode of whitening brass wire will best preserve it from oxi- 

 dizement, and least injure its elasticity? 



I am, Sir, your constant reader, M. A.
