[main text]
Two parts of tin and one of bismuth form
Tutenag.
Ten Ounces of lead, six of bismuth, and
four drachms of regulus of antimony, form
a hard close-gramed metal, as white as silver.
Copper and tin foiled together in a solution
of tarter, or of tart, alum, and salt, the copper
will acquire a thin coating from the tin.
The Chinese metal, called packsong, is 
composed of copper, nicknel, and Zink.
