composition, and the quotient will be the rate of the com- 

 pound required.

is often mixed with some baser metal, which is called the alloy, 

 and the mixture is said to be of so many carats fine, according to 

 the proportion of pure gold contained in it : thus, if 22 carats of 

 pure gold and 2 of alloy be mixed together, it ii said to be 22 ca- 

 rats fine. 



■If any one of the simples be of little or no value with respect 

 to the rest, its rate is supyosed to be nothing, as water mixed witli 

 wine^ and alloy with gold or silver.
