The affinities of calces to phlogiflon are taken at a medium ; 
for a) mod: all metallic fubftances are capable of greater or lefier 
dephlogiflication, according to the fpecies, concentration, and 
dephlogilVication of their menflruum. The more they are 
dephlogiflicated, the greater their affinity to phlogiflon ; and, 
in general, the lefs their affinity to the mineral acids. Yet 
there is a point of dephlogiflication at which the attraction of 
acids to the calces is flrongell : thus the vitriolic acid attracts 
bifmuth moil flrongly after it has been dephlogiflicated by the 
nitrous acid ; and the marine acid attrads both bifmuth and 
nickel more powerfully, when dephlogiflicated by the nitrous 
or vitriolic acids. 
From thele data we may eafily conceive, in moft cafes, what 
will happen on putting one metal into the folution of another. 
Thus, if a piece of copper be put into a faturate folution of 
filver, the filver will be precipitated ; for the balance is in 
favour of the divellent powers.
