<;8 Mr. kir wan’s Experiments and Obfervations on 
thefe clecompofitions are conftantly indicated by the balance of 
affinities exhibited as above. 
In the lame manner filver is precipitated from the vitriolic acid 
by marino neutral fafts, whether their bafis be alkaline, terrene,, 
or metallic, as I have found on trial, and as the balance of 
affinities requires. 
lire nitrous folution of lead is aifo decompofed, and the- 
lead for the moft part precipitated (unlefs the folution be very 
dilute) in the form of vitriol of lead by all the vitnolico neutral 
falts ; and alfo by all the marino neutral falts, except marine 
fait of fiver, which only precipitates it by virtue of its excels 
of acid. 
The marine folution of lead is decompofed by all vitriolico 
neutral falts, except felenite and vitriol of nickel, which can- 
only precipitate it by virtue of an excels of acid. 
The nitrous folution of mercury is alfo decompofed, and the 
mercury for the moft precipitated in the form of vitriol of 
mercury by all vitriolic neutral falts, except vitriol of lead,, 
which, can only decompofe it by an. excels of acid. 
Nitrous folution of mercury is alfo decompofed by marino 
neutral falts, except the marine fait of filver and lead, which* 
can only affeblit by an excels of acid. 
Vitriol of mercury is alfo decompofed by marino neutral 
falts, which decompofition is alfo apparent by expofing the an- 
tagonifi: powers ; yet a precipitation does not always appear as I 
have remarked, particularly when marine allum is ufed, which 
1 attribute to the facility with which a fmall quantity of the 
marine fait of mercury is loluble in an excels of acid. Marine 
fait of filver decompofcs vitriol of mercury, only through its 
excels of acid.
