metal to the acid menstruum in the phial before he plunged
it into the under water; but it just now occurs which This is necessary where
the mix, the metal solvend is in powder, as it necessary must be
where the Acid Menstruum acts upon it but slowly as in the case <add> between Iron and the Vitriolic Acid and Iron. In
this case there is this inconvenience, that the
rapidity of the solution, could not if there was
occasion, be regulated. But it just now occurs
to me, that where the Acid Menstruum and the
Metal solvend are such as act briskly on each
other, this method is free from every disadvantage.
The Metal solvend may be dropped in in
pieces larger or smaller as shall be found
convenient: and when the process is over, if
the Menstruum is not saturated, the mixing-
phial may be corked again, and the Menstruum
serve for subsequent experiments
I should just now expunge all that I
have said of my own method; were it not that for
one advantage over the other it has still.
It is the only one of the two that is practicable in cases
where heat is necessary to be employed in order must be applied
to facilitate the solution.
One objection to his method, obvious as it is, never
occurred to me. I suppose it does not hold good
in practise or he would have mentioned it. It is,
that the water lying over the mixing phial might
get into it, and mix with the menstruum, so as to and dilute
it to such a degree as to impede the solution. This inconvenience
however if it arises, may be palliated at least
by making the neck of the mixing-phial narrow. I am unable
to determine a priori
whether the
attraction of gravity,
(the acid which is at
bottom being the heaviest)
would prevail so
as to keep them separate,
or the chymical
attraction so as to make
them mix.
