would be dissolved, and there would be a liquid of another species.
But if liquid of the same species were added, of instance, wine with
wine, the same species would remain, but the wine would not be the
same numerically, as the diversity of the accidents shows: for
instance, if one wine were white and the other red.

But if the liquid added were of such minute quantity that it could
not permeate the whole, the entire wine would not be mixed, but only
part of it, which would not remain the same numerically owing to the
blending of extraneous matter: still it would remain the same
specifically, not only if a little liquid of the same species were
mixed with it, but even if it were of another species, since a drop
of water blended with much wine passes into the species of wine (De
Gener. i).

Now it is evident that the body and blood of Christ abide in this
sacrament so long as the species remain numerically the same, as
stated above (A. 4; Q. 76, A. 6, ad 3); because it is this bread and
this wine which is consecrated. Hence, if the liquid of any kind
whatsoever added be so much in quantity as to permeate the whole of
the consecrated wine, and be mixed with it throughout, the result
would be something numerically distinct, and the blood of Christ will
remain there no longer. But if the quantity of the liquid added be so
slight as not to permeate throughout, but to reach only a part of the
species, Christ's blood will cease to be under that part of the
consecrated wine, yet will remain under the rest.

Reply Obj. 1: Pope Innocent III in a Decretal writes thus: "The very
accidents appear to affect the wine that is added, because, if water
is added, it takes the savor of the wine. The result is, then, that
the accidents change the subject, just as subject changes accidents;
for nature yields to miracle, and power works beyond custom." But
this must not be understood as if the same identical accident, which
was in the wine previous to consecration, is afterwards in the wine
that is added; but such change is the result of action; because the
remaining accidents of the wine retain the action of substance, as
stated above, and so they act upon the liquid added, by changing it.

Reply Obj. 2: The liquid added to the consecrated wine is in no way
mixed with the substance of Christ's blood. Nevertheless it is mixed
with the sacramental species, yet so that after such mixing the
aforesaid species are corrupted entirely or in
