Pat,    (01)

I'm traveling now, and I don't have my copy of the convenient
selection from Tarski's papers with me.  But he does not do
that in his 1933 paper or the more philosophical paper of 1944,
which is on my web site.    (02)

Where?  He certainly did not do so for "Snow is white", and I
could not find any other example.    (05)

Could you please go through any of the publications by Russell
or Quine and find one empirical example in which they started
with an empirical subject and specified the sets D and R of
the domain.  I realize that they did such things for mathematical
subjects, and I also realize that they have waved their hands
about for a lot of empirical issues.  And I also realize that
many people in comp. sci. and AI (e.g. Lenat) have specified
actual sets.  But please show me where Russell and Quine have
taken a single empirical subject (or even one complete sentence
in English) and specified the sets D and R.    (07)

Just saying that there exists unspecified sets D and R does not
constitute an example.  I'm not asking for all the detail, but
just one example, even a toy one, by Tarski.    (09)

In other words, they're hand wavers.  They did do the detailed work
for mathematical subjects, but if it was so "blindingly obvious" for
empirical subjects, why didn't they work out one serious example?    (011)
