"squashed" gaskets as centerpieces

Howdy folks!  Arthur, first of all we used the squashed gaskets and other
thin plastic only for absorbance work, which I think can get you some
reasonable data.  For interference data I fully agree.  But when you say
for interference, "high gradient" do you mean absolutely or relatively?
Obviously you are implying the former.  It would seem natural that one would
run in a thinner cell to reduce the apparent gradient--but I think you are
saying that doing this does not help.  That so?   Emory
