I found a curious piece of glassware in an old medical lab that was 
being shut down, and which I was scrounching through for equipment.

It is essentially a U-tube, with one upright column, closed at the
top, with descending graduations of 0.01, 0.02, 0.03 'grammes'.
The other tube bulges out at the base to form a bell, with an open
lip about an inch across at the top.  The whole thing looks quite like
a little glass saxophone.

Nobody at all can tell me exactly what it is or how it was used,
although I suspect its use is something that would make second-graders
giggle insanely.  To whit, my employer, Dr. Dwight Miller, has pro-
nounced it "A piss-cup!"

Thank you, Dwight.

The only clue is the word "ureometer" etched on the upright column.
It still doesn't tell me what it measures, or how that measurement is
done.  Can anyone elaborate?
