 I have a question about an old fashioned subject. As an undergraduate
 in pharmacy, I recall using a "gravimetric factor" in a formula which
 included the barometric pressure and temperature to compensate for the
 buoyancy of air upon a sample being weighed for quantitative analysis.
 As part of some other work, I wish to review this subject and I have not
 readily found a recent reference; although I have seen some tables. I
 wonder whether this correction is still done and where it is described
 in "prose."  Thanks.
