You're correct, of course Jack.  In fact I hesitated over taking this very
license while writing the article.  But I ask you to consider that, just as
the thermometer would need re-labelling to generate T, so too (most
probably) would the instruments measuring V and P.  They probably directly
measured a height and the difference in two mercury thread lengths (a gauge
pressure).
