Pocket barometer with mercury and alcohol, and tube, by Joseph Rankin Stebbing, Canute Road, Southampton, England, 1845-1855
Mercury barometers needed to have two tubes that were at least 33 inches long, and were generally cumbersome to carry around. To allow for readings of air pressure by a pocket instrument, a much shorter glass tube was doubled back on itself to fit a small case, and the moving agent was a combination of air, spirit and mercury. This example was made by Stebbing of Southampton.
