Add to album

This special barometer without mercury, also known as a sympiesometer, dates from around 1850. It was retailed by Richard Millar, an optician and clockmaker based in Leith, and may have been made locally.

The semicircular sympiesometer is combined with a semicircular mercury thermometer. The instrument is inscribed 'IMPROVED SYMPIESOMETER', perhaps as an attempt to evade patent restrictions.

Richard Millar is one of two possible people, father and son, who had a watch and clockmaking business in Edinburgh and Leith between 1814 and 1860. The younger Richard Millar took over the premises of a bankrupt Leith instrument retailer in 1852.
