Found in a cabinet in the donors' basement after they bought the house from John Briscoe of Briscoe's pharmacy which was located at 229 Princess Street in Kingston from 1954 to 1966; it is likely that Briscoe acquired the collection during his career as a pharmacists.
Internet; the number on the maker's mark (10) probably means that the bottle was made in 1910 based on similar marks on other Scottish bottles, but this is not known for sure.

John Briscoe took over Bishop's Drugs Ltd in 1954; Bishop owned another store at 528 Princess Street from 1946 to 1954 and it had been a drug store under other ownership from 1923 until 1946; this is a possible origin of some of the collection.

Blood pressure is measured and recorded using a sphygmograph. It is strapped to the wrist. The pulse beat is transmitted to a lever which records it on smoked paper. The first efficient sphygmograph was designed by Étienne-Jules Marey (1830-1904) in 1863. This example belonged to Dr Robert Ellis Dudgeon (1820-1904). He was a prominent figure in homeopathy. Dudgeon also made his own changes to Marey’s original design. It was made by instrument maker J. Gauter in 1876. In the late 1800s, physiology teachers used sphygmographs to visually demonstrate blood pressure. Instruments such as this were also valuable diagnostic aids. They were the predecessor of the modern arm cuffs physicians now use to measure blood pressure.
