Glass measuring cylinder, England, 1777

The inscription on the funnel mouth of this measuring cylinder reads “No.10 for Dr. Haygarth Chester w Fecit 1777”. Fecit means “made”. This type of in-scription on laboratory glassware is rare. The cylinder has a scale etched and painted on the side and is marked with Roman numerals. This may have been used to measure liquids. “Dr Haygarth” may be John Haygarth (1740-1827), a physician based in Chester, north-west England. Haygarth researched the spread of smallpox and was partly responsible for the founding of the Small-pox Society in Chester in 1778.
