Clinical thermometer with metal case and attached chain, English, 1885-1900
Clinical thermometers differ from ordinary thermometers in that they only measure a limited temperature range. There is also a small constriction above the bulb. This prevents the mercury dropping back after the temperature has been taken. The typical, small modern pocket type was devised by Sir Clifford Allbutt (1836-1925) in 1867. This European example dates from the late 1800s. It comes in a delicate carrying case with a screw top lid. The case can attach to clothing by a small brass pin.
