A minimum-maximum thermometer, taken from Japan during World War II. It was donated by John B. White, M.D., in January 1945. The instrument is in a finished wood case measuring 22.5 x 5.5 cm. The case lid bears Japanese characters in black ink, and a metal plaque is affixed to the inner lid. The case has a metal clasp and rope handle. The thermometer is housed in a black plastic tube 20 cm in length. A long slit down the tube vertical allows the gauge to be seen. The thermometer is sealed into the tube, though both tube end screw off. The units are Centigrade. The tubes are held into the box by pivoting wooden stays. One of the thermometers is missing, and the bottom of the case has been cracked and repaired.
ca. 1939-1945
