Object Details
- Description
- Mercury-in-glass thermometer with a small bend in the stem just above the cylindrical bulb. The stem has a milk-white back; the front is marked "B22580" and carries the N/Z monograms; and is graduated (but not numbered) every degree F. from -50 to +125. The thermometer is mounted on a white porcelain plate marked "B22580" and "NEGRETTI & ZAMBRA, LONDON" with the N/Z monogram of the firm. The plate is graduated every 5 degrees Fahrenheit from -50 to +120. This, in turn, is mounted on a wooden base with metal guards protecting the bulb, and two metal loops so that it can be hung horizontally.
