Plate 3. Clement metallic thermometer - cross sectional schematic of the model at the Oceanographic Museum at Monaco. The model at the museum was constructed by Negretti and Zambra in 1912 after the original made in 1839 by Leander Clement, the clock maker of Rochefort. The thermometer functioned by comparing the expansion (or contraction) of two strips of different types of metal.
