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.
