About this Item
A chemist, Pierre Antoine Favre (1813-1880), conducted study into thermochemistry, and along with others, pioneered various instruments such as a focometer and a pyrometer. This title is concerned with the production of electricty and batteries for storage. Large 4to: orig. printed wrapps. 1 blank, 1 leaf (half-title), (i-iii), 184 pp, 1 blank, figures, tables. Presentation copy from the author; library stamps on front cover, half-title and title pages; some foxing, slight soiling. Favre (1813-1880) was Professor at Marseilles (1856; appointed Dean of the Medical Faculty, 1872) and pioneer in conservation of energy (electrical & heat) (Partington IV: 610-613; 691-693) A very thorough discussion of Favre (in English): J. Wisniak, Revista CENIC Ciencias Quimicas, Vol. 41 (No. 2), pp 131-143 (2010). Beginning in 1844, Favre and Johan Theobold Silbermann (1829-1905) made numerous ground-breaking thermochemical studies. Favre s mercury (water) calorimeter (see a description including its operation: E.L. Nichols, A Laboratory Manual of Physics and Applied Electricity, Vol. II, New York, MacMillan, 1894, pp 245-251). Favre and Silbermann corrected errors in the work of Dulong and Petit and accurately verified (1857) Joule s findings on the mechanical equivalent of heat. Studies on heats of reaction was based on chemical equivalents. Their studies also proved the differences in energy between allotropes. Their study of the enthalpy difference between CO and CO2 was important for correcting combustion studies. Inscription reads: "Maurice Rohier Prof. GuĂ rin / Hommage dauteur". Provenance: From the collection of Arthur Greenberg and a municipal library in Brittany.
