Nadar, Paris). Founder of thermochemistry and the science of explosives. He synthesised acetylene and bensene from their elements, and alcohol from ethylene, studied the polyatomic alcohols and acids, the fixation of nitrogen, the cbemistiy of agriculture, and the history of Greek, Syriac, Arabic, and medieval chemistry. He was a Senator of France, Minister of Public Instruction, Minister of Foreign Affairs, and Secretary of the Academy of Sciences, and is buried in the Pantheon at Paris. 

Reports on H2S emissions from common mineral soils are not very consistent and in part contradictory. For example, Bloomfield (1969) and Siman and Jansson (1976) detected the evolution of H2S from water-logged soils amended with sulfate and incubated under nitrogen atmosphere, whereas Banwart and Bremner (1976), who studied 25 soils from Iowa, failed to detect H2S under any conditions, even the most favorable ones. The latter authors ascribe the lack of H2S emission to sorption by the soils, possibly accompanied by fixation as FeS. The field measurements of Jaeschke et al. (1978, 1980) indicate that normally aerobic soils absorb H2S rather than emit it. Farwell et al. (1979), who studied agriclutural, forest, and marsh soils, also found only the last type to emit measurable quantities of H2S. Delmas et al. (1980), by contrast, found H2S to evolve from various soils in France, whose classification was not given but that cannot have differed much from those studied by Jaeschke et al. (1978).
