First (only) edition, with the Objections and Addition, rarely found together. The Essay on the probabilities of the duration of human life is one of the major books in the history of statistics and probability theory. Deparcieux had studied various schemes for life insurance, including that developed by the Neapolitan banker Lorenzo de Tonti, whereby upon the death of a participant his share (or only its dividends) is distributed to the remaining members. For the construction of mortality tables Deparcieux studied the life expectancy of members of restricted groups like religious communities, in order to exclude the effects of migration. His tables were used in France for decades.
Deparcieux was a scientist and mathematician, member of the French Academie des Sciences and professor at the Collège de France. He was also a mechanical engineer with particular interest in hydrodynamics and as such best known for his project for the supply of water for Paris, the Canal de l'Ourcq, carried out during the Empire.
