HENRY**, of a noble family in Languedoc, was born at Aramont in the diocese of Uzez, on the 29th of May 1695, and died there on the 27th of December 1771, aged 76. He learned the mathematics without a master, and went to Paris in 1718, where he formed a close friendship with the illustrious Reaumur. In 1724, he was admitted a member of the Royal Academy of Sciences at Paris, and in a few years rose to the degree of a pensioner. Besides a vast number of Memoirs printed in the collection of that society, he published in 1731 the Theory of the Working of Ships, in one volume 4to; a work of considerable merit, which was translated into English, and made the author be admitted into the Royal Society of London. In 1740, the states-general of Languedoc made choice of him for their chief engineer, and gave him at the same time the appointment of inspector general of the canal which unites the two seas. That province is indebted to him for several monuments of his genius, which will transmit his name with lustre to posterity. The city of Montpellier being in want of water, Pitot brought from the distance of three leagues the water of two springs which furnish a plentiful supply of that necessary article. They are brought to the magnificent Place du Peyron, and thence are distributed through the city. This astonishing work is the admiration of all strangers. The illustrious marshal de Saxe was the great patron and friend of Pitot, who had taught this hero the mathematics. In 1754, he was honoured with the order of St Michael. In 1735, he had married Maria Leonina Pharambier de Sabbaloua, descended of a very ancient noble family of Navarre. By this marriage he had only one son, who was first advocate-general of the court of accounts. PITOT was a practical philosopher, and a man of uncommon probity and candour. He was also a member of the Royal Society of Sciences of Montpellier; and his eulogium was pronounced in 1772 by M. de Ratte perpetual secretary, in presence of the states of Languedoc; as it likewise was at the Royal Academy of Sciences of Paris by Abbé de Fouchi, who was then secretary.
