‎First printing of Ingenhouz's memoir in which he shows a new way to make inflammable air. - Ingenhouz is most widely known for his discovery of photosynthesis which he published in the same year as the offered paper (1779).""An interesting paper written from the point of view of a phlogistonist and dealing with the forces of explosions of air or oxygen and ether vapour. Contains frequent references to Priestly and also to Lavoisier, Cavendish, Fontana.""(Duveen, p. 305).""In 1779, Jan Ingenhouz, also reported new ways of making inflammable airs. He had learnt the first method from John Cuthberson and Hendrik Aeneae on a visit to Amsterdam in 1777...When he returned to London, he tried to find simpler ways of generating the air so that it could be used as a substitute for inflammable air from metals in Volta's inflammable air pistol. He devised a way of volatising ether (Diethyl ether) for this purpose, but he thought that these to airs were the same.""(Leslie Tomary).‎
