Soft cover. Condizione: Very Good. John Ingenhousz. (Jan Ingen Housz, Ingen-Housz). "Easy methods of measuring the diminution of bulk taking place upon the mixture of common air and nitrous air" in Phlilosophical Transactions of the Royal Society of London, printed by John Martyn, volume 66, 1776, pp 257-268. This copy has been cleaned up, with the spine nicely mended with Japan tape, and the whole being sewn-in to new wrappers of high-quality paper. VERY GOOD. Nice copy. [++] Ingenhousz's paper describes simple techniques for quantifying the volume change that occurs when common air and nitrous air (also known as nitric oxide) are combined, accurately measure the decrease in volume that results from the chemical interaction between the two types of air. (It also includes experiments on platinum ("Platina").) [++] Ingenhousz is best known for discovering photosynthesis by showing that light is essential to the process by which green plants absorb carbon dioxide and release oxygen. [++] It seems that this is Ingenhousz's second published paper.

Ingen-Housz's work on photosynthesis is thought to have been stimulated by Joseph Priestley's (1733-1804) Observations on different kinds of air (1772) in which he outlined the discovery that growing plants "restored" air depleted by combustion or animal respiration. In his work Ingen-Housen "advanced the understanding of the subject considerably. He established that only the green parts of a plant can 'restore' the air, that they do this only when illuminated by sunlight, and that the active part of the sun's radiation is in the visible light and not in the heat radiation. In addition he found that plants, like animals, exhibit respiration, that respiration continues day and night, and that all parts of the plant - green as well as nongreen, flowers and fruits as well as roots - take part in the process" (DSB). - Visit our website for additional images and information.

Paris, Théophile Barrois, 1780. 8vo. Fine cont. full mottled calf, richly gilt spine and gilt titlelabel in red leather. Edges gilt. LXVIII,333,(3) pp. and 1 folded engraved plate (showing his experimental apparatus). Light browning to margins of title-page, otherwise clean and with broad margins. A fine copy. First French edition of perhaps the most important work in plant physiology. It is in this work that Ingen-Housz for the first time expounds the ideas and experiments that lead to his discovery of Photosynthesis in plant life, and as such it is of fundamental importance in the economy of living things. "His Experiments upon vegetables was published in the autumn of 1779 and was at once recognized as a very important advance. In brief he showed, that oxygen evolution by plant is absolutely dependent on light and that it only occurs from those parts which are green.The proof that light and green tissues are both essential for oxygen production finally cleared up the apparent contradictions and variable results of earlier experiments. Priestly was "much pleased" with Ingen-Housz's experiments and pointed immediately to the salient facts that he had established." (A.G. Morton: History of Botanical Science. p. 332.).

"In the field of magnetism, Ingen-Housz experimented with artificial magnets, made according to the ideas of Gowin Knight, and devised methods of dampening the vibrations of magnetic needles. He also discovered the paramagnetism of platinum."(DSB).

(London, J. Nichols, 1779). 4to. Extract from "Philosophical Transactions, of the Royal Society of London." Vol. 69, Year 1779 - Part II. Pp. 376-418 and 1 folded engraved plate, showing apparatus (air pistols etc.). 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).
