Janssen's paper pp. 367-376. First printing of the paper in which Janssen announced the discovery of a new element. On August 18 1868 Janssen managed to do just that. He became the first person to observe helium an element never before seen on Earth in the solar spectrum. At the time though Janssen didn’t know what he’d seen"just that it was something new""Helium the second most abundant element in the universe was discovered on the sun before it was found on the earth. Pierre-Jules-César Janssen a French astronomer noticed a yellow line in the sun's spectrum while studying a total solar eclipse in 1868. Sir Norman Lockyer an English astronomer realized that this line with a wavelength of 587.49 nanometers could not be produced by any element known at the time. It was hypothesized that a new element on the sun was responsible for this mysterious yellow emission. This unknown element was named helium by Lockyer." unknown

Entire issues offered. Pelletier & Caventou's papers: pp. 323-324 tome 8 and pp. 142-176 tome 10. A few scattered brownspots. First printing of these classic papers in chemistry in which the authors announced their discovery of Strychnine. This was the first alkali of vegetable origin to be discovered after morphine. This discovery and their discovery of chlorophyll brought them international fame. The first small paper contains the announcement of the discovery and the second long memoir contains the elaborate exposition of the discovery."Strychnine was only the second alkaloid to be extracted the first was morphine. Pelletier and Caventou wanted to name their new alkaloid vauqueline after Nicolas Vauquelin one of their associates who had refined the technique of ether extraction for use in isolating alkaloids. However the officers of the Académe des Sciences in Paris rejected the idea on the grounds that a respected scientist’s name should not be paired with a deadly poison. In addition to strychnine the pair isolated other important compounds from plants including caffeine chlorophyll and the anti-malaria drug quinine. Paul L.

First printing of Ritter's announcement of his discovery of ultraviolet light in a halfpage letter addressed to Gilbert's Annalen. With that discovery it became clear that visible light represents no more than a fraction of a continous spectrum.A year earlier in 1800 William Herschel discovered infrared light. This was the first time that a form of light beyond visible light had been detected. After hearing about Herschel's discovery of an invisible form of light beyond the red portion of the spectrum Ritter decided to conduct experiments to determine if invisible light existed beyond the violet end of the spectrum as well. He had heard that blue light caused a greater reaction in silver chloride than red light did. Ritter decided to measure the rate at which silver chloride reacted to the different colors of light. He directed sunlight through a glass prism to create a spectrum. He then placed silver chloride in each color of the spectrum and found that it showed little change in the red part of the spectrum but darkened toward the violet end of the spectrum. Johann Ritter then decided to place silver chloride in the area just beyond the violet end of the spectrum in a region where no sunlight was visible. To his amazement this region showed the most intense reaction of all. This showed for the first time that an invisible form of light existed beyond the violet end of the visible spectrum. This new type of light which Ritter called Chemical Rays later became known as ultraviolet light or ultraviolet radiation the word ultra means beyond. - Parkinson Breakthroughs: 1801 P. unknown

1866xxii, 638, 6 (ads) pages. Fold-out map. Occasional black and white illustrations. "It has been my object in this work to give as clear an account as I was able of tracts of country previously unexplored, with their river systems, natural productions, and capabilities; and to bring before my countrymen, and all others interested in the cause of humanity, the misery entailed by the slave-trade in its inland phases - a subject on which I and my companions are the first who have had any opportunities of forming a judgement." - from Preface. "There must be something in the appearance of white men frightfully repulsive to the unsophisticated natives of Africa; for, on entering villages previously unvisited by Europeans, if we met a child... he would take to his heels in an agony of terror, such as we might feel if we met a live Egyptian mummy at the door of the British Museum." - from page 199.

First appearance of Raoult's two importent papers in which described a method for finding the molecular weight of an organic compound by the determination of the lowering of the freezing point of water that resulted from dissolving that compound in water and the law governing the relation between solutes and vapor pressure."Then in 1882 F.-M. Raoult published his results on the effects of nondissociating organic solutes from which he deduced a general law controlling the lowering of freezing points the first paper offered. Four years later he extended this work to show the effect of solutes on vapor pressure the second paper offered. Having established the effect of nondissociating compounds he was in position to show that salts produced an eeffect which though anomalous could nevertheless be explained by the supposition that a dissolved molecule broke up into other molecules. This work was of great value in supplying a new method for determining molecular weights since the depression of freezing point and vapor pressure as well a the related rise in boiling point later discovered are proportional to the moleculat concentrations ofthe solutions; it was of equal value in supporting the ideas of van't Hoff on osmotic pressure. With the announcement of the dissociation theory of Arrhenius the anomalies were explained and the full significance of the generalizations of Raoult was recognized. Raoult published the formulations of his laws in the "Comptes Rendus" for 1882 and 1887 the papers offered" Leicester a. Klickstein "A Source Book in Chemistry" pp. 471 ff. unknown

The entire issue offered. Henry's paper: pp. 282-312. First German version of Henry's description of his discovery of self-induction. He missed the credit for the discovery of induction to Faraday but he had done the key experiment ahead of Faraday but Faraday was the first to publish. But he is credited for the discovery of self-induction 1832 and Faraday discovered it independently two years later 1834."In Henry's paper however he explained thet the electric current in a coil can induce another current not only in another coil but in itself. The actual current observed in the coil is then the combination of the original current and the induced current. This is called self induction."Isac Asimov.The issue contains further notable papers Michael Faraday's "Vierzehnte Reihe von Experimental-Untersuchungen über Elektricität" § 2o-22. Nos 1667-1748. Pp. 249-281. First German version. In this paper FARADAYamplifies his theory of electrostatic induction by making further use of the analogy with the induction of magnetism. Whittaker describes the paper as having "THE FUNDAMENTAL EQUATION OF ELECTROSTATICS" as modified in order to take into account the effect of the specific inductive capacity."Whittaker I pp.187-89. unknown

Describes the explorations in the interior of Africa of Daniel Houghton 1740 - 1791 and Mungo Park 1771 - 1806. Daniel Houghton was sent by the African Association the Association for Promoting the Discovery of the Interior Parts of Africa; his instructions were to sail to the mouth of the Gambia navigate the river to the Barra Kunda falls and then to travel overland to the Hausa lands to the east. He was one of the first European explorers in the interior of Africa but after a successful visit in Bambouk territory he disappeared somewhere on his journey to Timbuctoo his last despatch being in July 1791. Mungo Park was then sent by the African Association and travelled more extensively in West Africa. He published the book "Travels in the interior districts of Africa" in 1799 i.e. this book precedes Park's publication. Uncommon. 1st Edition. Leather. Chez Tavernier hardcover
