Boisbaudran's papers: pp. 493-495 a. pp. 1100-1105. <br/><br/><em>First printing of the paper in which Boisbaudran announced his discovery of Gallium together with the first printing of the paper in which he by a series of experiments proved that Gallium the metal that he had discovered amd named in honour of France is a true element. A larger paper on the discovery was published in 1877 in "Annales de Chimie et Physique". In 1879 Bausbaudran was awarded the Davy Medal for his discovery of Gallium. "In 1875 Boisbaudran spectroscopically discovered a new element gallium which he found in zinc blende from a mine in Hautes-Pyrénées. Continuing his work in Wurtz’s laboratory in Paris he was a able to obtain the free metal by electrolysis of a solution of the hydroxide in potassium hydroxide. Gallium Boisbaudran realized was the "eka-aluminum" predicted by Mendeleev and was the first of Mendeleev’s predicted elements to be isolated. Boisbaudran’s finding thus provided valuable evidence for the validity of Mendeleev’s periodic classification of the elements."DSB."Lecoq de Boisbaudran announced his discovery by spectroscopic analysis of the new element gallium. Mendeleev had first predicted its existence and had named it eka-aluminium. The discovery was made in the author's private laboratory in a specimen of zinc blende from the Pierrefitte mine in the Angelès Valley in the Hautes Pyrénées. He describes how on the evening of 27 August 1875 he detected the existence of this new element which he named "gallium" in honor of France Gallia. A month later he "performed in Wurtz's laboratory in Paris.a series of experiments to prove that gallium.is a true element"Weeks. he discusses how he eventually isloated small amounts of pure metallic gallium and determined its physical and chemical properties. The paper the paper offered first describes gallium compounds e.g. ammonium gallium alum chloride oxide and sulphate."Roy G. Neville II p. 29. </em> unknown

Some scattered brownspots. <br/><br/><em>First German translation of Davy's announcement the announcement on 1 page of his discovery of the unusual anaesthetic effects of nitrous oxide which on being inhaled gave rise to a giddy intoxicated feeling. On announcing his discovery he says that he will publish a paper discribing the experiments with the gas later. This is the paper offered here also in the first German version. Both the announcement and the paper were issued in the "Annalen" the same year as they appeared in Nicholson's Journal.The gas was first synthesized by English natural philosopher and chemist Joseph Priestley in 1772 who called it phlogisticated nitrous air."Following Priestley's discovery Humphry Davy of the Pneumatic Institute in Bristol England experimented with the physiological properties of the gas such as its effects upon respiration. He even administered the gas to visitors to the institute and after watching the amusing effects on people who inhaled it coined the term 'laughing gas'! Davy even noted the anaesthetic effects of the gas: "As nitrous oxide in its extensive operation appears capable of destroying physical pain it may probably be used with advantage during surgical operations in which no great effusion of blood takes place".Wikipedia."Davy discovered the anaesthetic properties of nitrous oxide and suggested its use during surgiical operations a suggestion which was not turned to useful account until 1844."Garrison & Morton 5646 not mentioning the announcing of its discovery in 1799. </em> unknown

Pp. 387-528. Ritter's announcement p. 525. With titlepage to volume 7. Clean and fine. Titlepage a bit shavedin inner margin. <br/><br/><em>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. </em> unknown

Two years later he named them anaerobic or zymics contrasting to aerobic which only lived in the presence of free oxygen."In 1861 he turned his attention to the butyric fermentation and made another importent discovery viz. that this fermentation proceeds in the absence of oxygen. In the fermented material he found cylindrical rods which he showed were the cause of the fermentation. Following the nomenclature and ideas of the time he regarded them as animal in character and named them Vibrio." Bullock "The History of Bacteriology" p. 61. </em> unknown

A9780309438841Paperback / softback. New. The field of endeavors known as aEUROoeregulatory scienceaEURO has grown out of the need to link and integrate knowledge within and among basic science research clinical research clinical medicine and other specific scientific disciplines whose focus aggregation and ultimate implementation could inform biomedical product development and regulatory decision making. Substantial efforts have been devoted to defining regulatory science and communicating its value and role across the scientific and regulatory ecosystems. Investments are also being made in technology infrastructure regulatory systems and workforce development to support and advance this burgeoning discipline. In October 2015 the National Academies of Sciences Engineering and Medicine held a public workshop to facilitate dialogue among stakeholders about the current state and scope of regulatory science opportunities to address barriers to the disciplineaEURO TMs success and avenues for fostering collaboration across sectors. Participants explored key needs for strengthening the discipline of regulatory science including considering what are the core components of regulatory science infrastructure to foster innovation in medical product development. This report summarizes the presentations and discussions from the workshop. paperback
