1834réf. 43654Paris Crochard 1834. No wrappers. In: "Annales de Chimie et de Physique" 2. Series Tome 56 Cahier 4 last issue of tome 56. Entire issue offered. Pp. 337-444. Peltier's paper: pp. 371-386. The text calls for a plate but not present here. First printing of the paper in which Peltier describes his discovery of the "Peltier-Effect" the thermo-electric cooling and heating of an electrical junction dependent on the direction of the current."Stimulated by the work of Nobili Peltier constructed a sensitive galvanometer to measure the conductivities of antimony and bismuth for small currents. Peltier's use of small samples of these nonductile materials was fortunate because the anomalous behavior of these materials led him to construct a thermoelectric thermoscope and to measure the temperature distribution along a series of thermocouple circuits. He discovered that a cooling effect can take place at one junction and an excessive heating at the other. He then confirmed this discovery by using an air thermometer in place of the thermoscope. Peltier did not pursue the effect he had discovered and its importence was not fully recognized until after the thermodynamic work of William Thomson twenty years later."DSB X p. 500.Wheeler Gift no 2684. - Ronald's Library p. 389. - Parkinson "Breakthroughs" 1834 P. unknown

1815réf. 45715London W. Bulmer and Co. 1815. 4to. No wrappers as extracted from "Philosophical Transactions" 1815 - Part II. Pp. 203-213 a. pp. 214-219. First appearance of two importent papers by davy. In the second paper offered he relates his discovery of chlorine dioxyd."By explosion over mercury he found that 2 vols. give from 2.7 to 2.9 of gas and this would probably be 3 vols. if no chlorine had been absorbed by the mercury. This gas contains 2 vols. of oxygen and the remainder chlorine hence the compound consists of 'two in volume of oxygen and one of chlorine condensed into the space of two volumes' ClO2. He found it to explode at about 100 deg. with more viollence than euchlorine."Partington III p. 57.Together with ROBERT PORRETT "Further analytical experiments relative to the constitution of the prussic; of the ferruretted chyazic and of the sulphuretted chyazic acids; and of their salts; together with the application of the atomic theory to the analysis of these bodies." pp. 220-230 a. 2 tables one folding. unknown

Balard's paper: pp. 634-641. First appearance of an importent paper in pharmacology as Balard here described his discovery of amyl nitrite and its preparation.Sir Thomas Lauder Brunton a Scottish physician later famously pioneered the use of amyl nitrite to treat angina pectoris. Brunton reasoned that the pain and discomfort of angina could be reduced by administering amyl nitrite to dilate the coronary arteries of patients thus improving blood flow to the heart muscle.Garrison & Morton No 1859. unknown

Grignard's paper: pp. 1322-24. One leaf repaired in upper margin affecting the text on verso but without loss of letters. Light browning poor paperquality. First apperance of an importent paper in which Grignard revealed the "Grignard Reagent" an important means of preparing organic compounds from smaller precursor molecules. For this work Grignard was awarded the Nobel Prize in Chemistry in 1912 jointly with fellow Frenchman Paul Sabatier."A large number of general synthetic methods had been developed by the end of the nineteenth century. However one of the most versatile and importent was first described as the new century opened. This was the Grignard synthesis." Leicester "A Source book in Chemistry 1900-1950" where this paper is translated "Some New Organometallic Compounds of Magnesium and Their Application to the Synthesis ofAlchohols and Hydrocarbons"."Grignard treated magnesium turnings in anhydrous ether with methyl iodide at room temperature preparing what came to be known as the Grignard reagent which could be used for reaction with a ketone or an aldehyde without first being isolated. On hydrolyzing with dilute acid the corresponding tertiary or secondary alcohol was produced in much better yield than Barbier had been able to obtain. Grignard’s discovery was reported in a short paper at a meeting of the Académie des Sciences in May 1900 the paper offered." DSB. unknown

Sobrero's paper: pp. 247-248. Clean and fine. First appearance of the paper in which Sobrero announced his discovery of nitroglycerin."When I think of all the victims killed during nitroglycerine explosions and the terrible havoc that has been wreaked which in all probability will continue to occur in the future I am almost ashamed to admit to be its discoverer." Sobrero"Nitroglycerin was synthesized by the chemist Ascagne Sobrero in the middle of the nineteenth century. When he tasted it as all good nineteenth century chemists did when they discovered a new compound it gave him what he called a migraine because of its vasodilatory effect which was later harnessed in the treatment of angina by William Murrell 1879 following the experience of a distinguished British clinician Lauder Brunton using amyl nitrite 1867 Later in the nineteenth century Alfred Nobel discovered how to stabilize nitroglycerin using kieselguhr diatomite clay; this led to highly successful industrial applications of dynamite and created the fortune that eventually funded the eponymous prizes. For medical purposes nitroglycerin was subsequently renamed glyceryl trinitrate to hide the fact that it was literally dynamite as well as metaphorically." unknown
