Clean and fine. <br/><br/><em>First appearance of the paper in which Wollaston announced his discovery of the metallic element Rhodium."Dr. Wollaston dissolved a portion of crude platinum in qgua regia and neutralized the excess acid with caustic soda. He then added salammoniac to precipitate the platinum as ammonium chloroplatinate and mercurous cyanide to precipitate the palladium as palladium cyanide. After filteringoff the precipitate he decomposed the excess mercurous cyanide inthe filtarate by adding hydrochloric acid and evaporating to dryness. When he washed the residue with alcohol everything dissolved except a beautiful dark red powder which proved to be a double chloride of sodium and a new metal which because of the rose color of its salts Dr. Wollaston named 'Rhodium'. He found that the sodium rhodium chloride could be easely reduced by heating it in a current of hydrogen and that after the sodium chloride had been washed out the rhodium remained as a metallic powder. he also succeeded in obtaining a rhodium button."Weeks: Discovery of the Elements. p. 104-05. </em> unknown

Davy was chemically preparing Potassium and Sodium through an electrical current and this made Gay-Lussac and Thénard envious of his success. They too decided to perform the same task but they had no battery at their disposal as Davy had so they had to form another way to chemically prepare the two elements. In 1808 they used a red-hot iron fused to potash the water-soluble form of a manufactured salt containing potassium to perform this task a method that Davy admitted had its advantageous qualities. Gay-Lussac and Thénard were successful in preparing Potassium and continued to make a full analysis of its chemical properties and began to use it for their own experiments.

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.

Internally clean and fine. <br/><br/><em>First printing of Faraday's famous letter to Gay-Lussac in which he claim to be the discoverer of electro-magnetic induction analysed the results of the Italian philosophers pointing out their errors and defending himself from what he regarded as imputations on his character. The style of this letter is unexceptionable for Faraday could not write otherwise than as a gentleman; but the letter shows that had he willed it he could have hit hard. The letter was later translated into English and published in "Philosophical Magazine" in 1840 under the title "On Magneto-electric Induction"."In 1831 seemingly out of nowhere came the discovery of electromagnetic induction and the beginning of the experimental researches in electricity which were to lead Faraday to the discovery of the laws of electrochemistry specific inductive capacity the Faraday effect and the foundations of classical field theory."
