Villard's papers: pp. 1010-1012 a. 1178-1182 textillustrations. <br/><br/><em>First apperance of Villard's two papers in which he announced and described the discovery of a new type of radiation more powerfull and penetrating than alpha-and beta rays. The new type of rays was named by Rutherford as gammarays."His Villardexperiments in radioactivity led to the unexpected discovery of gamma rays in 1900. Villard recognized them as being different from x rays because the gamma rays had a much greater penetrating depth. He had discovered they were emitted from radioactive substances and were not affected by electric or magnetic fields. These came to be called gamma rays by another scientist Ernest Rutherford. It wasn't until 1914 that Rutherford showed that they were a form of electromagnetic EM like light only with a much shorter wavelength than x rays. Now we know that gamma rays are a form of EM radiation similar to x rays. Gamma rays tend to have a higher energy and a shorter wavelength than x rays do. However the dividing line between these two forms of radiation is not clearly defined. Scientists typically apply the term gamma ray to EM radiation with energies above several hundred thousand electron volts."

Two days later he made a more remarkable discovery. It had occurred to him that perhaps thetransformation of amygdalin could be effected by the albumin in the almonds in a manner similar to the action of yeast in sugar.Wöhler suspected that the decomposition was an example of what Berzelius had recently defined as catalysis. Liebig and Wöhler then divided up the detailed examination of the properties and composition of amygdalin. They precipitated from the emulsion of almonds a substance which when dissolved retain its action. They named the active substance "emulsion".

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
