A stamp to verso of frontispiece Library of Congress duplicate stamp. <br/><br/><em>First printing of this importent paper the first to describe in detail how the phenomena of Self-Induction was discovered. Henry discovered the induction phenomena - how an electric current in one coil may set up a current in the other through the development of the magnetic field - independently of Faraday but Faraday was first to publish on electromagnetic induction. Henry's experiments with induction led him to his importent discovery of SELF-INDUCTION which is the phenomenon in which a change in electric current in a coil produces an induced emf in the coil itself. This phenomenon was also discovered inependently by Faraday but this time Henry had published first. The basic unit of inductance was to be called "the Henry". Relevant to the controversy between Faraday and Henry is the following statement by A D Bache Secretary of the American Philosophical Society introducing an abstract of Henry in J Franklyn Inst. 1835 pp. 169-70 H. Norman 1053 and the paper offerd: "A memoir on this subject has been since submitted to the Society containing an extension of the subject the primary fact in relation to which was observed by Professor Henry as early as 1832 and announced by him in the American Journal of Science. Mr. Faraday having recently entered upon a similar train of observations the immediate publication of the accompanying is important that the prior claims of our fellow countryman may not be overlooked."Spark Museum.Magee "Source Book in Physics" p. 515. </em> hardcover

"Arago . made several important contributions to electromagnetism on his own. On 20 September 1820 he announced the discovery of the temporary magnetization of soft iron by an electric current which suggested to Ampère a theory about the nature of magnetic "currents" and provided the technological key to the electric telegraph. Ampère calculated that the magnetic power could be multiplied by twisting the current-carrying wire into a helix and with Arago he carried out the first experiments on primitive solenoids. In his historical articles Arago was always careful to credit Ampère with the major share of this discovery which ultimately depended upon Ampère’s mathematical theory."DSB.Arago formed a close freinship with Fresnelwhose views on the nature of light he ardently supported. He assisted Fresnel in some of his most importent work and made original discoveries in the same field.Magie "A Source Book in Physics" p. 443 ff. </em> unknown

The potential varied directly with the pressure and they named the phenomenon Piezoelectricity meaning "to press" Greek. Crystals with piezoelectric properties form an essential portion of sound-electronics devices such as microphones and record-players."The applications of piezoelectric crystals are innumerable; one of the most important is their use in frequency stabilization of oscillating electromagnetic cirasciots for radio broadcasting stations. They are used in most piezometers for measuring with great precision either very strong pressure variations such as those of a cannon at the moment of firing or very weak ones such as artery pulsations. These applications have led to the creation of a new industry the manufacture of large "mono" such as quartz obtained hydrothermally around 500°C. under high water pressures or crystals such as Rochelle salt obtained from aqueous solutions. These two substances were mentioned in the Curie brothers’ report announcing the discovery of piezoelectricity."

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
