‎First appearance of Sauveur's last importent work on the theory of sound.""Later, in work presented in 1713 (the paper offered), Sauveur derived the frequency of a string theoretically. He treated the string, stretched horizontally and hanging in a curve because of the gravitational field, as a compound pendulum and he found the frequency of the swinging motion, assumed to have small amplitude. His results agrees with the modern one except for a factor of the quadratic root of 10/phi....... It was through Sauveur and the Paris Academy that ideas about harmonics became well known in the early eighteenth century. Sauveur's terminology, including ""harmonics"" and ""node"", was adopted and still is current."" (DSB XII, p. 128).‎

‎First printing of Savart's importent paper on the vibration of plates in which he greatly extended the investigations done by Chladni. The paper is an abstract, but was not published otherwise.Savart made experimental studies of many phenomena involving vibration. With Biot he showed that the magnetic field produced by the current in a long, straight wire is inversely proportional to the distance from the wire. In most of his vibrational studies Savart observed the nodal lines of vibrating surfaces and solids, and he thereby obtained information on vibrational modes and elastic properties.He also greatly extended Chladni's observations of the modes of plates: adding a dye to the sand, he made prints of the nodal patterns for brass plates in the shapes of circles, ellipses, and polygons. Savart was able to locate directly the nodes of a vibrating air column by lowering a light membrane covered with sand into a vertical pipe.‎

‎First printing of a pioneer paper on the acoustics of the violin and on the construction of the Trapezoidal Fiddle.""In his earliest work Savart gave the first explanation of the function of certain parts of the violin. To learn how vibrations are transmitted from the strings to the rest of the instrument, he induced vibrations in a free wood plate by passing a vibrating string over a bridge at its center" he also used Chladni’s sand-pattern technique to observe the resulting nodal lines. Savart showed that the bridge transmits the string’s vibrations that the plate can be made to vibrate at any frequency" and that the corresponding mode is a modification of an unforced mode. He demonstrated that the sound post also serves to transmit vibrations, and he explained that it therefore should not be placed under a nodal line. Thinking that symmetry and regularity would produce the best tone, Savart built a trapezoidal violin with rectangular sound holes. When the instrument was played before a committee that included Biot, the Composer Cherubini, and other members of the Academy of Sciences and the Académie des Beaux-Arts, its tone was judged as extremely clear and even, but somewhat subdued.""(DSB).The issue also contains Eilhard Mitscherlich' famous paper in the first French version ""Sur la Relation qui existe entre la forme cristalline et les proportions chimiques"", pp. 172-190.‎

‎First printing of Savary's importent paper, the phenomena investigated here helped Joseph Henry to discover sel-induction, and it was Savary who was the first to describe in this paper his hypothesis of the oscillatory nature of the discharge of a Leyden jar connected to an inductor. In his Mémoire, he documented the experiments which helped lead to his conclusion of the oscillatory discharge of the Leyden jar, which Joseph Henry expanded upon fifteen years later in America while working on his experiments in induction.""Savary inferred that a charged Leyden jar would discharge in a damped oscillatory manner. This inference was based on observations of magnetization of short thin steel needles. Here needles were placed at varying distances near (and perpendicular) to a 2-meter-long wire loop used to discharge the Leyden jar. Magnetization of the needles would reverse direction (up to three times) as a function of distance from the wire in the loop. (Needles were placed close to the wire starting from a fraction of a mm to about 1 cm away.) Joseph Henry was stimulated by Savary's observation. Henry repeated Savary's work starting in 1835 and then extended it to magnetizing steel needles in a secondary circuit. Henry published his findings in 1842. Henry placed a steel needle in a spiral in a secondary circuit and removed the secondary circuit to a distance of 30 feet. The magnetizing of a steel needle at this distance is evidence of high frequency transmission and detection. We are working to determine the general range of frequencies of oscillation in Henry's study, but it appears to be near 6 MHz. At 6 MHz the wavelength of the radiation is 50 meters (150 feet), so Henry's observation of magnetization at a distance of 30 feet corresponds to the near field. This remote magnetization is evidence of high-frequency induction rather than radio transmission as is sometimes suggested.""

‎First printing of this seminal paper in which the push-button telephone is first described. Push-button telephony was considered a revolution within telecommunication. It replaced rotary dial telephones that had been in use since 1891 and the technique behind the touch-tone format is today used for all cell phones.The first prototypes were invented in 1941 by the Bell System, these were, however, never fully functional and therefore not brought to the commercial market. The research was shelved during WWII and was not prioritized until later, after the transistor had been developed and tones could be produced with electronic oscillators in the late 1950ies. The first push-button telephone reached the commercial market in 1963, though in the mid 1970ies the majority of phone users still had rotary phones.The issue contains the following papers:1.
