Soft cover. Zustand: Very Good. Sylvanus P. Thompson. "Sound-Mills" in Nature, February 14, 1884, pp 363-364, in the weekly issue of pp 353-376, and with several text illustrations. Nice copy, the weekly issue removed from a larger bound volume. Very Good. __+__The opening paragraph of the Thompson paper describes the instrument… in general, and introduces the work of Dvorak: "After the notable researches of [Sir William] Crookes on radiation, which culminated in the discovery of the radiometer, or lightmill, it was a natural transition of thought which suggested to several minds almost simultaneously the possibility of devising an apparatus which should rotate under the influence of sound waves as does the radiometer under the influence of the rays of light and heat. Such instruments were indeed devised independently about six years ago by Lord Rayleigh, by Prof Alfred M. Mayer of Hoboken, by Mr Edison, the well-known inventor, by Prof Mach of Prague, by Dr A. Haberditzel of Vienna, and by Prof Dvorak of the University of Agram (in Croatia). These researches, though of great scientific interest, have been somewhat overlooked in the rush of scientific inventions during the intervening years. During the course of the past year, however, Dvorak has given to the world, in the pages of the Zeitschrift der Instrumentenkunde (vol. iii, Heft 4), a detailed account of his experiments, together with figures of various piece of apparatus hitherto undescribed. We propose to give a resume of the principal points of Dvorak's researches."__+__ Much of the rest of the paper describes four different Dvorak instruments.

Soft cover. Zustand: Very Good. [HERTZ-WAVE MODEL] Thompson, Sylvanus P. "A Hertz-Wave Model", in Nature, August 12, 1897, pp 342-343. Thompson (1851-1911) constructed a two-metre-long wooden mechanical wave-motion model for a demonstration before the Physical Society of London, "illustrat(ing) the propagation of a transverse wa…ve". Nice copy, with the original front wrapper, removed from a larger bound volume. +++ "At one end is the oscillator a heavy mass of brass hung by two strong cords from arms which project parallel to the longer dimension of the frame. This mass which for the sake of analogy is quite unnecessarily shaped to imitate an orthodox electric oscillator can therefore be set swinging in a transverse direction by a suitable impulse given by hand. At the other end of the frame is the "resonator" a circle of brass wire hung by a tri filar suspension Oscillator and resonator must be adjusted by shortening or lengthening the cords so as to have identical periods of oscillation. The real problem in the construction of the apparatus was to find a mechanical means of transmitting the the energy of the oscillator in visible waves to the resonator. The means finally adopted was a series of inter connected pendulums on a plan somewhat similar to one suggested in 1877 by Prof Osborne Reynolds. Instead of using springs however the requisite inter connection is obtained by simply suspending the leaden bullets which act as pendulum bobs by V suspensions ,which overlap and which as shown in the cut are tied together at a point about 4 centimetres above each of the balls. No ball can be laterally displaced without tending to drag its neighbour also so that a shearing stress is transmitted along the line of balls As Reynolds showed twenty years ago the velocity of propagation of the wave front differs from that of the group of waves owing to the continual dying away of the amplitude of the advancing waves. This effect due to the inertia of the medium is of course equivalent to the presence of dispersion in the medium waves of different frequencies being propagated with slightly different velocities. So far, therefore, as I Prof Fitzgerald remarked when the model was exhibited it illustrates the propagation of the wave in a refracting medium rather than in the ether of space. The waves in the model travel quite slowly and there is a fascination in watching their progress along the row of balls until they arrive at the resonator and set it into responsive vibration. There is of course no attempt made here to represent the magnetic part of the electromagnetic wave at right angles to the electrostatic part the mechanical displacements in the model corresponding to the electrostatic displacements of the Hertzian wave. A row of interconnected pendulums such as this affords a means of illustrating many points in physics For many purposes the elaborate system of suspension by strings may be replaced by a continuous fabric. Thus for example a piece of netting hung on hooks from a horizontal rail and ending below in a short fringe with leaden beads on the fringe tips will also serve to illustrate the propagation of a transverse wave. The structure adopted absolutely refuses to transmit longitudinal disturbances there being no compressional elasticity between the balls to propagate a longitudinal wave."--(from the article).

Original burgundy cloth, boards blocked in blind, spine lettered direct in gilt. Binding dampmarked, spine gilding rubbed, endpapers sometime renewed. Modern bookplate to pastedown, clipping from bookseller'…s catalogue tipped in to flyleaf, folded a4 printout on Reis' invention loosely inserted. The first edition of this biography of German scientist Johann Philipp Reis (1834-1874), inventor of a crude telephonic device. Although it was able to transmit sounds by electrical impulses in a wire, intelligible speech was beyond its capabilities. The battle for the title of 'inventor of the telephone' is a crowded field with many claimants, and experimenters both before and after Reis, although he is credited with inventing the word 'telephon', which was later anglicised as telephone.
