Korn's paper: pp. 892-895. And one diagram in the text. Paperquality rather poor a bit fragile. In this paper Korn gives a technical decription of his invention of his telephotographic machine later the fax-machineIn 1902 Arthur Korn 1870-1945 in Germany invented telephotography a means for transmitting still photographs by means of electrical wires. In 1907 Korn sent the first inter-city fax when he transmitted a photograph from Munich to Berlin. By 1906 his equipment was being put into regular service for transmission of newspaper photographs between Munich and berlin via telegraph circuits.

Babbage's paper: pp. 557-560. Some faint mostly marginal brownspots. First printing of this importent paper being babbage's report on the Scheutz differnce calculator explaining its functions by way of his own notations."Babbage's report on the differnce engine built by the Swedish printer Georg Scheuts 1785-1873 and his son Edvard 1821-81 based on Babbage's own designs. In 1854 the Scheutzes took their engine no. 2 to England in the hopes of marketing it. There they were introduced to Babbage who received them with great friendliness and showed a lively interest in their work. Babbage devoted two whole days to investigating Scheutz' engine for which he had much praise especially for the way they had succeeded in building it with the funds at their disposals. As part of his effort to promote the Scheutz Engine Babbage gave a talk on it before the Academie des Sciences illustrated with drawings by his son henry in which Babbage's system of mechanical notation was used to describe the machines construction and functions. This talk was published the paper offered without illustrations in the Academie 'Comptes rendus'. Hook & Norman "Origins of Cyberspace" No. 73. unknown

The paper: pp. 330-339. First apperance of this detailled report and examination by the French mathematiciens Mathieu Chasles and Delaunay of the calculating machine invented by Martin Wiberg as an improvement on the Scheutz machine. The machine could produce tables of logarithms."Wiberg modified the Scheutz difference engine making it smaller and lighter and used it to calculate a series of interest tables published in 1860. Efter improving the print mechanism of his machine Wiberg presented it to the Academy of Sciences in Paris which voted in 1863 to "accorder son approbation à cette belle et ingénieuse machine" the paper offered. Wiberg later used the machine to produce a set of tables of seven-place logarithms of the numbers from 1 to 1000000 together with logarithms of trigonometric functions published in 1876 under the title 'Tables de logarithmes calculées et imprimées au moyen de la machine à calculer sw M. Wiberg'. Hook & Norman "Origins of Cyberspace" No. 82. unknown

First appearance of an importent paper in the history of calculating machines."In his first year at Liverpool he published a paper on 'The theory of continuous calculating machines and of a mechanism of this class on a new principle' in the prestigious Philosophical Transactions of the Royal Society. This work investigated how to advance the design of integrator mechanisms and fit them for tasks more complex than mere numerical calculating machines and was extremely important in the development of analogue computing."Jane Carruthers unknown
