Description
This illustrated pamphlet, written in German, publishes testimonials to the value of the coordinatograph, an instrument for plotting graphical coordinates (e.g. x- and y-coordinates) mechanically. Coradi first sold a form of the instrument in 1887. The pamphlet, published in 1913, prints letters from nine users in locations ranging from Russia to Switzerland to Egypt to New York. For further documentation on the coordinatograph, see 1977.0112.03 and 1977.0112.05.
The documentation was received with a Coradi rolling sphere planimeter with number 1977.0112.01.
