1.13 Eidograph 1.14 EIDOGRAPH The eidograph is also used for the same
purposes as the pentagraph. The pentagraph requires four supports on the paper
and has numerous joints; its action is apt to be unsteady. In contrast, eidograph
has ...

"The Eidograph was invented by Professor Willis in 1821. It is a most ingenious
and exact instrument, for many purposes superior to the pantograph, within the
range of its working powers, which however, may be considered to be limited to ...

... the paper, to diminish the friction. Another instrument for the same purpose has
been invented by Professor Wallace of Edinburgh, called the Eidograph ; it is
more elaborate and expensive, but far superior to the Pentagraph in the precision
