A machine for the mechanical performance of mathematical operations, for the most part invented by Charles Babbage and G. and E. Scheutz. It computes logarithmic and other mathematical tables of a high degree of intricacy, imprinting the results on a leaden plate, from which a stereotype plate is then directly made.
