This is an advertising brochure created by the firm of
Maurel and Jayet for their multiplication machine. The
first part consists of a reprint of a report recommending
the machine to the French Academy. This is followed
by reprints of glowing testimonials from the press and
private citizens.
The Arithmaurel was designed especially to do
multiplication. As the drawing on the front cover
indicates, a multiplicand of up to eight digits is set on
the uppermost bars extending from the front of the
machine. Four lower keys (one for units and others for
tens, hundreds and thousands) are then turned to enter
the multiplier. Answers may be read from the lower set
of result dials while an upper set keeps a running total of
the series of multiplications.
The machine was not popular, and today only a few
examples survive in the collections of the Conservatoire
des Arts et Métiers and in private hands.

Maxwell was born in Edinburgh and was educated at
Edinburgh Academy before going on to Cambridge.
His remarkable mathematical and scientific aptitude
was evident even as a boy. At the age of fourteen, he
read his first paper, On the description of oval curves
… to the Royal Society of Edinburgh. He is, of course,
best known for his work on electricity, magnetism and
the electromagnetic theory of light. He was, however,
interested in many other branches of physics and
mathematics. Maxwell taught in Cambridge and Aberdeen
