Bion had an instrumentation workshop in Paris.
He seems to have made globes, sundials, mathematical instruments, and mechanical machines with equal accuracy.
In the "Traité de la construction.." he gives a fairly complete list of instruments normally constructed during the first quarter of the eighteenth century.
His treatise was more for the user and the amateur than for the manufacturer. (DSB)
