An artificial Spider, which moves by Electricity.

Take a bit of burnt cork, as big as a pea; give it the shape of a spider; make its legs with threads of hemp; put a grain of lead in the cork to give it some weight; then hang this artificial spider by a bit of grey sewing silk (that is not twisted) between two bodies, the one electrified and the other not; or between two bodies endowed with different electricities: it will go and come between these two bodies, and the movement of the legs will be seen as plain as if it were a living spider.

This artificial spider, if well made, will astonish those who see it move so naturally.
