The author,while studying for his medical degree, attended a course of public lectures given by Abbe Nollet, the tenor of which so inspired Siguad's subsequent interest in, and investigations of, experimental science at the College Louis-le-Grand. In 1760, Siguad succeeded the Abbe Nollet in his chair at Louis-le-Grand, where, along with anatomy & physiology, he continued "those courses in experimental physics that had been taught by his famous predecessor."
Siguad's "positive contributions to science were in the area of experimental technique. He is sometimes attributed with the invention of the glass insulator and the circular glass plate (to replace the glass globe) in electrical machines." This particular work written by him slanted more toward the "enlightened layman", rather than offering a rigorous technical treatise for his peers, nevertheless it does provide a significant historical summary on the subject of Electricity, as well as current thoughts of the 18th Century.
