Précis historique et expérimental des phénomènes électriques : depuis l'origine de cette découverte jusqu'à ce jour
This 1785 French treatise on electricity by Joseph Aignan Sigaud de La Fond, published in Paris, was written for natural philosophers and experimenters of its day. Its engraved plates show scientific apparatus drawn in fine black line on cream paper, with clear figure labels and cross-sections a designer could borrow for diagrammatic or vintage scientific graphics.
