Brugmans, Tentamina philosophica de materia magnetica (1765), title page

JAN 01 1765

The title page of Brugmans's 1765 treatise on magnetic matter and its action on iron and the magnet. It is his major published magnetic work and sets the stage for the bismuth-repulsion observation he recorded in 1778. A genuine 18th-century printed page, so it carries the right typographic period for the opening scene.
