J. A. H. Reimarus... neuere Bemerkungen vom Blitze; dessen Bahn, Wirkung, sichern und bequemen Ableitung: aus zuverlässigen Wahrnehmungen von Wetterschlägen dargelegt
A German treatise of 1794 by the Hamburg scholar Johann Albert Heinrich Reimarus, published by Carl Ernst Bohn, setting out observations on lightning, its path and effects, and how to conduct it safely to earth through lightning conductors. The pictures are engraved plates of conductor layouts, including a plan of a building with iron rods and insulated fixtures, a house elevation with tall pointed rods, a cross-section of chimney and conductor with a labelled ground pipe, and a close view of stepped masonry with a metal fixing. Designers could draw on their precise linework and lettered keys for technical diagrams.
