‎Anmerkungen über die nöthige Achtsamkeit bei Erforschung der Gewitter-Electricität. - [RARE EARLY WORK ON LIGHTNING AND ELECTRICAL STORMS]‎

‎Hannover, Adolph Wecken, 1764. 4to. In contemporary marbled paper covered boards. Spine missing and boards partly detached. Internally nice and clean. (2), 57 pp. + 2 folded plates. ‎

‎The exceedingly rare first edition of Hartmann’s work on lightning and electrical storms, in which he discusses the significance of researching storm electricity, noting the broader value of understanding electrical and magnetic forces. He points out that even if immediate practical applications are not apparent it could be possible to harness the energy in the future. Hartmann's research on electricity was a continuation of the scientific revolution in electrical studies that Benjamin Franklin had worked on the previous decade. We have only been able to trace one copy in the trade. Not in Poggendorff.‎
