Provenance: Giancarlo Beltrame Library. ---- Wheeler-Gilft 450; Honeyman 256; Balbo 30. FIRST EDITION of Beccaria's short work on atmospheric electricity in fair weather. "This is the author's famous tract on the normal electricity of the atmosphere. Positive and negative electricity found, p. 4; observations on the electrical charges of clouds, p. 18; origin of atmospheric electricity, p. 32." (Wheeler-Gift). This treatise was published not before 1775, as can be seen from the print signatures of the three epistles (p. 27, 45, 53).
