  • PRESENTATION COPY "FROM THE AUTHOR" OF THE FIRST COMPLETE EDITION -"THE MOST IMPORTANT SCIENTIFIC BOOK OF EIGHTEENTH-CENTURY AMERICA" (PMM).

    First published in 1751-53, Franklin's ground-breaking work on electricity proved the existence of positive and negative charges as well as the concepts of insulators and conductors. It included his famous Leyden jar, kite and key experiments, and led to the invention of the lightning rod. The present fourth edition was updated by the author to include full notes on all of his experiments, along with correspondence between Peter Collinson, Franklin and other collaborators.

    Provenance: UK private collection.
