Experiments and Observations on Electricity is a treatise by Benjamin Franklin based on letters that he wrote to Peter Collinson, who communicated Franklin's ideas to the Royal Society.[1][2] The letters were published as a book in England in 1751, and over the following years the book was reissued in four more editions containing additional material, the last in 1774.[3] Science historian I. Bernard Cohen crafted an edition with historical commentary that was published in 1941.[1][3][4][5]
