These papers show Davy's first ideas for an electric telegraph from his early sketches in 1836 of a frictional electric telegraph to one worked by electromagentism which he developed 1836-1839. His first patent was lodged in 1837 in opposition to Cooke and Wheatstone's first patent. The papers indicate his efforts to find a purchaser for the patent rights and to establish a company to develop the telegraph. He made agreements with several business men but none of these arrangements bore any fruit. He also negotiated with the railway companies and demonstrated the telegraph for them. The papers record the efforts of his father, Thomas Davy, and several others, to continue Davy's negotiations with the railway companies and the arrangements which were made to re-exhibit a working model of the telegraph. The papers also relate to the sale of the patent to the Electric Telegraph Company in 1847. Fahie's memoir on Davy is included in the papers.
