The French State Legislature Council authorized an electrical line between Paris and the town of Marseille to be permanently installed to run a pantelegraph. England had an experimental line between the cities of London and Liverpool for a four-month period to test the operation of the device. Napoleon bought Caselli's pantelegraph as a public service and put into place for the transmission of images from Paris to Lyon. It was in place until the defeat of Sedan in 1870. Russian Tsar Alexander II put in an experimental service in place between his palaces in Saint Petersburg and Moscow between 1861 and 1865. In the first year of operation of the pantelegraph the system transmitted almost 5,000 faxes, with a peak of faxes being sent at the rate of 110 per hour. In spite of all this, the technology developed so slowly to make it fully reliable that it fell into oblivion. Caselli ultimately gave up on his invention and returned to Florence where he died. Although many of Caselli's patents, letters, and proofs of teleautographic transmission are nowadays kept at the municipal library of Siena, some can be found in the archives of the Museo Galileo in Florence.
