"Under these circumstances I left Paris on the 13th of March, 1839, and arrived in London on the 15th of the same month. The next day I sent my card to the Earl of Lincoln and my letter and card to the Marquis of Northampton, and in two or three days received a visit from both. By Earl Lincoln I was at once invited to send my Telegraph to his house in Park Lane, and on the 19th of March I exhibited its operation to members of both Houses of Parliament, of the Royal Society, and the Lords of the Admiralty, invited to meet me by the Earl of Lincoln. From the circumstances mentioned my time in London was necessarily short, my passage having been secured in the Great Western to sail on the 23d of March. Although solicited to remain a while in London, both by the Earl of Lincoln and the Honorable Henry Drummond, with a view to obtaining a special Act of Parliament for a patent, I was compelled by the circumstances of the case to defer till some more favorable opportunity, on my expected return to England, any attempt of the kind. The Emperor of Russia, however, refused to ratify the contract made with me by the Counselor of State, and my design of returning to Europe was frustrated, and I have not to this hour [April 2, 1847] had the means to prosecute this enterprise to a result in England. All my exertions were needed to establish my telegraphic system in my own country. "Time has shown conclusively the essential difference of my telegraphic system from those of my opponents; time has also shown that my system _was not published_ in England, as alleged by the Attorney-General, for, to this day, no work in England has published anything that does not show that, as yet, it is perfectly misunderstood.... "The refusal to grant me a patent was, at that period, very disastrous. It was especially discouraging to have made a long voyage across the Atlantic in vain, incurring great expenditure and loss of time, which in their consequences also produced years of delay in the prosecution of my enterprise in the United States." The long statement, from which I have taken the above extracts, was written, as I have noted, on April 2, 1847, but the following interesting addition was made to it on December 11, 1848:-- "At the time of preparing this statement I lacked one item of evidence, which it was desirable to have aside from my own assertion, viz., evidence that the refusal of the Attorney-General was on the ground '_that a publication of the invention had been made_.' I deemed it advisable rather to suffer from the delay and endure the taunts, which my unscrupulous opponents have not been slow to lavish upon me in consequence, if I could but obtain this evidence in proper shape. I accordingly wrote to my brother, then in London, to procure, if possible, from Lord Campbell or his secretary an acknowledgment of the ground on which he refused my application for a patent in 1838, since no public report or record in such cases is made.
