"My brother, in connection with Mr. Carpmael, one of the most distinguished patent agents in England, addressed a note to Mr. H. Cooper, the Attorney-General's secretary at the time, and the only official person besides Lord Campbell connected with the matter. The following is Mr. Cooper's reply:-- "'WILMINGTON SQUARE, May 23d, 1848. "'GENTLEMEN,--In answer to yours of the 20th inst., I beg to state that I have a distinct recollection of Professor Morse's application for a patent, strengthened by the fact of his not having paid the fees for the hearing, etc., and these being now owing. I understood at the time that the patent was stopped on the ground that a publication of the invention had been made, but I cannot procure Lord Campbell's certificate of that fact. "'I am, gentlemen "'Your obedient servant "'H. COOPER.' "I thus have obtained the evidence I desired in the most authentic form, but accompanied with as gross an insult as could well be conceived. On the receipt of this letter I immediately wrote to F.O.J. Smith, Esq., at Portland, who accompanied me to England, and at whose sole expense, according to agreement, all proceedings in taking out patents in Europe were to be borne, to know if this charge of the Attorney-General's secretary could possibly be true; not knowing but through some inadvertence on his (Mr. Smith's) part, this bill might have been overlooked. "Mr. Smith writes me in answer, sending me a copy _verbatim_ of the following receipt, which he holds and which speaks for itself:-- "'Mr. Morse to the Attorney-General, Dr. £ s. d. Hearing on a patent . . . . 3 10 0 Giving notice on the same . 1 1 0 ------ 4 11 0 Settled the 13th of August, 1838. "'(Signed) H. COOPER.' "This receipt is signed, as will be perceived, by the same individual, H. Cooper, who, nearly ten years after his acknowledgment of the money, has the impudence to charge me with leaving my fees unpaid. I now leave the public to make their own comments both on the character of the whole transaction in England, and on the character and motives of those in this country who have espoused Lord Campbell's course, making it an occasion to charge me with having _invented nothing_. "SAMUEL F.B. MORSE." I have, in these extracts from an account of his European experiences, written by Morse at a later date, given but a brief summary of certain events; it will now be necessary to record more in detail some of the happenings on that memorable trip.
