lso 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

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

"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, sendin
