"I feel it to be my duty to write to you upon another point regarding
your report, upon which I know that you are sensitive, but, as I think
you will see that my motives are good, and that I sincerely express them,
I believe you will not be offended with me although my views and opinions
may not coincide exactly with yours. I allude to the mention which you
make of some of the eminent physicists who have contributed by their
discoveries and experiments to our knowledge of the phenomena of
electro-magnetism.

"On page 9 of the manuscript you observe: 'The application of the
electro-magnet, the invention of Arago and Sturgeon (first combined and
employed by Morse in the construction of the generic telegraph) to the
purposes also of the semaphore, etc.'

"Frankly, I am pained not to see the name of Henry there associated with
those of Arago and Sturgeon, for it is known and generally conceded among
men of science that his researches and experiments and the results which
he reached were of radical importance and value, and that they deservedly
rank with those of Ampere, Arago and Sturgeon.

"I am aware that, by some unfortunate combination of circumstances, the
personal relations of yourself and Professor Henry are not pleasant. I
deplore this, and it would be an intense satisfaction to me if I could be
the humble means of bringing about a harmonious and honorable adjustment
of the differences which separate you. I write this without conference
with Professor Henry or his friends. I do it impartially, first, in the
line of my duty as editor (but not now officially); second, as a lover of
science; third, with a patriotic desire to secure as much as justly can
be for the scientific reputation of the country; and fourth, with a
desire to promote harmony between all who are concerned in increasing and
disseminating knowledge, and particularly between such sincere lovers of
truth and justice as I believe both yourself and Professor Henry to be.

"I do not find that Professor Henry anywhere makes a claim which trenches
upon your claim of first using the electro-magnet for writing or printing
at a distance--the telegraph as distinguished from the semaphore. This he
cannot claim, for he acknowledges it to be yours. You, on the other hand,
do not claim the semaphoric use of electricity. I therefore do not see
any obstacle to an honorable adjustment of the differences which separate
you, and which, perhaps, m
