Dear Sir

according to the Contents of your letter, I have sent the two volumes of
your work with one of the three copies of the prospectus printed on one
Sheet of paper in 4°, to the Society of Harl sciences of sciences of Haerlem, requesting
to look upon it only as a rough scets of what the author intends to make
of it. I Wrote to Mr Van Marum Director of this society, that it will give
satisfaction to the author, if some ingenious men will communicate him their
refexions. I allso inform him that the plan will probably soon be executed
in Irland.

to proove you, that I have not neglected y to fulfill your desires of possessing
a copy of the description of the new electric machine, I have recieved it
by the last male and send it to you. it prooves to be of an immense
force for reason of the perfect insulation of the prime Conductor. it
has the great advantage of granting from the same conductor negative or
positive electricity ad libitum. I hope it will amuse you so as to order
one to be made, the first in Great Brittain

I am respectfully
yours. I Ingen House
