I received your Note <1> this Morning, and beg leave to say that the way I have wound the the [sic] Iron is the best of several that I have tried I have tested the magnetic power as far as 6, Cwt its [sic] construction being different to [sic] any I have yet made I have not an Apparatus to test it farther but am satisfied it will sustain Much more To try its attractive power, with one cell and then with two with intensity arrangement I applyd [sic] a piece of Iron 4 Inches long and a Ό wide with one cell it held 50lb. and with two cells 120lb I used the small piece of Iron for this experiment as with a greater Surface the adhesion would have been too great for me to have been enabled to judge of the retentive properties With most respectful defference [sic] I beg leave to submit that if the grooves had been wider so as to have admitted of 4 coils instead of two the effect would have been still greater
I have sent the Tube with the Magnet for your inspection and am
Respected Sir Yours Most obediently
