To George Biddell Airy

My dear Sir

If it would suit your convenience I should be happy to make arrangements for our experiments1 with the Induction coil on some day of the week after next. I should like if possible to shew you the most powerful arrangement yet devised and to effect this should have to communicate with the deviser. Would you kindly tell me on what days among the following you would be at liberty to come to the Royal Institution—Monday 27th. Tuesday, Friday or Saturday? I can then fix upon upon the particular day which will be most convenient to Mr Bentley2 who has introduced the most recent improvements on the coil.

very sincerely yours | John Tyndall
