I beg to acquaint you that I have written to Mr Jones the proprietor of the Adelaide Gallery <1> on the subject of a private room for yr Electro magnetic Engine and he replies by stating that he has vacant rooms and wod be happy to make arrangements with you for the renting one of them.
I take the liberty of informing you that Profr Grove <2> proposes delivering in the theatre of the Royal Institution on the 10th of February a discourse on Electro Magnetic Engines would not this be a good opportunity to introduce yr arrangement to the Scientific world
I remain Sir Yr Obedient Servt
