Robert Mallet to Faraday   26 April 1856

Delville, Glasnevin | Co Dublin. | 26 April 56.

My dear Sir

After consideration - if you will still permit me, I should gladly avail myself of your very kind offer to ascertain, if Dr Bence Jones, would permit his Rhumkorf’s Coil to be used for a few days, in making some preliminary experiments as to its powers & suitability &c. for igniting powder in my Experiments upon the Earthquake wave period, at the Governments Premises Holyhead. - the accountability as to safety, return, and expense of transit resting of course with me. I shall have to obtain a coil for my own special use I therefore would limit my use of that referred to - to those preliminary trials[.]

Faithfully and | with much esteem | yours | Robert Mallet.

Prof. Faraday. | &c &c &c. | Roy. Inst. Gr Brit. | Albemarle St | London.
