Faraday to Peter Henry Berthon   8 May 1858

Royal Institution | 8 May 1858

Sir

In reference to your letter of the 5th instant1 regarding the red light at the entrance of the river Garonne I have received no account of that light nor of its superiority over others. Not being aware of its construction either as regards the source of the light or the means employed to render the ray, red;- having indeed no data upon which to found any consideration, - I am unable to form an opinion respecting it relative to other red lights or indeed of the light itself2.

I am Sir | Your very faithful Servant | M. Faraday

P.H. Berthon Esqr | &c &c &c | Trinity House

This letter was read to Trinity House By Board, 18 May 1858, GL MS 30010/41, pp.401-2. The minute suggests that the letter Faraday sent underwent considerable revision from this text. It was agreed to write to the French lighthouse board for further details.
