Trinity House, London, | 28th March, 1856.

Sir,

The Elder Brethren being desirous of obtaining such practical information in respect of the best Construction of Fog Bells and the Appliances to be used in sounding them, as may enable them to adopt generally a more efficient system than that at present in use which has at several of the Light House Stations been found defective,- I am directed to signify their request to be favored with your opinion as to the best Scientific Machinist with whom you would recommend that they should place themselves in Communication on this Subject.-

I am, Sir, | Your most obedient Servant, | J. Herbert

M. Faraday Esq: F.R.S. | &c &c &c
