With reference to your Report dated 26th May last¹, upon Dr. Normandy’s Patent Marine Aerated Fresh Water Apparatus², I am directed by the Lords of the Committee of Privy Council for Trade to transmit to you the accompanying Copy of a Letter from Mr. Alexander Gordon, Civil Engineer, on the subject of this Invention, and of another Apparatus for distilling Sea Water by means of the Sun’s rays through the Agency of a Brass Reflector or “Thermheliostat”.

My Lords desire me to express their hope that you will be able to favor them with you opinion as to the reflective merits of these two Inventions, more especially with reference to their Applicability to Lighthouses.

Any further information on the subject of Mr. Gordon’s Apparatus shall be procured and forwarded, if desired[.]

I have the honor to be, | Sir, | Your obedient Servant | T.H. Farrer

M. Faraday Esqre. F.R.S. | &c &c &c | 21 Albemarle Street
