Peter Henry Berthon to Faraday   12 February 1859

Trinity House | 12 Feb 1859

My dear Sir,

I am in receipt of your report upon the Water sent up from Hurst¹, and am requested by Capt Close to say that for many years the Light Keepers as well as the Gunners of the Battery there have had none other water for drinking than that alluded to, and that until now no complaint has been made against it.- he wishes however to know whether you consider that the deleterious effect of the Lead, which it is evident it contains, can be exhausted or neutralized by the use of any of the numerous descriptions of filters recently invented and if so what you would recommend as the most efficacious.

May I beg the favor of as early a reply as you can conveniently give me.

Yours | Very faithfully | P.H. Berthon
