Faraday to Jacob Herbert   27 April 1849

27 April 1849 | Royal Institution

My dear Sir

In reference to the ventilation of the Dungeness & Needles lighthouses I drew up ten questions (of which I send you copies) and sent them to the keepers of these lighthouses respectively¹. I send you the answers² by which you will see how impossible it is for me to form any judgement on such vague information. That from the needles is as scant as it is possible to be and that from Dungeness is in direct contradiction to Captn Madan & Mr. Wilkins in respect of the air tubes in the watch room. I think it would be better that I should go to one or both but that I could not do just now because of my lectures here. After the 10th of June I shall be free³. I believe the lanthorn itself requires ventilation & air[.]

I am Dear Sir | Very Truly Your | M. Faraday

Jacob Herbert Esq | &c &c &c
