Faraday to Marc Isambard Brunel   24 May 1839

R Institution | 24 May 1839

My dear Sir

I am very sorry that the evil continues so powerful with you as your letter¹ describes but I do not know what to say more than I have said to you & the secretary & others. Abundant ventilation - the use of a little chlorine when it can be employed, & of ammonia also to refresh the men are what have occurred to me & these you are trying I think as far as you can. If I could say more I would say it to you for your sake & for the Tunnel and would not wait for the Directors application for professional assistance[.]

With respect to the latter, your directors must excuse me. I never now take professional business and am unable to attend to the matter in that form. But believe me that if any thought occurs to me which can be in the least useful to you, I will not lose a moment before communicating it to you[.]

Ever My Dear Sir | Most Truly Yours | M. Faraday

M.I. Brunel Esq | &c &c &c
