My dear Sir,

I am directed to forward to you the accompanying Samples <(3)> of Drinking Water which has been received from two of the Corporation’s Light Houses where it is kept in Leaden Cisterns, and to request that you will favor the Elder Brethren by making an examination of the Water, and reporting the result, at your convenience; with a view to ascertain whether in the contents of either of the Samples, there is anything deleterious to the health of the persons using the same.-

I am | My dear Sir | Your very faithful Servant | George Herbert | Assistant Secy

M. Faraday Esq. D.C.L | &c &c &c
