My dear Sir,

I have been instructed to request that you will favor me, for the Board’s information, with your Opinion whether fresh Water, deposited in Leaden Cisterns is likely to obtain any quality rendering it prejudicial if used for culinary purposes, or for drinking.-

I remain, | My dear Sir, | Your very faithful Servant | J. Herbert
