Newcastle 24th August 1846
My Dear Sir,
Many thanks for your communications of forwarded to Houghton-le-Spring. Pray have you received Mr. Dawson's letter, about which we were speaking when I saw you? I should like much to have a copy of it, though I feel sorry to trouble you.
I take it for granted that you will advertise me of any new routes traced for me after the 7th proximo, as soon as you know them.
Yours Truly,
James Thomson.
