Letter from WSC (105 Mount Street) to David Thomas expressing surprise at Thomas's opposition to the candature of Ivor Guest's [later Lord Ashby St Ledgers and Lord Wimborne (2nd baron, 1st viscount)] for Cardiff [Wales] in view of the fact that Guest is more "advanced" in his views than WSC, to whom Thomas has pledged his full support. Urges Thomas to put aside personal considerations and support Guest for the sake of the cause of Free Trade. MS copy in WSC's hand.
