Is any thing more known about this pamphlet? As far as I can see, it is not in JND's Collected Writings. The title suggests that it was correspondence with who ever published it. Who would this be? I cannot find anything like it in JND's Letters either. Who were the publishers, Gospel Book Depot? Were they Exclusive publishers? They do not appear in the list of publishers of JND's works given in "Dates of J.N. Darby's Collected Writings" (Bible & Gospel Trust, Chessington, 2013).
Thanks
