Was not Sir George Jackson "Junius?"

Among the names which have been put forward as claimants to be "Junius," I beg to propose the name of Sir George Jackson, who was, I believe, about that time Secretary to the Admiralty. I shall be glad to know what obstacles are opposed to this theory, as I think I have some presumptive evidence (I do not call it strong), which seems to show either that he was "Junius," or a party concerned. [We insert this communication, knowing that our correspondent is likely to possess such evidence as he alludes to, and in the hope that he will be induced to bring it forward.]
