Mackoull lived in White Lion-court, in Throgmorton-street, and the occasional intimacy appears to have continued till 1807, in which year, on March 13th, Lund had a benefit at the Woolwich Theatre, when the Bolognas, Grimaldi, and Norman, were to enact Don Juan. Mackoull accompanied John Bologna from London to Woolwich on the morning of the 13th; the performances went off well at night, and the whole party continued there till two o'clock in the afternoon of the 14th, when Mackoull left, Grimaldi having promised to dine with him on the Wednesday following. It so happened, that on the night of the 12th of March, or on the morning of the 13th, the Edinburgh mail-coach was robbed of a parcel, forwarded by the Newark bank to Messrs. Kensington, of Lombard-street. The parcel contained bank-notes and bills to the amount of 4500_l._, payable in London; and was, as afterwards transpired, stolen by a man, then travelling in the mail, named Treble, who, to avoid hanging, destroyed himself. A returned transport, named Duffield, received the bills, and a strolling player, named John Knight, who, under the assumed name of Warren, at Salisbury and other places enacted Othello, and other principal characters. He became the negotiator of some of the bills by forging or indorsing them in his own theatrical name of Warren, and contrived to discount one at Burton-upon-Trent, on March 17th; another at Uttoxeter, on the 18th; a third at Congleton, on the 19th; and a fourth at Wirksworth, on the 20th. Information that some of these bills had been discounted at the above principal banks having transpired, and a description of the person who had negotiated them being transmitted, Mackoull's personal appearance was extremely similar to that of the delinquent described; and he was apprehended accordingly at his house in White Lion-court, on April 3rd, taken to the Brown Bear, in Bow-street, and on that evening charged at Bow-street with felony, having robbed the mail, and with forgery of the indorsements on the bills asserted to have been negotiated by him. He was remanded to the 8th, on which day Mackoull was again placed at the bar, Mr. Alley as his counsel, and Mr. Harmer also appearing in his defence. But it was not until the third hearing, on the 11th, that specific charges were made against him, and he was sworn to be the person who had obtained the money for the bill discounted at the Congleton bank on March 19th. Mackoull, being in possession of the charge, was enabled, to prove an _alibi_ most satisfactorily, as Grimaldi and his wife had dined with him on the 18th of March. Mrs. Grimaldi had left them at five o'clock, to sustain her part in the Oratorio that evening at Covent Garden Theatre, and Joe had remained with Mackoull till eleven that night; it was therefore clear that he was not the person who had negotiated the bills, nor was he the party who had robbed the mail, as he had evidence in John and Louis Bologna, Grimaldi, Norman, and many
