Conclusion
Lord Tennyson's prize has not yet been decided, owing to the absence from town of Mr. H. Gwinner, who tied with Mr. MacDonnell. (4)

At some point MacDonnell did play Gwinner. The British Chess Magazine recounts "In 1886 he won the 'Tennyson' Competition of the B.C.A. meeting, after a tie with Mr. Gwinner." (5)
