   | Notes: |  
   | Only partial results available. Although van Winsen gives final scores for Mackenzie (19/22), Barnett (17/22) and Ware (16/21), we don't know how many opponents they had, or even whether they played the same opponents. This was a double-round all-play-all but the number of players is not known, and if larger than 12, then a full quota of games would have been more than 22. The Illustrated London News of 12 Feb. 1870 (p.186) says that Barnett and Ware were tied at 16/21 and so had to play off for second and third prize. The 26 Feb. 1870 issue (p.235) indicates that after the play-off Barnett's scores was 17/22, the final score given by van Winsen. Thus, I am supposing that they had already played their two games, but played another one to break the tie. I am also guessing that Barnett and Ware would have played even. I record here only the result of this play-off game, and the result of pairings for which scores of both games are known (apart from possibly missing draws). |  |  |  |
