   | The Era of 6 July 1862 (p.5) says that de Riviére 'has up to this time made even games in all his contests with his antogonist' (Anderssen). I record this as a soft result of 1-1. Even if it is meant to include his 1860 games with Anderssen, those results were even too, so these should also be. |  |  |  |
