ment of 1851 M. De Riviere stands in the first rank of French players Mr. Paulsen, whose reputation acquired an America had preceded him to this country, had proved himself the winner at the Bristol Meeting Mr. Steinitz was young player but lately known to fame as the prize holder in Tournament at the Vienna Club Mr. Dubois
had long been the foremost player of Italy and <Prince Ourousoff is one of the most skilful amateurs of Russia>. In other quarters the Committee were not successful, and had to regret the absence of Messrs. Heydebrand, Morphy, Petroff, Jaenisch, Harrwitz, Kolisch, St. Amant, Journoud, Laroche, and Max Lange, who, for various reasons, were prevented from taking part in the contests. With regard to British players, the Committee did not know until
the last moment the names of those who intended to com pete. The list comprised Messrs. Barnes, Blackburne,
Deacon, V. Green, Hannah, Lowenthal, M'Donnell, Mongredien, Owen, and Eobey. At length, on the 7th June,
the subscriptions having reached the sum of £570, and all arrangements being, as far as possible, complete, the Committee issued the following as their final programme<<>>>
