We believe that Geo. A. Curtis, John McDonald, Thos. Aylwood, George Lincoln, Timothy Burns, Henry Otten, George W. Brown, Wm. Butler, George W. Taylor, Owen Burns, Thos. Belman, Neil Gray Mellis, Asa F. Collins, Wm. Harmer, Thos. Keirnan, Mathew Cahill, Geo. N. Gedney, came to their deaths by gun shot wounds, from balls fired by the Military during the riot before the Opera House, on Thursday evening, 10th May inst., by order of the civil authorities of the city of New York; and that the circumstances existing at the time justified the authorities in giving the order to fire upon the mob. We further believe that if a larger number of the Police had been ordered out, the necessity of a resort to the use of Military might have been avoided. NEW YORK, May 14, 1849. JAMES H.
