Killed at St. Louis.
--One of the sufferers by the military riot at St. Louis, was Mr. Wm. P. Summers. formerly cashier of the Cataract City Bank, Paterson, N. J. He had gone to that city on business, designing to return home last week; but, through desire to witness the capture of the Secessionists, was present in the melee, and received a gunshot wound, from the effects of which he has since died.
