Suicides of a Grandson of Senator Crittenden.
--The Pensacola Observer, of the 26th, says:‘ A young man named Coleman, from Tallahassee, a grandson of ex-Senator Crittenden, of Kentucky, attached to the ranks of one of the companies of the 1st Florida Regiment stationed six miles below here, cut his throat yesterday from ear to ear, while under a state of mental derangement. He was but about twenty-six years of age, in the very bloom of his manhood, and possessed fine abilities, and a rare order of talents. We can't but regret this sad occurrence, and the untimely demise of a brave and chivalrous soldier and gentleman. His body, accompanied by friends. leaves to night or to-morrow for Tallahassee.
