DEATH OF A VETERAN. General William Henry McNary Dies of Heart Failure. General William Henry McNary, a veteran of the late war, died at his residence, 101 State street, at 1 o'clock in the afternoon. He was af- flicted with pneumonia in a slight form, but died primarily of heart failure, though he was not taken seriously ill until last Sunday, when he be- came confined to his bed. His widow, two sons and a daughter and three grandchildren survive him, the two sons, William Henry and Isaac Newton, being married and living with their respective families the one in Brooklyn and the other in Jersey City. The funeral services will be held to-morrow night, at 8 o'clock, at the residence, and the interment, which will be private, will take place on Sunday morning in Greenwood. General McNary was born in Brooklyn about 59 years ago and was brought up in this city. For a long time he had been captain in the Four- teenth Regiment. He went to the war as lieuten- ant colonel in the One Hundred and Fifty-eighth New York State Volunteers and remained until its close, when he received the brevet rank of general for meritorious service. During the war he was principally stationed in North and South Carolina. He was one of the most enthusiastic advocates of the formation of the Grand Army of the Republic, of which he was the first second officer. In virtue of the part he thus took his portrait has ever been displayed at the headquar- ters of Rankin Post, of which, prior to his de- parture for Europe eight years ago, he was always a prominent member.
