Sudden Death.

Yesterday, about 7 1/2 o’clock p.m., Mr. Peter Slavan, formerly a watchman at the Patent Office, died, after a few hours' illness, at the residence of Mr Flannigan, on Eleventh, near E street, in whose family he had been a boarder about nine months. At seven o'clock yesterday morning Mr. S was in as good health as usual, apparently very lively and jesting with his friends. He walked out awhile and returned to his room. About 11 o’clock his landlady heard a scream and went to learn the cause, and found that he had been taken sick suddenly, and had rushed down stairs for aid, and was standing at the door holding on to the frame and trembling violently. She assisted him to his bed and sent for assistance. Dr. Dyer and Rev. Messrs. and O'Toole and Boyle were soon on the spot, and afterwards Dr. Stone. All the aid that medical skill and experience suggested was rendered. He continued to sink until about 7 1/2 o’clock last evening, when he expired. Mr. Slavan was a native of Ireland, but left his native country at a very early age. He was remarkably temperate and a strict observer of his religious duties. He was about 50 years of age, and of a very robust habit. The physicians attending him decided that his disease was apoplexy. He has no relatives in this country except a half-sister somewhere in New York. The funeral will take place this afternoon at 5 o'clock.
