Sad Accident.0n the evening of February 4th, while Mr. J. W. Black, of Boston, and his worthy assistant, Mr. J. L. Dunmore, were about to commence a lantern exhibition in Lowell, one of the gas-bags exploded with tremendous force, threw Mr. Dunmore high in the air and burned him sadly about the face and eyes, knocked Mr. Black senseless, drove a stick through the nose of the organist, and damaged the organ-loft, organ, and church considerably. Mr. Dunmore, at this writing, still lies suffering much and very low, but, with great care, it is hoped. may recover his sight. Mr. Black, though much hurt and quite deaf, faithfully applied restoratives to Mr. Dunmore the whole night of the accident, or the poor sufferer's sight would have been gone. Mr. Dunmore's many friends will be grieved to learn this, and with us heartily sympathize with him and hope for his speedy recovery. We have not yet learned the cause of the accident. When the explosion occurred, some old revolutionary female spirit innocently inquired of her neighbor if "that was the signal to commence the exhibition."
