The above portrait of Benjamin Ellison, the murderer of Mrs. Seaman, of Penzance, is considered to be a good likeness, especially the upper part of the face and head; it was taken in the County Hall, Bodmin, while the unhappy criminal was receiving sentence of death for his awful crime. Ellison was a tall man, nearly six feet high, yet rather slightly formed. His aged was 61, and he was a native of Birkenshaw near Leeds, in the West Riding of Yorkshire. He had received a superior education, and had moved in a respectable station in life, having been connected with the manufacturing interest of his native county. We understand that his wife and family are still living, to deplore his untimely and disgraceful end. About two years since, he left his wife and home, in consequence of disagreements about pecuniary matters, and had not been heard of by her or his relatives until after his committal for the murder. The wretched culprit suffered for his crime on Monday last, and a full and authentic account of the execution is given in our fourth page.
