DEATH OF MR. JOHN ENNIS VIVIAN, LATE M.P. FOR TRURO.—We regret to have to announce the demise of a very estimable and liberal-hearted inhabitant of Truro, namely, Mr. John Ennis Vivian, who has gone to his reward at the age of 83. For many years he had lived an almost secluded life, nevertheless he maintained a good establishment in Lemon-street, and was ever ready to assist in works of charity and schemes of public usefulness. He was a county magistrate and deputy-lieutenant for Cornwall, and for 22 years faithfully represented Truro in the House of Commons in the Conservative interest, and earned a reputation of being one of the very best of Committee men. After unsuccessfully contesting the borough in 1832, when he was defeated by only seven, Mr. Vivian was in 1835 returned at the head of the poll, having for his colleague Mr. W. C. Tooke (R), Sir R. Hussey-Vivian, Bart. (L), afterwards Lord Vivian, who in 1832 headed the poll, being defeated. At the general election in 1837 he was elected with Mr. Edmund Turner (L), at that time a resident of Truro, Mr. Tooke being defeated. In 1841 and 1847, Messrs Turner and Vivian were re-elected without opposition ; in 1852, when two Vivians and two Smiths contested the borough, the deceased gentleman and Mr. Augustus Smith were selected by the electors ; and in 1857 he withdrew from the representation. Since then he has taken no active part in public affairs, but has always evinced much interest in the welfare of the town and county. He was an excellent friend to the deserving poor, and Truro, generally, will miss so useful an inhabitant.
