He was about 75 years of age, and had been nearly fifty years in the army, and twenty on the Arkansas frontier. At the time of his death, he was commander of the 7th Military Department of the United States Army, and had held that station for several years, and was peculiarly calculated for the office, being thoroughly acquainted with the Indians, and Indian character, he always had their confidence, and by that means, kept up and maintained friendly relations with them on behalf of the United States. The St. Louis _Republican_ remarks that, "as a man, Gen. ARBUCKLE was honest and humane, loved and respected by every person with whom he had intercourse. No one pursued a more straight-forward course in all transactions. He was strictly economical in expenditures for the Government. His whole mind was engrossed with the present expedition of the 5th Infantry to the Brazos, and on the frontier of Texas, and he gave orders and directions for conducting, it as long as he was able to converse." * * * * * The CHEVALIER PARISOT DE GUYMONT, who belonged to the family of Lavalette, the illustrious Grand Master of the Order of Malta, of which the chevalier was one of the few surviving knights, has just died in the convent of St. Jean de Catane, in Sicily, to which the directing chapter of that celebrated order had retired. He distinguished himself in the expedition which the last grand master sent against Algiers towards the end of the eighteenth century; and General Bonaparte, when he took possession of Malta, demanded to see M. de Guymont, and received him with marked distinction. He was in the seventy-seventh year of his age. * * * * * SIR J. GRAHAM DALZELL, BART., died on the seventeenth of June in Edinburgh, aged seventy-seven years.
