Murder of an American.
--Hon. Joseph L. White, of New York, formerly a member of Congress from Indiana, was killed at Realejo. Nicaragua, on the 5th ultimo, by a Canadian named Gavett. Mr. White had gone to Central America on professional business, and the difficulty was caused by some misunderstanding in relation to business matters connected with a large India rubber contract with an American company, of which Mr. White was counsel and agent. Mr. White was shot in the knee, on the evening of the 5th of January, soon after landing from the Pacific steamer.--The wound was so severe that amputation was found to be necessary, but was ineffectual as a cure. He lingered for a few days, and died on the 12th of January.
