We respectfully aua Invariably decline to callattention to advertisements In the local department; but there is an advertisement In the city papers this morning that will call a great dealof attention vo itself. It announces that theconnection heretofore existing between the .ARtna luaurauce Company and J. B. Bennett, Esq., as general agent and manager of the Branoh, has terminated, and that the business will, for the present, be conducted by the President of the company, Mr. S. J. Hendee, a gentleman of Hartford, Connecticut.The sudden and wholly unexpected* termination of the connection of Mr. Bennett with the JEtna Insurance Company will be a surpriseand a sensation of the first order In Insurancecircles. If all the Internal Revenue officers in the city had been removed at once, and the Postmaster and District Attorney thrown in, the elrcnmstanoe would not have occasioned more remark than this will do.Mr. Bennett Is an old oitinen who has been prosperous and has built up an immense business. He occupies one of the palatial mansions in Clifton—the house formerly the home of Judge McLean—and was understood to be the Incarnation of methodical business.
