Captain Lean, R.N., of the Emigration Board, attended recently at the Mansion-house before the Lord Mayor to prosecute six charges preferred against Messrs. John Course and West, shipowners and brokers, of No. 9.7, Leadenball-street, for receiv ing certain sums of money from numerous passengers for providing them with passages to New Zealand in the ship ' Devonshire,' and failing to do so.
