[70] In a dispatch of the 1st March, 1866, M. Nigra informs General La Marmora that, conformably with his authorization, he endeavored to broach the question of the exchange of the Danubian Principalities for Venetia. He showed the advantages which this solution would have for France and England, who would thus see the two programmes of the wars of the Crimea and Italy peacefully accomplished. The minister adds that the Emperor Napoleon III. was _struck with this idea_. La Marmora, p. 119.
