Paris, July 23. The Journal Officiel publishes the following proclamatioQ from the Emperor to the people of France : Frencumen - There are in the lifo of a people folemn momeats, wlien tbe nstioual honor is violently excited, presaes itself irresistibly, rises above all otber interestg, and pplies itself with tho single purpose of directing the destiniea of the natioD.
