We received last night the Paris Papers of Saturday, from which we have given extracts in another column.

The Journal des Debats has copied from the Revue Protestante an interesting letter from Humboldt, the celebrated traveller, to M. Ch. Coquerel, Pastor, at Amsterdam, on the proportion which the Catholics and Protestants of America bear to each other, on the different races in America, and the languages spoken in that continent.

The details are to be given in the third volume of his Travels to the Equinoctial Regions, which is about to appear.

The following are a few of his statements:—
