es himself to Arabic studies, has discovered in
some Arabic manuscripts two works purporting to be by Euclid, which have
not been preserved in the Greek original, nor are any where referred to as

The Hungarian author. Baron Eoetvoes, has just published a work called
_Ueber den Einfluss der Neuen Ideen auf den Staat_ (On the influence of
new ideas upon the State). He argues that the students of social and
political science should confine themselves strictly to the method
received in the natural sciences, and employed there with such success;

We expect a treat from MORITZ WAGNER'S _Reise nach Persien und dem Lande

The second volume is announced as to appear in three weeks after the
first.

The second part of the third volume of HUMBOLDT'S _Kosmos_, has just

universe. Humboldt has already begun his fourth volume, and expects to
finish it before June next.

negotiations for his release, his journey from Kutahia to England, and his
tarry there up to sailing for America, with a portrait.
