Mexico the work for science aud the arts which Napoleon 1. accomplished in connection with the expedition to Rgypt. The Minister of Public Instroction, in u report addressed to Emperor, proposed the appointinent of a comniizsioner to preparo instractious for an expedition, and to superintend the publication of the resulta of observations on thut country, made iu connection with the army. In regurd to the minerals and orincs of Mexico, the report gays :— “What bas been doro by mining assons 13 worthy of praise, but what is known t of the mineralogical wealth of Mexico is mubtedly the sinullest part of that which s. ‘The sites thus fur turned to profit are xe, fur the most part, which hozurd has preted.

Not even a graduating clues is allowed to muke any demunstration of that kind of their appreciution of a teacher under whoso direction they received their eduentiou. Such a rule appears unnecessarily arbitrary ond sovere, and would hardly be thought of in any other locality than the “city ol notions ;” atbert Boston has some most excellrnt notions, and especially about school teaching. f +. oe Senoots ix TeLanE Covunty.—A eorrespondent of the Visalia Deda cails particular attention to the pleusing fact, and one whieh speaks volumes for the people of Tulare, that while in 1860 there were only five schools in the county, in 1865 there were fifiy, and increasing in numbers.
