We have received Cassell's New Popular Educator, Vol. VI (Cassell
and Co.) It contains instruction, adapted for the use of private students, in physical science of various kinds, mathe- matics, English literature, &c., French, German and Italian, Greek (the grammar with exercises) and Latin (the Agricola of Tacitus, 542). It would be convenient, one would think, to include a whole book in a volume. The idea of contubernium, in chap. v., is hardly represented by " comrade," a word which gives an impres- sion of equality. Agricola bore precisely the same relation to Suetonius as an aide-de-camp to his General. You would hardly -call an aide a "comrade."—From the same publishers we have also received Cassell's Storehouse of General Information, Vol. I., A—Bear.
