And more than this, thanks to the co-ordination of lessons well classified, there is, for each course of lectures, the means for arriving at full details in all particulars; the young students can talk amongst themselves and learn from each other, the student of moral science from the student of the natural sciences, the latter from the student of the chemical or physical sciences, and another from the student of the mathematical sciences.
