The _Westminster and Foreign Quarterly Review_, for January, 1851, contains a great article on the controversies occasioned by the recent movements of the Roman Catholics in Great Britain. It is very long (making sixty pages), and very able. Reviewing the battle, from an unusual, and to most people perhaps a not very accessible, point of view, it throws a startling light on many matters forgotten or ignored by the more immediate combatants. It may, therefore, be perused with interest and advantage by partisans of every shade. Protestant and Catholic will find their account in it, especially as helping them to information of which they are greatly deficient--a knowledge of each other's strong points, as well as their weak ones.

The battle in the foreground may be about candlesticks, surplices, and genuflexions. But there are involved many things infinitely more vital, as the author of this "Battle of the Churches" will be admitted to have illustrated with great success.
