THE Treatise on the Particular Examen of Conscience, by Father Luis de la Palma, of the Society of Jesus, fully explains the nature and the use of this Spiritual Exercise, as it was taught by St. Ignatius in his book of the Exercises. Since the time of St. Ignatius, the Particular Examen has been adopted to a considerable extent, both by Religious and by persons in the world, aspiring to perfection, and, very generally, by the active Orders which have sprung up since the time of the first French Revolution.
