Plotinua Psychic and Physical Treatises. Translated by Stephen Mackenna. Vol.

II. (P. Leo Warner. 21s. net.)— In this second volume Mr. Mackenna has translated the Second and Third Enneads. He frankly confesses " that he does not pretend to be perfectly satisfied that he has himself under- stood every passage of which he has been obliged to present a rendering." Plotinus is extremely obscure at times, because his modes of thought are profoundly unlike those of twentieth- century Europe. However, Mr. Mackenna's version reads well. It is finely printed.
