A notable feature in Mr. Lewis's translation is his division of the chapters into short paragraphs. But it appears that he rearranged the division during the process of printing, with the result that a large number of references were wrong. No labour has been spared in the correction of these, and I trust that the present edition will be the more useful for it. In quoting the Way of Perfection and the Interior Castle (which he calls Inner Fortress!) Mr. Lewis refers to similar paragraphs which, however, are to be found in no English edition. A new translation of these two works is greatly needed, and, in the case of the Way of Perfection, the manuscript of the Escurial should be consulted as well as that of Valladolid. Where the writings of S. John of the Cross are quoted by volume and page, the edition referred to is the one of 1864, another of Mr. Lewis's masterpieces. The chapters in Ribera's Life of St. Teresa refer to the edition in the Acts of the Saint by the Bollandists. These and all other quotations have been carefully verified, with the exception of those taken from the works on Mystical theology by Antonius a Spiritu Sancto and Franciscus a S. Thoma, which I was unable to consult. I should have wished to replace the quotations from antiquated editions of the Letters of our Saint by references to the new French edition by P. Grégoire de S. Joseph (Paris, Poussielgue, 1900), which may be considered as the standard edition. In note 2 to Chap. XI. Mr. Lewis draws attention to a passage in a sermon by S. Bernard containing an allusion to different ways of watering a garden similar to St. Teresa's well-known comparison. Mr. Lewis's quotation is incorrect, and I am not certain what sermon he may have had in view. Something to the point may be found in sermon 22 on the Canticle (Migne, P. L. Vol. CLXXXIII, p. 879), and in the first sermon on the Nativity of our Lord (ibid., p. 115), and also in a sermon on the Canticle by one of St. Bernard's disciples (Vol. CLXXXIV., p. 195). I am indebted to the Very Rev. Prior Vincent McNabb, O.P., for the verification of a quotation from St. Vincent Ferrer (Chap. XX. § 31).
