done, never losing the thread of the narrative, and maintaining the interest in the hero throughout, implies no ordinary tact and skill; for the book is remarkably readable, and there are few pages which are not enlivened by some anecdote or lifelike touch. Nor is it less remarkable for accuracy than for the other qualities already mentioned. The writer has used it constantly for many years, and has never yet discovered a mistake of any moment. Perhaps it would have been better if the secondary treatises of which we have spoken had been relegated to Appendixes; but this is directly opposed to the German method, and we must accept the work as we have it. There are indeed already nineteen Appendixes to the original work, as follows i. Family documents. 2. Marianne Mozart. 3. Testimonials, eulogistic poems, articles, &c. 4. Dedications. 5. Mozart's letters on his journeys. 6. Text of his church music. 7. Arrangements and adaptations of ditto. 8. His cousins. 9. Mozart as a comic poet. 10. Mozart and Vogler. 11. A letter of Leopold Mozart's. 12. Mozart's letters on the death of his mother. 13. The choruses for "King Thamos." 14. The text of "Idomeneo." 15. Alterations in that opera. 16. Mozart's letters to his wife. 17. The Requiem. 18. Mozart's residences in Vienna. 19. Portraits. Of these it has been considered necessary to retain only Nos. 2, 7, and 19, which form Appendixes 1, 2, and 3 of the present edition. Another has been added: namely, a classified list of the whole of his works, according to the complete edition now in course of publication, with the references to the invaluable Catalogue of Köchel. With these exceptions the English translation is exactly in accordance with the German original. {PREFACE.} A word of special praise is due to Miss Townsend, the translator, who has performed her laborious task with great accuracy and intelligence, and has established an additional claim on the gratitude of the student by her exhaustive Index, in which the original work is very deficient.
