One may learn from the notes of Foulché-Delbosc that the Orígenes del teatro español of the younger Moratín has not been published in complete form, and that those who prepared or censored the 1830 edition of Moratín's works caused several passages to be altered. Let us look then at the manuscript, which is easily available in the Biblioteca Nacional in Madrid, and see for ourselves the changes that have been introduced. At the beginning is an unsigned statement, in a hand different from that of the manuscript, which declares that the first edition of the Orígenes was printed, not from Moratín's original, but from a copy thereof (now in the Library of the former Royal Palace). This copy is practically identical with the manuscript of the Biblioteca Nacional except that it lacks the six hojas which contain the Indice de las piezas contenidas en el siguiente catalogo. The six sheets follow page 130 of the latter manuscript and are not numbered.
