[35] The pictorial part of the section of the great work of Sahagun in Florence was reproduced in facsimile by the late Mexican scholar, Sr. D. Francisco del Paso y Troncoso, for the Mexican government. Only recently has the work been received in Mexico, and we are under the greatest obligations to Sr. D. Luis Castillo Ledon, Director of the Museo Nacional, Mexico, for a copy which we have recently received, and which has been of such great assistance in the preparation of this study of Mexican mosaics. It is an Atlas, denominated Vol. V, of 158 estampas (plates). The plates relating to arts and crafts are to illustrate Libro IX, and include pl. lv to lxxvi.
[36] We refer the student to the edition of Lord Kingsborough, vol. I.
