 The second edition has the date 1723 on the title page, but the "Proemio" itself is dated 20 January 1725, so the effective publication date must have been later than that.A third edition (a new facsimile reprint rather than a new edition) was printed in Mexico in 1943 by Salvador Chávez Hayhoe.The only addition was a title-page identifying the data relevant to the reprint.
