In the Table of ERRATA at the end of Vol. I. it was said, “That Plate XLVII. represented a different Orrery from the one described.” This was a mistake the Printer was somehow led into: for the Orrery there represented is the right one, and corresponds with the description.

In FLAX-DRESSING, plans of two machines relating to that article were referred to, but which several circumstances now render it difficult for the Editors to give. It is therefore hoped these will be dispensed with, as they are not of the most general importance, and the article is sufficiently explained and illustrated without them; and especially as 10 plates more than the proposed number, and 16 pages of letter-press, are given gratis.

DIRECTIONS to the BINDER.

1. Be careful in cutting the book, not to pare too much off the margin; as it was necessary, in several places, particularly in BOOK-KEEPING, to enlarge the page beyond the measure of the rest of the book.

2. Title-pages for the Three Volumes are printed. Place them respectively at the beginning of the Volume; and after the title in Vol. I. insert the Preface.

3. In BOOK-KEEPING, Vol. I. cancel pages 585, 586; and in their place insert the leaves marked with an asterisk and inclosed with parenthesis, viz. (*585) (*586), (*A) (*A), (*B) (*B), (*C) (*C), (*D) (*D), (*E) (*E).

4. Insert the Plates as directed below.
