There are 9 folding diagrams to face pages 49, 51, 59, 81, 94, 97, 98, 115, and 117; those facing pages 94, 97, 98, and 117, correspond to the 4 folding plates of the 1617 edition, the others are tables which in 1617 were printed in the text.
The numbering of the pages, though somewhat indistinct, seems to be correct throughout. In printing the signatures, however, C7 is numbered in error C6, and E3 has no signature printed.

This edition, published at Leyden, contains exactly the same matter as that of the Edinburgh edition of 1617. None of the plates, however, are engraved on copper. The decimal fractions are printed according to Simon Stevin’s notation; thus, for example, on p. 41 we have 1994 ⓪,9①1②6③0④ while in the 1617 edition it is printed 1994,′/9 ″/1 ‴/6 ⁗/0.
