Note 2 — BOOK IV.

The following are the equivalents of the measures mentioned in this book. It is not always certain which "foot" or "fathom" Agricola actually had in mind although they were probably the German.

Greek—

Dactylos=.76inches16=Pous=12.13inches6=Orguia=72.81inches.

Roman—

Uncia=.97"12=Pes=11.6 "5=Passus=58.1 "

German—

Zoll=.93"12=Werckschuh=11.24"6=Lachter=67.5 "

English—

Inch=1.0 "12=Foot=12.00"6=Fathom=72.0 "

The discrepancies are due to variations in authorities and to decimals dropped. The werckschuh taken is the Chemnitz foot deduced from Agricola's statement in his De Mensuris et Ponderibus, Basel, 1533, p. 29. For further notes see Appendix C.
