Here, on p. 11 is given: 1 English line = 2.117 mm, 1 German line = 2.191
mm, 1 French line = 2.250 mm.

Dr. von Hayek refers to a "six inch ivory ruler by Janson of Russell
Street, London" that "shows that the English, French and German lines
differ in length".

                                 Best wishes
                                   Michael
