As Mr. Petrie, however, in his "Inductive Metrology," 

 gives the Pelasgic and cyclopean unit of measure, especially 

 as applied to Mycenae, Tiryns, and Etruscan tombs, to be a 

 foot of about ¥- (see pp. 85, 89, and 98)= 11-60, "as most 

 free from Eoman influence, and the same as the ancient 

 Greek; foot of sixteen Egyptian digits," I here append in a 

 short table some thirty-seven selected measures from the 

 buildings of Troy, Spata, Tiryns, Mycenae, and Etruria, 

 showing, I think, that the cubit unit of 19-85 inches is pre- 

 ferable to a foot unit of 11*60. These reductions are made 

 by the slide-rule, with suflicient accuracy for all practical 

 purposes. Some little allowance must generally be made 

 in the exactitude of most given measures of ruined build- 

 ings ; but generally an error of two or three per cent, on 

 either side will be suflicient: —
