_Geographical Journal_, Sept. 1910

For the loan of blocks I am indebted to the Académie des Inscriptions
et Belles-Lettres (fig. 21), to the German Imperial Archaeological
Institute (fig. 9), to the Royal Geographical Society (fig. 36), and
to the Royal Institute of British Architects and the Editors of the
_Transactions of the Town-Planning Conference_, 1911 (figs. 7, 8, 17,
30, 32, 35). Fig. 11 is from Mr. T.E. Peet's _Stone and Bronze Ages in
Italy_. The other 26 blocks have been prepared for this volume.




TABLE OF MEASURES


The following figures may be found convenient by readers who wish to
take special account of the dimensions cited in the following pages,
and may also help them to correct any errors which I have unwittingly
admitted.

1 Roman foot = 0.296 metres = 0.97 English feet. For practical
purposes 100 Roman feet = 97 English feet.

1 Iugerum = 120 x 240 Roman feet = 116.4 x 233.8 English feet. For
practical purposes a _Iugerum_ may be taken to be rather over
2/3 of an acre and rather over 1/4 of a hectare, and more exactly
2523.3 sq. metres.

1 Metre = 1.09 English yards, a trifle less than 40 ins. 402.5 metres
