The Ordnance Survey of the British Isles being projected on the statute mile of 
5280 feet, the column B. affords a ready means of comparing the Ordnance Survey 
with any foreign Government map. Comparing the Government Survey of 
Belgium with the Ordnance Survey of Ireland, place the scales one above the 
other, with the names against each, thus : — 
Belgium 3*168 
= £ nearly, 
Ireland .. .. .. .. 6*000 
shows at once that the Belgian Survey is on one-half the scale of the Irish 
Survey. 
Russia (Tver) 0*754 
Scotland .. .r 6*000 
The Russian Survey is, therefore, | the size of that of Scotland. 
All the foreign maps are projected on the scale C. 
Column A. of the Scales will be found very useful in obtaining the proportion 
of the inch to a mile from Maps or Charts on which the Natural Scale only is 
given. Enter the column A., and find the nearest number to the given Natural 
Scale, and on the same line towards the right will be seen the proportion it bears 
to the statute and geographical mile.
