been attained in any other country. 
One of those maps (South Dublin) 
has been printed by the Ordnance 
Survey Department for the Irish 
Board of Agriculture, and the other 
maps have been published either by 
the Royal Geographical Society, or 
by the Geographical Society of 
Edinburgh ; and the broad-minded- 
ness of these learned societies in this 
regard has placed plant geographers 
of all nations under a debt of gratitude. 
It is, however, satisfactory to know 
that the Irish experiment is being 
followed with regard to the publication 
of vegetation maps of Great Britain ; 
and that two maps, of the Peak 
District, uniform in area and size 
with the new series of Ordnance 
maps, are to be printed and issued 
by the Ordnance Survey Department 
immediately, and accompanied by an 
explanatory memoir.
