 province, withm which they are actually situated. For in- 

 stance, the extreme northern part of Lancashire, one of the 

 Mersey counties, runs like a wedge into the Lake proAance, 

 and is truly a part of the latter in its physical relations. 



In some few cases, a little additional extension to the 

 limits of the provinces may be unavoidably given, where the 

 exact position of habitats on the borders of counties has not 

 been recorded in such tenns as to indicate within which 

 coimty or province the plant does really grow. Thus, in 

 the Floras or catalogues of plants foimd about Bristol, Bath, 

 Tonbridge Wells, Banbmy, and Glasgow, situate on the 

 borders of provinces, the localities of several species ai"e so 

 recorded as to leave untold their true position with relation 

 to county or province -boundaries. In these cases, the 

 doubtfully placed localities ai'e assumed to be within the 

 same county as the town itself, although the fact may be

 this assumption, must fall within a small distance, and can
