Juniper, Aquilegia vulgaris, Caltha palustris, etc. 2. Those 

 which are confined to Europe and India. These, again, be- 

 long partly to the Mediterranean Flora, as, for instance, Celtis, 

 Quercus Ilex, Olea Europaa, Myrtus communis, etc.; and 

 partly to that of Europe north of the Alps, including the 

 greater number of herbs and small shrubs. Meanwhile we 

 shall here confine ourselves to subjoining a list of 232 British 

 plants which extend into India. Many of these require a 

 more critical comparison ; but we are convinced that the er- 

 rors which may be detected in our enumeration are too few 

 to invalidate the important general law. The list, indeed, is 

 very far from complete, as we have omitted all plants regard- 

 ing which we are not tolerably certain.
