By adopting these divisions it will be easy to record, on a single 

 sheet, all the Vice- counties in which any given plant] has been 

 observed, by simply marking off the number and name, while 

 space will be left after each name for an entry of the authority or 

 exact locality if necessary. Further, I believe, it will be a great 

 advantage to students to have the " Districts " named instead of 

 merely numbered ; and also it will be much more easy to compare 

 the distribution of species in Grreat Britain and Ireland now than it 

 was formerly when totally different divisions were adopted.
