inately full list of their species or flora. And it was 

 further desired, for sake of comparisons between their 

 floras, that each one of these provinces should include 

 some portion of coast Une. Some slight differences 

 would have been made in tracing out the Scottish pro- 

 vinces, if the botanical records relating to the counties 

 and islands of that portion of Britain had been more 

 complete, especially with reference to the commoner 

 plants. Though many of the blanks in the areas of spe- 

 cies, as traced out by provinces, can now be filled up, 

 there are still too many remaining. The lists of species 

 are yet much short of completeness and correctness for 

 the provinces of North Highlands, West Highlands, 

 Lakes, South Wales, and in less degree for some others. 

 The numerals given in the line of ' Area,' under the 

 name of each species in former volumes, represent 18 

 local floras, one for each province. With the " additions 

 and corrections " introduced into volume third, those nu- 

 merals may be readily converted into local lists or floras 

 for any or all of the provinces ; such as would be approxi- 

 mately complete, though doubtless open to emendations 

 by botanists with the requisite local knowledge. Of 

 course such lists would represent only the state of infor- 

 mation at the date when the corresponding portion of 

 this work was written. Some blanks in the line of nume- 

 rals are being filled up each successive year ; and from 

 time to time it is ascertained that some of the nos. were 

 erroneously entered, through mistakes about the species 

 on the part of local observers or otherwise. To form the 

 list for any separate province, it is easy to take a copy of 

 the ' London Catalogue of British Plants,' and to check 

 the name of each species in accordance with the corre- 

 sponding no. of the province in the line of ' Area.' 

 Eighteen lists thus formed would afford serviceable data
