FIFTH PAPER, 
(First Paper, giving all explanations, Nat., March 1894, pp. 85-92.) 
In this paper I have sometimes added the distribution of rarer 
species by giving the Botanical Divisions for which they are recorded. 
Lincolnshire, according to the last Ordnance Survey, contains 
2,787°140 square miles of land, fresh water, salt-marsh, fore-shore, 
and tidal water—and nearly two-thirds of this lies in N. I have 
mapped out the county into eighteen artificial Botanical Divisions— 
aggregates of parishes round large places. Divisions 1-12 are in N., 
and 13-18 areinS, A glance at the numbers will tell an enquirer 
Whether the species is found in N. or S., or both. The number 
inclosed in brackets after the Bot. Div. number refers to the aggregate 
of known records for that particular Botanical Division. I have 
Placed a dash between the northern and southern Botanical 
Divisions, but have refrained from adding N and §&., as the 
numbers after these letters are the aggregate of records for the 
vice-counties. ‘The system will be more fully explained at a later 
period; here I may. only add that a geological or river-basin division 
Seemed unworkable.
