BOTANICAL INFORMATION. 155 
Each Order is headed by a very valuable history of its geo- 
graphical distribution over the globe, which shows an intimate 
acquaintance of the author with this subject on its widest 
scale: and this, in regard to Ranunculacee alone, occupies 
fourteen pages :—then follow seven Lists; of which the 1st 
records the proportions of Ranunculacee relatively to lati- 
tude. List 2, Proportions of Ranunculacee varied locally. 
List 3. Comparative frequency of British Ranunculacee. 
List 4. Number of Ranunculacee in the districts of Britain. 
List 5. Number of Ranunculacee in the regions of Britain. 
List 6. Number of Ranunculacez as varied by altitude, in 
Britain. List 7. Number of British Ranunculacez in other 
countries, 
Next comes the full consideration of each species of the 
several genera, Following the name of the plant is: 
_ 1. Disrricrs. A simple enumeration of certain districts in 
which the species under consideration has been ascertained 
to grow. 2. Froras. A paragraph enumerating the local 
Floras and Catalogues in which the same is mentioned. 
3. Specimens. Localities from which specimens are pre- 
served in the author's herbarium. 4. UNCERTAIN LOCALI- 
TIES. 5. Brirain: under which head the distribution of 
the species in Britain is slightly sketched out. 6. GENERAL 
Disrrisurioy.—The concluding paragraphs, preceded by the 
names of the districts, embrace a miscellaneous compilation - 
of localities brought together from various sources of infor- 
mation. 
With each species are given two diagrams: the — 
Presenting a miniature map of Britain divided into eighteen 
Sections or districts, by one longitudinal and several trans- 
verse lines; so drawn as to throw the counties into that 
number of groups; while the second figure shows the abso- 
lute and comparative heights attained by the highest hills of 
the respective districts; the cones of this figure correspond- 
mg with the districts on the map, as numbered from south
