A list of corrigenda et addenda follows, and the work com- 
bines with a Tabula Phytogeographica, in which the 563 species 
are enumerated according to countries; from which it re- 
sults that Europe possesses no one species, Australia, 
1-27th; Africa, 1-27th ; Asia, 1-5th or 1-6th; America, 
3-Aths. 
Wherever the genera are extensive, numerous in species, - 
the author has given a Conspectus Specierum. The specific 
characters are drawn up, and the synonyms selected, with 
much care; the descriptions are full, and so far as we have 
tested them extremely accurate; and the whole work may be © 
held up as a model for a Monograph. We understand that a - 
Supplement to the volume is preparing, and we have been . 
informed that it is Dr. Miquel's intention to prepare a History - 
of the Genus Ficus, and we trust of the allied genera, on the © 
same excellent model.
