384 : NOTICES OF BOOKS. 
announced in our * London Journal of Botany,’ vol. vi. p. 200, and this, 
the second, brings us to the monocotyledonous plants. Such of this class 
“as still remain untreated of, together with the Filices and allied 
ers, will form the earlier portion of the third volume. It is anticipated 
that the remainder of volume third will be required for supplementary 
and corrective additions to the two earlier volumes, likely to be supplied 
from the present rapidly accumulating stores of information on the 
subject of local botany in England." 
** The author feels anxious to complete these three volumes, including 
all the phzenogamous plants and ferns; because they will thus com- 
prise a full collection of arranged data, ready for the use of any other 
botanieal geographer, either in prosecuting similar researches, or in 
carrying them onward to more general views; and in order to render 
the three volumes as complete and useful as the plan of them may 
admit, in the light of a condensed arrangement of facts, it is earnestly 
recommended that competent botanists will either make public through 
the periodicals, or communicate to the author, any information which 
may tend to fill up deficiencies, to remedy defects, or to correct errors 
in either of the two volumes. e third volume, in which any such 
corrections, &c., can be made, will probably be prepared for the press 
in 1850 or 1851." 
We trust that many active British botanists of the present day will 
respond to this call; for sure we are that their materials cannot be in 
better hands for such a publieation than in those of Mr. Watson. The 
work is full of aeute observation, bearing on the geographie relations 
of plants, and the author is equally keen at detecting the faults and 
errors of his brother botanists, and recording them too :— 
“Hae! land o* cakes and brither Scots, 
From Gretna Green to Johnie Groat’s, 
If there’s a hole in a’ yer coats 
I rede ye, tent it: 
A chiel’s amang ye, taking notes, 
And, faith! he'll prent it.” 
British FLORA. 
A new edition (the 6th) of the * British Flora’ is preparing by Sir 
W. J. Hooker and Dr. Arnott, and will be ready by the spring of 1850.
