are to be expected is not known; but supposing the whole 
number of genera known to Dr. Endlicher to be 8000, it may 
be supposed that the work will be brought to a close in seven 
or eight more parts, or in about a year and a half. The 
period of its completion will form an era in the history of 
systematical Botany. Independently of its great importance 
on account of the singular skill and care with which it is 
written, it possesses an additional value in consequence of 
the numerous references to books in which descriptions and 
figures of the genera may be found. 
Simultaneously with this great work the same indefati- 
gable author is publishing an Zconographia Generum plan- 
tarum, or illustrations of the genera described by him. It 
appears in 4to. or folio parts, with uncoloured figures exe- 
cuted in outline by artists of the highest eminence. Seven 
parts have now appeared, and the number of the last plate is 
84. Independently of the other important materials of 
which Dr. Endlicher is able to avail himself for this work, he 
has access to the beautiful series of drawings of New Holland 
plants, executed by Mr. Ferdinand Bauer during Flinders’s 
expedition, and bought by the Austrian government upon his 
death. The originals are somewhere in this country, but 
where deposited I am not at present able to state. It is well 
known that in 1813 an attempt was made by Mr. Bauer to 
publish them in this country, but no effectual support was 
afforded him by either the men of science or the government 
of the day ; and although the plates were engraved with his 
own hand, and with exquisite skill, the publication never 
proceeded beyond three numbers. It is impossible not to 
feel it a national disgrace that such valuable materials, col- 
lected at the cost of the English government, should onl 
make their appearance nearly thirty years after their acqui- 
sition, and then by the energy and zeal of a learned foreigner.

The second part of this valuable work has reached Eng- 
land. It proceeds from Caryophyllee to the middle of 
Leguminose, in the order of DeCandolle’s arrangement, and 
like its predecessor, exhibits equal care and talent in the 
determination and definition of the genera and species. It 
is rich in new species from California and Oregon, collected
