BRITISH FRESH- WATER ALG^. 
In answer to various communications as to the progress of this 
work, we are able to announce that the plates of Part IX. are in 
the printer’s hands, and will shortly be ready for publication. 
Part X. is also in an advanced condition, and this will contain the 
Bhodophyceoe, which, with supplement, introduction, glossary, and 
Index, will complete the work. It is hoped that this consumma- 
tion will be reached about September, before active mycological 
operations commence. A few copies of the complete work will be 
bound in two volumes, cloth, when finished, but unfortunately the 
number will be much smaller than we could have desired, and 
therefore only prompt application will secure them, before the 
volumes share the fate of their predecessors, by Hr. Hassall, and 
become notified as “ out of print.” 
HESMIDS OF THE UNITED STATES. 
The Rev. F. Wolle has just published a volume on the above 
subject, with 52 plates and descriptive letterpress, at the moderate 
charge of five dollars, which would be equivalent to a British 
guinea. Although we have not yet seen it, there is no doubt of 
both figures and descriptions being fully reliable, and we commend 
it with confidence to the attention of our English readers. A 
large number of the species are also British. The address of the 
author is Bethlehem, Penn., U.S.A.
