gardens were established. We earnestly hope that Professor 
Compton’s requirements will be fully met when the Government 
Commission on the lay-out, development and functions of the 
Gardens has considered the matter. 
It is pleasing to note that the offer of the later Mr. J. D 
Logan of a piece of land near Matjesfontein for the establishment 
of a garden of Karroo plants under Karroo conditions has been 
confirmed by his heirs. 
The Marine Algae of the Danish West Indies.—The interest 
of the Danes in the study of natural history, not only in that 
of their own country, but of the distant parts of their kingdom, 
is strikingly shown in the remarkable series of memoirs on the 
Botany of the Faeroe Islands and the Botany of Iceland. The 
same spirit is apparent in the various publications by Dr. F. 
Bergensen on the marine algae of the Danish West Indies. His 
largest work on the algal flora of these Islands,* the final part of 
which has now been issued, is by far the most elaborate of any 
work, which contains the descriptions of many new species and 
innumerable critical notes, is marked throughout with extreme 
care and thoroughness. A special feature is the very large 
number of illustrations. 
Although the islands in question have now passed to America 
(the Danish flag, after waving for over 250 years, being lowered 
in 1917), ‘“‘ The Marine Algae of the Danish West Indies ”’ will for 
all time be found a standard treatise for students of the marine 
flora of the entire region. a0°Do0

years we are glad to welcome another part of Mr. Dut 
Flora. The families from Coniferae to Juncaceae are dealt with 
in 114 pages, full English descriptions being given of each plant 
treated of and artificial keys where necessary to the genera and 
species. Nearly half of this part is devoted to the Orchidaceae, of 
which 59 species occur in the area. Otherimportant contributions 
are the account of the Agaves arranged according to the paper 
by Drummond and Prain (Agricultural Ledger, xiii. 78) and of 
the Dioscoreas reins on Prain and Burkill’s Synopsis (Journ.
