viii Edward Alexander Newell Arber . 
establishing the group Primofilices for Ferns characteristic of the Primary 
Rocks. 
In 1907 he published, in conjunction with Major Parkin, an important 
memoir on the Origin of Angiosperms, based on Dr. Wieland s discoveries ; 
this work had the unusual distinction of being translated into German. 
The same authors wrote on the relation of the Angiosperms to the Gnetales 
in 1908. In the same year Arber, in conjunction with Hamshaw Thomas, 
made a valuable contribution to our knowledge of the structure of Sigillaria. 
A sixpenny booklet on Fossil Plants (1909)1*3 worth mentioning for the 
beauty of the photographs, well calculated to interest the lay reader in the 
subject. 
Arber was also an authority on Coal, and published a volume on its 
Natural History in the Cambridge Manuals (1911), which was translated 
into Russian. Among his later works may be mentioned an interesting 
article, for a German encyclopaedia, on ‘ Intermediate Stages between Ferns 
and Seed Plants’ (1913) and a revision of Carboniferous Seed-irnpressions 
(1914). 
When he died so prematurely on June 14, 1918, he left behind 
extensive unpublished manuscripts, including a valuable and original essay 
on the Devonian Floras, now of such urgent interest. 
Arber married in 1909 Miss Agnes Robertson, D.Sc., F.L.S., herself 
a distinguished botanist.
