In Memoriam : William West, F.L.S. 
always fully conscious of the importance of the common and 
dominant forms, ever alive to the significance of every obser- 
vation he made. 
The algological investigations which were now his and 
his son’s chief line of research, were most diligently and system- 
atically prosecuted. Holidays were all utilized for the accum- 
ulation. of material, many parts of the British Isles being 
visited, especially the montane regions of Scotland and Ireland, 
North Wales and the English Lake country. 
The work began near home. Their native county of York 
was fully worked, lists being published for each of the three 
Ridings, and finally in 1900-1901 a complete Alga-Flora of the 
whole county. 
Then came papers dealing with the English Lake District 
{1892), the South of England (1897), Xorth Wales (1890), 
Scotland (1893), the Orkneys and Shetlands (1905), the West 
of Ireland (1892), the North of Ireland (1902). and the Clare 
Island Survey (1912), 
European countries were left to continental workers, except 
that papers were published concerning Denmark (1891) and 
Portugal (1892). 
.Material was now being sent to them from all over the 
world, and papers were published for the American States of 
Maine (1888, 1891). ancl Massachusetts (1889), and for the 
West Indies (1894, 1899). 
For the Old World were published memoirs dealing with 
Singapore (1897), Koh Chang (1901), Ceylon (1902), Burma 
and other parts of India (1907), and Kinabalu and North 
Borneo (1914) ; and meanwhile another able Leeds algologist, 
.Mr. W. Barwell Turner, had monographed the Indian Desmids. 
Madagascar was dealt with by the Wests in 1895, Central 
Africa in 1896. and Welwitsch’s African collections in 1897 ; 
and in 1911 the freshwater algae collected by the Shackleton 
Antarctic Expedition. 
All these were in addition to numerous notes in various 
journals, and articles of more general scope and import, such 
as on the Conjugation of the Zygnemaceae (1891), and Obser- 
vations on the Conjugal ae (Annals of Botany, 1898). 
Of late years much of the purely algological work fell 
to the vounger West, while the elder devoted much time to 
.Mosses and especially Lichens and also to ecological observa- 
tions on br3’ophytes and Lichens. ; - 
Finally came the publication by the Ray Society of the 
culminating work — the ‘ Monograph of the British Desmidi 
actae ’ — of which four volumes have appeared (1904, 1905. 
1908, 19x1) and the remaining two still remain to be finished 
by the surviving author.
