Yorkshire Naturalists’ Union: Annual Report, 1914. 47 
Mr. C. T. Trechmann, B.Sc., F.G.S., read a paper on May 
21st, 1914, before the Geological Society of London, entitled 
‘The Scandinavian Drift of the Durham Coast and the General 
Glaciology of South East Durham.” This paper is of: great 
interest to Yorkshire Glacialists. For particulars see The 
Naturalist, July, 1914, page 204. 
At the Whitsuntide Meeting of the Yorkshire Naturalists 
Union held at Filey, there was an interesting discussion as to the 
position of the buried channel which drained the Vale of Pickering 
in pre-glacial times. For particulars see The Naturalist for 
July, page 223. 
Coast EROSION COMMITTEE.—In last year‘s report, Mr. J. T. 
Sewell, J.P., of Whitby, had some interesting notes on the 
erosion of the Coast line between Whitby and Sandsend. 
Mr. Sewell subsequently published a short paper entitled, 
“Coast Erosion at Whitby,’ in The Naturalist for April. This 
paper is illustrated, and contains much additional information. 
Micro-BOTANY AND MIcRO-ZOOLOGY COMMITTEE.—Mr. J. 
W. H. Johnson, B.Sc., F.L.S., writes :—The Section deeply regrets 
to record the death of its Chairman ; his reputation as a pioneer 
in algology is world-wide, and the loss sustained by the whole 
botanical world is indeed great, but it is especially keenly felt 
by this Section. 
At the recent visit of the Union to Sleights, the rare alga 
Vaucheria synandra was identified from the Ruswarp cars, which 
also contains many marine diatoms. Near the road-side at 
Sleights Spirogyra calospora Cleve was obtained, both these are 
I believe, new Yorkshire alga records. 
During the last few years considerable attention has been 
given to the microscopic life in our rivers and streams, especially 
the fungi and alge, Asa result; the following list of additions 
to our local flora has been made, in many cases the organism is 
apparently new to Britain. In the process of identification 
by subculture, higher forms have often occurred and these have 
been included. 
*Zooglea ramigera Itzshn.—River Wharfe at Ilkley; River 
Calder at Cooper Bridge and Balne Beck, Wakefield ; Kirkham- 
merton; besides the type the following varieties have been 
noticed, compacta, carnea and ura. 
Spherotilus natans Kiitz.—Common in most rivers and 
streams and also in warm effluents from trade premises of W. 
Yorkshire. 
Cladothrix dichotoma Cohn.—River Calder, Wakefield, Coxley 
Beck, Balne Beck, Blackburn Brook, Kirkhammerton and 
1915 Jan. 1.
