Northern News. eve: 
district, this species was not known to exist here. It is not 
included in his list, and having had the advantage of examining 
many hundreds of his slides, Iam able to say that I have not 
found it in any of his East Riding gatherings. Notwithstanding, 
it is a common and widely distributed species. I have found it 
in Switzerland, Italy, Scotland, North of Ireland, Wales, and 
the English Lake District, as well as in many places in the 
north and west Ridings of Yorkshire (Y.N.U. excursions to 
Sedburgh, Bowes, Hebden Bridge, Buckden, Ilkley, Farnley 
Tyas, etc.). A gathering I took from Weedley Springs, in the 
spring of 1897, shows no trace of it, and its first appearance in 
the East Riding to my knowledge was in Sept., 1899, when I 
found it plentifully in Newbald Springs. Since then I have 
found it in Weedley Springs, in Stream Dyke, Hornsea 
Mere, and in flooded fields after heavy rains off Beverley Road 
and Sculcoates Lane. In the last year or two it seems to have 
increased enormously. At the Pocklington excursion it was 
plentiful in the Great Givendale Springs, and also last year at 
Weedley. This year it appears to have ousted almost every- 
thing else from Weedley Springs. It will be interesting to see 
if anything of the kind has occurred in other Wold Springs, 
and also to frame a theory to account for the rapid and success- 
ful invasion. The species is somewhat variable, and in addition 
to the drawing of the form found at Weedley, I have drawn two 
others, the longest, with 10 to 14 coste, being found in the 
Sertigthal, an Alpine Valley near Davos, and the shortest, with 
only 3 or 4 costez (variety mesodon), coming from a mountain 
torrent at Chiavenna, North Italy. Our English forms are 
chiefly intermediate, but nearer to the latter.

From July 8th to July 12th the Museums Association visited Dundee. The 
following Northern museums were represented :—Bootle, Sheffield, Bolton, 
Stoke-upon-Trent, Burnley, Newcastle, Stockport, Carlisle, Manchester, St. 
Helens, Warrington, Bolton, Huddersfield, York, Hull. Amongst the many 
papers read and discussed, the following were of particular interest and 
value :—‘ Methods of Collecting and Exhibiting English Pottery and 
Porcelain ;’ ‘ Methods of Utilising Wall Spaces ;’ ‘ Notes on the Attitude of 
Birds ;’ ‘Centralising Museum Work;’ ‘Museums of Industrial Art ;’ 
‘Museums in Higher Grade and Secondary Schools ;’ ‘Circulating School 
Museums ;’ ‘ Museums Illustrating Town History ;’ ‘The Sunday Opening 
of Museums ;’ ‘ Civic Museums ;’ and ‘An improved Method of Exhibiting 
Coins.’ An exceedingly valuable feature of this Conference was the 
opportunity afforded of examining famous collections of furniture, china, &c., 
which exist in the district. Amongst the places visited in this way were ;— 
Rossie Priory, the seat of Lord Kinnaird ; the University College, Dundee ; 
the Perth Museum ; Glamis Castle, the seat of the Earl of Strathmore ; and 
The University Museum, Castle, and Marine Laboratory at St. Andrews.
