PROCEEDINGS OF PROVINCIAL SCIENTIFIC SOCIETIES. 
The Annual Report of the Huddersfield Naturalist and Photographie 
Society for 1910-11, besides containing Mr. C. Mosley’s and Mr. A. C, 
Ellis’s general report, includes Mr. E. Fisher’s report on the library, and 
on ornithology, Mr. Mosley’s on lepidoptera, Mr. W. E. L. Wattam’s on 
Botany, and Mr. H. G. Brierley’s on Microscopy. 
A lengthy obituary notice of the late Dr. C. B. Plowright, from the 
pen of Mr. T. Petch, appears in the Transactions of the Norfolk and Norwich 
Naturalists’ Society, Vol. IX., pt. 2. Messrs. Robert Gurney and A. G. 
Innes have valuable papers on The Tides of the River Bure and its 
Tributaries. Mr. J. H. Gurney figures and describes the Norwich Great 
Auk and egg, and Mr. A. B ennett refers to Ginanthe pimpinelloides and 
Epipactis atrovubens. here are also other papers of interest. 
The Leeds Astronomical Scciety has issued its Journal and Transactions 
for r910 (No. 18). They are edited by Mr. E. Hawks, and are sold by 
Messrs. R. Jackson & Son, Commercial Street, Leeds, at 2/-. The contents 
shew that the society has an excellent nucleus of enthusiastic workers, and 
in view of the special nature of the subject, the record is an admirable 
one. We are glad to notice that Mr. Whitmell, in referring to the cause 
of the Glacial P eriod, states that, so far as he knows, “no geologists, and no 
astronomers acquainted with geology, accept Ball’s conclusion that the 
Glacial Period was due to changes in the eccentricity of the earth’s orbit.’ 
The Memoirs and Proceedings of the Manchester Literary and Philo- 
sophical Society (Vol. LV., pt. 2) include many papers of interest to 
naturalists. Amongst them we notice Miss Margaret C. Marsh writes on 
‘Variation in Unio pictorum, U. tumidis and Anodonta cygnea,’ and on 
‘The Ancestry of Trigonia gibbosa, and the ornament of T. clavellata.’ Mr. 
D. M. S. Watson writes on a Plesiosaurian Pectoral Girdle from the Lower 
Lias, Upper Lias Reptilia, and some British Mesozoic Crocodiles. It is 
pleasing to find that attention is being given to this class of fossil-remains, 
but we wish Mr. Watson would give us a little more information with 
regard to the localities from which the specimens were obtained: Mr. 
Holden describes an abnormal spike of Ophioglossum vulgatum. 
The Fortieth Annual Report and Procceedings of the Chester Society 
of Natural Science, etc., contains an interesting contribution to the ornitho- 
logy of the district, entitled ‘ Bird-life in a Suburban Garden,’ The paper 
is by the late Charles Kingsley Siddall, who died last November, in his 
thirty-third year. The report also contains the usual list of additions 
to the museum, etc. We think there is just a little too much matter on 
what would be pages 16-17, if there were room for the page numbers. 
The Society has also issued, separately, a very useful account of “ The 
Formation of the Chester Society of Natural Science, etc.’, and an epitome 
of its subsequent history, by J. D. Siddall. This well illustrated pamphlet 
(64 pp.) is issued ‘ by the desire and at the expense of ’ ten of its members. 
The Transactions of the Natural History Society of Northumberland, 
Durham and Neweastle-upon-Tyne, New Series, Vol. III., Pt. 3, for 1911, 
has been issued, and contains many valuable papers and notes, as well 
as a report on the progress being made at the Society’s museum. The 
Rev. J. E. Hull has a paper on the genus Tmeticus and some allied genera, 
and also on some Northern Spider. Records in 1909. Mr. R. S. Bagnall 
is responsible for three contributions, viz., ‘The British Species of the 
Order Symphyla’; ‘a Synopsis of the British Pauropoda,’ and ‘Two 
New Species of Trichothrips from the Derwent Valley.’ Mr. Stanley 
Smith has a detailed paper dealing with the Faunal Succession of the 
Upper Bernician. There are some shorter notes, amongst which we 
note that the fossil arachnid from Crawcrook, named A nthracosivo latipes 
by Mr. E. L. Gill, turns out to be identical with that previously described 
as A. woodwardi.
