mens of fossil plants. These enable the general appearance of the plant 
itself to be examined rather than that of a cast or impression, and also 
permit sections to be prepared and examined from fragmentary material. 
New fossil species described by the aid of these methods were shewn in 
illustration. 
Committee of Suggestions for Research .—Peat Investigation Work : 
Maps showing the Distribution of the Remains of Early Man on the 
Southern Pennines. Flints of the Pennine Moors and their relation to 
the Peat of S. W. Yorkshire : (1 ) Pennine Peat, by C. A. Cheetham 
and W. H. Burrell, exhibits illustrating a study of upland peat during 
recent years showing that — (i.) Pan formation preceded accumulation of 
deep moor peat; (ii.) Juncus communis L. entered largely into the 
composition of the early vegetation ; (iii . ) Eriophorum vaginatum L. is 
the plant of outstanding importance in peat formation. Photographs 
of the organisms commonly found in peat were exhibited. An interesting 
feature of many peat samples is the presence of the recently identified 
spermatophores of the Copepod. (2) Studies in the Distribution of the 
Primitive Pennine Forest, by Dr. T. W. Woodhead. This exhibit 
consists of specimens of tree remains found beneath the peat on the 
Southern Pennines in the District of Huddersfield. (3 ) Diagrams illus- 
trating the Effect of Topography on Peat Formation and Woodland 
Destruction, by Dr. W. H. Pearsall. (4) The Physiological Anatomy of 
Plants growing upon Peat, by Prof. Priestley and Miss Mildred Hinchliff I 
Microscopic slides of typical plants from a Yorkshire peat moor, showing 
that these plants are characterised by excessive deposits of fat in their 
tissues, with consequent effects upon their structure (see The Naturalist 
for September, 1922). 
An important supplementary exhibit was a fairly complete collection 
of the Publications of the Union, including a long run of The Naturalist, 
the Transactions, Excursion Circulars and Secretaries’ Reports. With 
the Transactions were shown such important monographs as Baker’s 
‘ North Yorkshire ’ and Lee’s ‘ West Yorkshire.’

The Local Programme of the British Association at Hull, 
1922 . 72 pages, with map, 11 plates and various illustrations. 
Sold by A. Brown & Sons, Limited, Hull. Price is. 3d. post free. 
This is distinctly the best and most useful programme of its kind we have 
seen for a long time, and reflects the greatest credit on its Authors and 
Editor. Nearly half of it is taken up with an admirable account of the 
Yorkshire Naturalists’ Union and its Work, in the course of which, what 
has been done, and is being done, by the various Sections, and. all the 
large number of Committees is so clearly set forth, that the members of 
the British Association could not fail to grasp, from the enormous amount 
of original investigation which has been achieved in the county by so 
many members of the Union, and which was evidenced by the fine 
exhibition illustrating almost every phase of the Union’s work — the 
immense share it has had in the scientific work and thought of our county. 
This indeed was admitted by many of the members of the Association. 
The other portion of the Programme contains a clearly defined plan 
of the meeting rooms in the Guildhall, followed by full particulars as to 
all the Meetings, Excursions, Papers to be read, complete lists of all the 
members of the various Committees ; time tables of the trains to the 
near outside towns, with the fares ; with local information on every 
minute point one can conceive as likely to be of use to visitors to make 
for their convenience and comfort. Cast, but not least, there are photo- 
graphs of the Officers of the British Association, and all the local officers 
connected with the meeting, which, if all are as good as that of the 
Editor, will add largely to the interest of the Programme as a Souvenir 
of the Hull Meeting. It is sold by A. Brown Sc Sons, Ltd., Hull, price 
is., postage 3d. — G.T.P.
