366 " REPORT—1896. 
Erratic Blocks of the British Isles—First Report of the Committee, 
consisting of Professor EH. Hunt (Chairman), Professor T. G. 
Bonney, Mr. P. F. Kenpauu (Secretary), Mr. C. E. DE Rance, 
Professor W. J. SoLuas, Mr. R. H. Trppeman, Rey. S. N. Har- 
RISON, Mr. J. Horne, and Mr. DuGatp BELL. (Drawn up by the 
Secretary.) 
Tue Committee were reconstituted at the Ipswich meeting of the Asso- 
ciation, so that the erratics of the whole of the British Isles now come 
within their purview. The Scottish Corresponding Societies have heen 
invited to aid in devising a scheme of organisation by which the desired 
end—the collection of significant facts regarding the distribution of ice- 
borne blocks—may most speedily and with the least waste of power be 
attained. Several Societies have made a favourable response, and it is 
hoped that before the presentation of the next report a considerable body 
of evidence will have been collected. 
In England the work of organisation has been advanced a notable way 
by the formation of a boulder committee by the Lincolnshire Naturalists’ 
Union on similar lines to that which has done, and is doing, such valuable 
systematic work in Yorkshire. The Rev. W. Tuckwell has accepted the 
secretaryship of the new organisation, and his well-known energy and 
enthusiasm are guarantees that the work will be carried on persistently 
and thoroughly. The proximity of the active sub-committee working in 
the East Riding of Yorkshire has been a great advantage to the Lincoln- 
shire Committee, who have had the advantage of the advice and active 
co-operation in the field of several experienced boulder hunters from 
Yorkshire. 
Mr. Tuckwell’s first report records 102 boulders. These include many 
examples of characteristic Scandinavian rocks, such as the well-known 
Augite-syenite and Rhomb-porphyry. One example of the former rock, 
observed near Louth, is the largest specimen yet found in England, and it 
is satisfactory to learn that Mr. Tuckwell has taken effective measures for 
its preservation. Another notable record is that of three specimens of 
Shap granite, the first recorded in Lincolnshire, one of which was found 
imbedded in undisturbed glacial deposits at South Ferriby, while another 
was found built into a tenth-century Saxon wall at Irby. 
The Yorkshire Boulder Committee have again done most excellent 
work, the value of which is enhanced by care displayed by the secretary, 
Mr. Tate, to investigate personally all boulders of more common interest 
or novelty, and by the petrological knowledge which he brings to the 
work. 
The reports sent in from the East Riding are an enumeration of no 
fewer than 2,600 boulders, and complete an exhaustive catalogue of all 
the boulders at present visible in the cliffs or on the beach along the whole 
coast-line of Holderness from Spurn Point to Bridlington, a distance of 
36 miles. Among these were many examples of Augite-syenite and 
Rhomb-porphyry. 
A report by Messrs. Herbert Muff and Thomas Sheppard brings out 
the extraordinary prevalence of boulders of Shap granite at Robin 
Hood’s Bay where no fewer than 81, varying from a few inches up to
