It has been inconvenient during the present year to continue 
the work of exploring the Raygill Fissure, on account of the 
quarrying operations in its immediate vicinity. The latter how- 
ever will prove of material assistance in the future work of the 
committee, by enabling them to gain an easier access to the 
Fissure and so reduce the cost of working considerably. A report 
of the work done last year was read at the meeting of the British 
Association at York, and a grant of £20 was made to the commit- 
tee to assist them in the future investigation of the Fissure. 
The council would also express their thanks to W. II. Dalton, 
Esq., of H.M. Geol. Survey, for his kind and valuable assistance 
in the preparation of the Bibliographical lists, which from year to 
year form a very valuable integer in the volume of proceedings.
