Report of the Committee, co)islstl)ig of Professors A. H. Green and 

 L. C. .AIiALL and ]\Iessrs. John BiucHr and James W. Davis 

 {Secretary), appointed to assist in the Exp tor at Ion of the Llayijill 

 Fissure in Lothersdale, Yorkshire. 



During the past year operations have been entirely suspended, to 

 -enable the proprietors of the quarry in which the fissure is situated to 

 remove, by quarrying, a large mass of limestone, which greatly interfered 

 with the work of excavation by your Committee. The removal of this 

 limestone is now nearly completed, and it is hoped that in two or three 

 months the examination of the fissure may be resumed. The importance 

 of the work was sufficiently demonstrated in the report of last year, and 

 your Committee suggest that the grant of 15Z. should be renewed and 

 increased to 20/. They wish to express their sense of the kindness of the 

 proprietors, Messrs. Spencer, who have, at considerable cost and no small 

 inconvenience, greatly facilitated the work of the Committee, besides 

 iredncing the cost of its future explorations.
