Fifth Report of the Committee, consisting of Professor Prestwich, 

 Prof. Harkness, Prof. Hughes, Prof. W. Boyd Dawkins, the 

 Rev. II. W. Crosskey, Messrs. L. C. Miall, Ct. H. Morton, D. 

 Mackintosh, R. H. Tiddeman, J. E. Lee, T. Plant, W. Pex- 

 gelly, and Dr. Deane, appointed for the purpose of recording the 

 position, height above the sea, lithological characters, size, and 

 origin of the Erratic Blocks of England, Wales, and Ireland, report- 

 ing other matters of interest connected icith Ihe same, and taking 

 measures for their preservation. Drawn up by the Rev. II. AY. 

 Crosskey, Secretary. 



The Committee during the past year has continued to pursue the method 

 described in previous Reports. The schedule printed in the British Asso- 

 ciation Report for 1873 (p. 189) has been circulated, and replies of con- 

 siderable interest have been received. The problems involved are so vast 

 (covering as they do the whole history of the glacial epoch), and the facts 

 are as yet so imperfectly recorded, while the destruction of erratic blocks is 

 going on throughout the country -with such rapidity, that the work of the 

 Committee increases in importance.
