Twelfth Report of the Committee, consisting of Professors J. Prest- 

 wich, W. Boyd Dawkins, T. McK. Hughes, and T. Gr. Bonney, 

 Dr. H. W. Crosskey (Secretary), Dr. Deane, and Messrs. C. E. 



DE RANCE, H. Gr. FORDHAM, J. E. LEE, D. MACKINTOSH, W. 



Pengelly, J. Plant, and E. H. Tiddeman, appointed for the 

 purpose of recording the position, height above the sea, litho- 

 logical characters, size, and origin of the Erratic Blocks of 

 England, Wales, and Ireland, reporting other matters of in- 

 terest connected with the same, and taking measures for their 

 preservation. 



This Committee is continuing its researches into the distribution, 

 position, and general characteristics of the Erratic Blocks of England, 

 Wales, and Ireland, and is preparing a connected account of the general 

 results obtained, which it hopes to be able to submit at an early 

 meeting of the Association. 



Meanwhile, the following details respecting newly observed erratic 

 blocks are recorded. 



Essex : Newport. — Mr. George Linney, of Saffron Walden, has furnished 

 an account of a large erratic now standing on the high road from 

 Cambridge to Bishop's Stortford, about 225 yards south of the entrance 

 to the Sholgrove demesne, on the side nearest to Newport, and about a 

 mile from Audley End station. 



The dimensions above ground are, height 6 ft. ; width, at top 3 ft. 

 6 in., at base 6 ft. ; thickness 2 ft. 



The general shape is irregular, but the sides are nearly flat. Height 

 above the sea-level about 180 ft. 



It is composed of millstone grit. This boulder has no local history, 

 except that a vague tradition exists that it was placed in its present posi- 

 tion as a mark for a Lepers' Hospital, which was done away with by 

 Henry VIII. 



Warwickshire. — Mr. Fred. Martin has drawn up the subjoined account 

 of erratic blocks which have been exposed during the process of 

 enlarging the West Suburban Railway, which runs from New Street, 

 Birmingham, through Edgbaston to King's Norton, a distance of about 

 5£ miles.
