in the locality as Helstone. It is 230 feet above sea (ordnance datum), 

 and marks a boundary on the farm ; all land on the farm east of the 

 stone is called Ost-end, and all west West-end. It lies amongst lower 

 glacial " drift-clay," and is quite isolated. It was thought by many per- 

 sons to be the rock in situ. It rests upon worn surface of Rhaetic beds. 

 It is to be removed to the grounds of the Leicester Museum, and photo- 

 graph taken before removal. 



Another large isolated boulder is situated at Loseby, Leicestershire, 

 on the estate of Sir F. T. Fowke, Bart., Loseby Hall, Leicestershire. It 

 measures 5 feet 3 inches X 3 feet 5 inches X 2 feet 4 inches. It is 

 rounded and worn, is long shaped, has never been moved by man, and has 

 small groovings at various angles on all the sides exposed. It is composed 

 of millstone grit, which occurs 35 to 40 miles N.W., but it may have 

 travelled 80 miles if it came from the north. It is 650 feet (ordnance 

 datum) above the sea; and rests in "upper glacial drift," composed of 

 sand, flints, chalk, has, sandstone, millstone grit and pebbles of various 

 sorts, and lumps of clay. 



(2.) Oroups of Boulders. 



The first group recently found in the " Coleman Road " (a new road 

 about two miles from here) is quite a new district for boulders. The group 

 occurs in Bvington parish, near Leicester ; the road is about two miles 

 long, in a "cutting" through "Crown Hill." The largest boulders 

 are 3 feet 3 inches x 3 feet x 2 feet 6 inches ; the smallest 1 foot 3 inches 

 X 1 foot x 1 foot. They are angular and sub-angular, except the block of 

 "limestone," which seems rounded, but it may have been done in situ. 

 All have been moved in excavating the road, and many broken up. 

 Most of the sandstones, grits, and limestones, have striations in various 

 directions on the top and sides, and at different angles. The localities at 

 which rocks of the same nature as the boulders occur are — Mount Sorrel, 

 Groby, and Markfield. east side of " Pennine Chain," in valley of River 

 Derwent, and Stanton, valley of the Erewash, Sherwood Forest, country 

 round Nottingham, Ticknall, Crick Hill, Wirksworth, Derbyshire. The 

 distances of these localities are as follows : — 



Miles. 



Mount Sorrel 8 N.N.W. 



' Groby 8 N.W. 



Markfield 10 N.W. 



Stanton 22 N.W. 



Erewash 24 N.W. 



Derwent 35 and 40 N.W. 



Sherwood and Nottingham 24 N.N.W. 



Ticknall 20 N.W. 



Crick and Wirksworth 40 N.W. 



Sixteen blocks were measured and examined ; 7 of these were syenite and 

 syenitic granite, 5 triassic sandstones, 2 millstone grit, and 2 mountain 

 limestone. A great many of the limestones, grits, and sandstones have 

 been broken up for road metal, being softer than the syenites. The group 

 is about 350 feet above the sea. The area covered is about 50 yards long 

 by 10 yards wide. A few boulders occur in other parts of the road, but 

 of smaller dimensions ; many boulders are left in the sides of the cutting, 

 and every indication seems to be that great numbers spread out in the
