ON TJIE ERRATIC BLOCKS OF ENGLANO, WALES, AND IRELAND. Ill 



1. One at Lees Sfci-eet, Piccadilly, Mauchester, measuring 4 ft. 4 in. 

 X 4 ft. X 3 ft. 



2. One at Unnstoai, in the parish of Urniston, five miles west of Man- 

 fhcstei'. 



3. One at Elixton, in the parish of the same name, seven and a half 

 miles west of Manchester. 



This measures 3 ft. x 2 ft. 8 in. x 2 ft. 1 in., but has been broken, 

 mid is said to have been originally half as large again. 



All three are subangular ; (1) and (2) are quadrilateral ; (3) is some- 

 what conical. 



They have numerous groovings and striations, although none are very 

 deep, upon the flat sides. 



The striations of (2) are diagonal at about 45° ; and of (3) in a line 

 with the longest axis. 



The whole of these boulders, together with two others of lesser dimen- 

 sions, consist of very fine highly siliceous grit rock, particularly (1) and 

 ( 2), which almost become quartzites. They are all of a hght bluish, fawny 

 colour, (1) being of the darkest hue ; are all compact, and do not exhibit 

 any trace of lamination or bedding. 



These boulders, together with the large one at Old TrafFord, were 

 found in almost one line, viz., roughly, E. and W. 



^0 locality of deiivation has yet been assigned to them. 



They were disinterred from the di-ift, and are at the height of about 

 120 feet above the sea. 



(1) is deposited in Alexandra Park, Manchester. 



(2) is in a farm-yard at Urmston. 



(3) is on the Red Lion bowling-green, Flixton. 



Leicestershire. — The Committee are indebted to Mr. J. Plant for the

 observations which have been recorded in previous Reports. 



Isolated Boulders. 



Boulder at Aylestone, near the river Soar, two iniles from Leicester. — 

 Dimensions 4 ft. X 3 ft. 6 in. x 3 ft. It is subangular ; the direction of the 

 longest axis is N.E. by S.W., and it is without striations. It is com- 

 posed of .syenite, similar to that of Markfield, seven miles distant to 

 the x^.W., and there is no rock like it in the immediate locality. Long 

 ridges of sandy gravel running S.E. occur near it, nnd it rests on sandy 

 gravel. 



Another boulder composed of the same rock occurs in the same 

 locality. Dimensions, 3 ft. 10 in. x 2 ft. 10 in. x 2 ft. 6 in. It is also sub- 

 angular, with the same direction of its longer axis, and without striations. 

 It is 200 feet above the sea-level, and is situated at the If. end of long 

 ridges of hand, which appear to be the debris of Upper Keuper Sandstone. 

 It rests upon sand. 



Boulderiu.the village of Thurnhy. — Dimensions, 4 x 3 x Ifoot. Rounded 

 and without striations. It is composed of granite similar to tliat of 

 Mount Sorrel, eight miles distant to the N.W., and there is no I'ock like 

 it in the immediate locality. It is about 600 feet above the sea-level, and 

 rests on coarse gravel. 



Another boulder of the same character occurs in a field near the same
