passes through the centre of this Tor running from E. by N. to W. 

 by S. : this direction, and from N.E. to S.W., are the directions of 

 the perpendicular joints. The granite is laminated and coarse with 

 the exception of a bed of very compact crystalline granite running 

 nearly horizontally about 8 feet below the summit of the Tor. On 

 the southern part of the Tor there are 4 perfect and 1 imperfect 

 basins, on the northern part 5 basiQS, and of the last, one is the 

 largest basin that the Author has seen in this district. This basin 

 communicates with the northerly side of the cleft ; in shape it ap- 

 proaches to that of a large caldron, but is not very regular in form ; 

 it measures about 12 feet from N. to S. and 11 feet from E, to W. : 

 the height from the centre of the bottom to the level of the top of 

 the sides is about 5 feet ; the height from a cleft (5 inches wide) at 

 the bottom of the broken southerly side is about 7 feet ; this cleft 

 extends across the basin, and reaches 4 feet beyond its edge in a 

 northerly direction ; and on the easterly and westerly sides hollows 

 open into this basin. Nearly adjoining, there is a large oval hollow 

 measuring about 10 feet from IST. to 8. and 20 feet from E. to W. : 

 at the N.jST.E. the side is broken away, but the average height of 

 the sides above the grass is about 24 inches : the depth to this rock 

 below the turf in the centre is 10 inches : this hollow has not been 

 included in the list of basins, as doubts may be entertained as to its 

 origin. On the hiU to the left of the vaUey that extends from 

 Moreton Hampstead to Bovey there are two basins worthy of note ; 

 one at Ingstone, on account of its size ; the other at Bullaton Rock, 

 as being in a small transported block resting on a large rock. To 

 the north of the Teign, the most remarkable Tors are Wattern, Wild, 

 Belstone, and Yes (2050 feet above sea-level, the highest point of 

 ground in Devon) ; on these no basins exist.

In the following comparison the basins that have not been exa- 

 mined by the Author, imperfect basins, and four that far exceed the 

 average size (viz. at Hell Tor, Kestor, Ingstone, and Bell Tor) are 

 not included. The 35 basins which will be compared are scattered
