observed by myself, and such is the stress laid on this that, although 

 Dr. Verbeek kindly suggests a sharp anticline as an explanation, I felt, 

 on reading the passage, misgivings as to the accuracy of my own 

 statement. I have to-day re-examined the hill, and find that the 

 section is more luminous than in 1906. IS'ot only has much of the 

 base been removed, exposing fi'esh rock, but a deep cutting has been 

 made through the hill, cutting about jS'.N.W.-S.S.E., that is, parallel 

 to the strike of the beds. The place where I observed the dip in 1906 

 was recognizable, and my observation was correct. The general dip 

 is to the W.S.W., and this obtains at both ends of the cutting. There 

 is, however, some evidence in the section (about 150 feet long) of 

 apparentlj" local but sharp folding and of faulting, such as is frequently 

 seen in a disturbed area, but not of a distinct anticline affecting any 

 considerable portion of the section. As a result of these folds and 

 faults there are local dips to the E.N.E. in four places, while in four 

 places the beds are vertical. The small quarry mentioned by 

 Dr. Verbeek on the south side of the hill, which, but for the cutting, 

 is now covered with grass, doubtless showed a local variation of dip. 

 The matter seems to me to be of no great importance and not worth 

 a figure of the section, but this explanation is due as much to 

 Dr. Verbeek as to myself.

CULM INCLUSION IN COARSE GRANITE. 



Sir, — Although sedimentary inclusions in the granites of the 

 Western Counties have often been described, the following occurrence 

 may be worth a note. In the course of a walk from Lustleigh station 

 to Foxwortby Mrs. Hunt called my attention to a fragment of rock 

 protruding from a mass of granite lying by the roadside for road- 

 metal. The roadmen then were clearing rocks in a neighbouring 

 field, distant about two -thirds of a mile from the nearest granite 

 boundary. The enclosing granite was of very coarse matrix with 

 large orthoclases. The inclusion was a rhomboidal fragment of what 

 seemed to have been a culm grit with planes of sedimentation, and 

 with ordinary surfaces of fracture in the usual joint planes ; weight 

 about 1-J-lb. The points of interest are that, though the fragment 

 is completely crystallized, the boundaries are not dissolved or distorted. 

 Before this very coarse enclosing granite was consolidated the 

 fracture of the culm rocks was much as it is at present. Dr. Flett 

 kindly confirmed my recognition of the . fragment as sedimentary. 

 Having seen much granite broken in the neighbourhood during the 

 past twenty-five years for building and road-making, this particular 

 specimen is unique of its kind in my experience. I have since 

 noticed a triangular fragment in the same lieap of stones, which 

 I mav possibly succeed in getting hold of.
