Devon in the neighbourhood of Salcombe estuary. In the first part 

 of the paper details were given of the sections exposed around tho 

 estuary, at Hope Cave to the westward, and in several localities to- 

 the eastward as far as Hall Sands, all confirmative of Professor 

 Bonney's views, and showing that the slaty beds to the northward 

 do not pass into the mica and chlorite schists to the south, but are 

 separated from the latter by a line of faults. 



Descriptions were then given of microscopic slides from various 

 parts of the metamorphic rocks. Some of these showed the action 

 of secondary forces. The effects of lateral pressure in producing 

 cleavage-planes and a kind of jointing were also commented upon. 



An attempt was also made to determine the succession of chlorite- 

 mica- and micaceo-chloritic schists around Salcombe estuary. The 

 beds appeared to succeed each other in the following order, com- 

 mencing from the northward : — 



1. (a) Interbanded series south of Halwell Wood, etc. 



(h) A thick band of chlorite-schist at Scoble, Snapes Point, etc. 



2. (a) Mica-schist north of the side estuary. 



(&) Interbanded series south of the side estuary. 



3. Mica-schist of Portlemouth Ferry. 



4. Chlorite-schist of Bickerton. 



3. " On the Ancient Beach and Boulders near Braunton and 

 Croyde in North Devon." By Prof T. McKenny Hughes, M.A.^ 

 F.G.S. 



The author observes that amongst the raised beaches of S.W. 

 England we generally find included the sand cliffs of Saunton Down, 

 and Middleborough on the coast west of Barnstaple. These de- 

 posits possess a further interest owing to the occurrence at their 

 base of large boulders. In 1866 Mr. Spence Bate, in opposition to- 

 the prevailing view, concluded that the so-called raised beach is the 

 undestroyed remnant of an extensive district of wind-borne sand 

 similar to that which now exists on Braunton Burrows. The points 

 to which attention was invited are as follows : — 



1. Is this deposit on the southern slope of Saunton Down a 

 raised beach ? 



2. Were the above-mentioned boulders carried to their present 

 position by ice ? 



The paper was fully illustrated by diagrams, showing the relations 

 of the recent deposit, and by figures showing the mode of occurrence 

 of three of the most remarkable boulders. The conclusions were : — 

 (1) That the ancient beach of Saunton Down and Croyde is not a 

 raised beach in the ordinary acceptation of the term. The top is 

 subaerial talus, the middle part is blown sand, the base only marine, 

 and the marine part is not above the reach of the waves of the sea 

 at its present level. (2) The boulders of granite and felsite which 

 occur at the base of the ancient beach were transported to their 

 present position by the waves of the sea. Such as are of local 

 origin could have reached the sea by the ordinary processes of de- 

 nudation ; such as are possibly of northern origin could have beeu
