3. " The Igneous Constituents of the Triassic Breccias and Con- 

 glomerates of South Devon." By R. N. Worth, Esq., F.G.S. 



During the investigation several hundred fragments were exa- 

 mined, the largest occurring at Teignmouth, between which place 

 and Dawlish the breccias are most varied in composition, and con- 

 tained the greatest proportion of granitoid rocks. The igneous 

 fragments were thus divided: — I. Granites; II. Felsite group: a, non- 

 schorlaceous, b, schorlaceous ; III. Andesitic group : IV. Miscella- 

 neous. Of these, including in all 76 varieties, I., II. b, and IV. are 

 plainly of Dartmoor origin in gross, the schorlaceous and contact- 

 altered rocks having belonged to the outer or to an upper zone ; 

 III. can for the most part be identified with the in-situ " felspathic 

 traps" of the neighbourhood. The non-schorlaceous division of II. 

 differs but little from Dartmoor elvans ; some may have been surface- 

 portions of felsitic dykes, or even fragments of felsitic lavas. The 

 igneous fragments of the breccias, as a rule, are not much altered 

 structurally ; they are of local origin. 



The large blocks indicate the vicinity of high land abutting on a 

 shore-line. Of this high land Dartmoor is a relic. The transporting 

 power of water was perhaps supplemented by a glacial climate and 

 volcanic activity. De la Beche considered that igneous action 

 accompanied the earliest " red-rock " deposits. The " felspathic 

 traps " are known to be both antecedent to and contemporaneous 

 with the breccias, and there is evidence which points to their being 

 comprised within the period of igneous activity represented by the 

 Dartmoor elvans. The author says that there is a preponderance of 

 volcanic over plutonic igneous rocks, and thinks that the existing 

 remnants of " felspathic traps " are not sufficient to supply the 

 quantity. He suggests that they must have come from an upper 

 portion of Dartmoor. 



In conclusion, the author considered that he has shown that the 

 igneous materials are of local origin, and that they consist of granites, 

 felsites, and volcanic types, ranging from andesites to basalts ; that 

 the few igneous fragments not hitherto assigned to in-situ rocks are 

 yet of a similar character ; that the conditions under which the 

 "felspathic traps" occur in situ lead to the inference that they are 

 volcanic phenomena which probably represent the final phase of 

 the igneous activity of the Dartmoor region. Lastly, he expresses 

 his opinion that the elevation of Dartmoor and the associated igneous 

 phenomena took place at a period not earlier than the Permian. 



4. " Notes on the Glaciation of Parts of the Valleys of the Jhelam 

 and Sind Rivers in the Himalaya Mountains of Kashmir." By 

 Capt. A. W. Stifle, F.G.S. 



After referring to the previous writings of Messrs. Lydekker, 

 Theobald, and Wynne, and Col. Godwin-Austen, the author gave an 

 account of his observations made during a visit to Kashmir in 1885,
