VIII. — Bkief Notices. 



1. Pebmo-Caiibonifee,ous Ice Age ik Western Atjstealia. — This 

 subject was dealt with by Mr. A. Gribb Maitland in his Anniversary- 

 Address to tbe Natural History and Science Society of Western 

 Australia (vol. iv, session 1910-11). The essay is well illustrated 

 by map, sections, and photograpbic views. 



2. Geological Sdrvey of South Australia. — In Bulletin No. 2 

 (1913), the Government Geologist, Mr. L, Keith Ward, discusses the 

 possibilities of tbe discovery of petroleum on Kangaroo Island and 

 the western coast of Eyre's Peninsula, and comes to the conclusion 

 that the facts do not justify the expenditure of capital in boring 

 for oil. Some account is given of the rubber-like material known as 

 ' coorongite ', but there appears to be no genetic connexion between 

 it and petroleum. 



3. Mining in South Australia. — The Review of Mining Operations 

 in the State during the half-year ended December 31, 1912 (No. 17, 

 1913), gives satisfactory accounts of the production of copper, gold, 

 and silver; other minerals obtained include lead and iron ores, 

 uranium ores, gypsum, and graphite. 



4. Indian Aerolites. — G. de P. Cotter, B.A., contributes "Notes 

 on Indian Aerolites recorded since 1906" (Rec. Geol. Surv. India, 

 vol. xlii, pt. iv, p. 265). The paper gives details of six falls, viz., 

 Yishnupur, Chainpur, Mirzapur, Baroti, Khohar, and Lakangaon. It 

 is admirably illustrated by fourteen photographs of separate stones, 

 and by a map of the Chainpur fall. The mineral constitution of the 

 stones is only discussed very briefly. 



5. The Bernese Jura. — Tbe structure of the Bernese Jura finds 

 an able expositor in Dr. P. Schlee, who in an interesting paper 

 published in the Mitth. geogr. Gesellsch. Hamburg, xxvii, 1913, 

 illustrates his remarks with a fine series of photographic reproductions, 

 a map, and sections. The paper can be obtained separately from 

 Friederichsen & Co., Hamburg, for 3 marks, 



6. Termites and Geology. — Mr. Donald Steel writes in the 

 American Naturalist, July, 1913, on this subject. He does little 

 more than record the facts, but we gather from a perusal of his paper 

 that the woi'k of the Termites is much like that of worms, a turning 

 over the surface soil. The Termite, however, piles the soil up into 

 hillocks, which are themselves worn down again by storms, and 

 gradually spread over the surrounding country. 



7. The Landes of Gascogny. — M. Edouard Harle (Bull. Soc. geol. 

 France (4), xii, 1912) has investigated the Landes of Gascogny, and 

 comes to the conclusion that far from being extremely old and 

 entitled to the term ' Peneplaine landaise ' of authors, these tracts 

 are qu'ite modern and still in process of formation. They are due to 

 the prevalent westerly winds, are of difi'erent ages, and continually 

 changing. In the same communication Harle traces the changes in 

 the bed of the lliver Adour, the struggle between that river and the 

 dunes, and their influences on each other.
