2. Geological Survey of Western Australia. A. Gibb Matt- 

 lakd, Government Geologist. — The following bulletins have 

 recently been issued by this organization : 



Bulletin No. 27. Palaeontological Contributions to the Geology 

 of Western Australia ; by R. Etheridge, F. Chapman, and W. 

 Howchin. 



Bulletin No. 28. The Geology and Mineral Resources of Law- 

 lers, Sir Samuel, and Darlot (East Murchison Goldfield), Mount 

 Ida (North Coolgardie Goldfield), and a portion of the Mount 

 Margaret Goldfield ; by Chas. G. Gibson", Assistant Geologist; 

 68 pp., with 3 maps and 5 mining plans. Perth, 1907. — The 

 rocks in the district including these mines are granites and 

 greenstones, the former intrusive in the latter. Quartz veins of 

 still later origin cut both rocks. The bulletin is chiefly con- 

 cerned with detailed descriptions of the occurrence of the ores 

 and of the mining operations. 



Bulletin No. 30. The Distribution and Occurrence of the 

 Baser Metals in Western Australia ; by Edward S. Simpson and 

 Chas. G. Gibson. 117 pp., with map. Perth, 1907. — The method 

 of exploitation and the history of mining of copper, tin, lead, 

 zinc, iron, manganese, tantalite, aluminium, antimony, bismuth, 

 cobalt, tungsten, and molybdenum are discussed in detail. The 

 iron deposits of Western Australia are "probably some of the 

 largest in the world" but have remained undeveloped owing to 

 their location and the absence of coal. 



The bulletins issued by the Survey of Western Australia are 

 necessarily of economic nature, and although the ore deposits are 

 described in great detail the publications do not serve to explain 

 the geology of the region as a whole. This defect has been 

 remedied in part by the admirable address of A. Gibb Maitland, 

 Government Geologist, on the Recent Advances in the Knowl- 

 edge of the Geology of Western Australia. This address is 

 accompanied by a geological map. h. e. g.
