3. Geological Survey of Western Australia. Bulletin No. 32, 

 pp. 91, with 3 maps and 7 plates ; by Harry P. Woodward, 

 Assistant Government Geologist. Perth, 1908. — This recent pub- 

 lication contains an account of the GreenbushesTinfield; of theMt. 

 Malcolm copper mine, Eulaminna ; of Fraser's gold mine, Yilgarn 

 gold field. The primary tin deposits occur in crystalline granite 

 rocks, which lie within a belt of greenstone and greenstone 

 schists ; there are also secondary alluvial deposits. The amount 

 mined in 1906 was 783 tons and in 1907, 770 tons. Various rare 

 minerals occur with the tin ore, including tantalite, stibiotanta- 

 lite, microlite, gahnite, etc. It is noted, also, that particles of 

 undoubted metallic tin have been found, but it is suggested that 

 they may owe their origin to the action of bush fires on surface 

 exposures of tin ore. 



4. New Zealand Geological Survey Department. Second 

 Annual Report (New Series), Wellington, 1908. Pp. 39, 8 plates, 

 2 maps. — This report gives a concise summary of the operations 

 of the New Zealand Geological Survey between January 1, 1907, 

 and May 31, 1908. It deals in part with the topography, in part 

 with the geology, including the economic side. An interesting 

 account is given of the survey of the Franz Josef and Blumen- 

 thal glaciers. The accompanying maps exhibit the portions of 

 the islands which have thus far been accurately surveyed. 



5. Report of the Mineral Survey of Ceylon, James Parsons, 

 Principal Mineral Surveyor. — In addition to the general state- 

 ment in regard to the mineral production of Ceylon, this report 

 notes the discovery of a new locality of moonstone at Weragoda 

 in the Southern Province. Thus far practically the entire world 

 supply of moonstone has been obtained from the rock leptynite 

 in the Kandy district in Ceylon. At the new locality the moon- 

 stone is obtained by sinking pits in the swamp through some i\ 

 feet of black mud, when a white kaolin is obtained, which, on 

 being washed, yields the gems. It is probable that here, as in the 

 Kandy district, it is derived from a similar rock in situ, but this
