and in relation to the latter, interesting details are given of the 

 various tests made on the flow of underground water at Fulboum 

 in connexion with the Cambridge water supply. 



The latter part is devoted to a detailed list of well-sections and 

 analyses of the various well waters. 



In connexion with the well-sections there is a lot of information 

 which will be extremely useful to geologists as to thickness of strata 

 and depth to the Greensand, etc. 



A complete bibliography and index add to the usefulness of an 

 excellent work.

OsMiRiDiUM IN T.ASMANiA. By A. M. Reid. Bulletin 32, 

 Geological Survey of Tasmania, pp. vii-|-126, with 10 plates 

 (maps) and 12 full-page photographs. 1921. 



f\F late years there has been a considerable demand for the natural 

 ^^ alloy osmiridium or iridosmine for the points of gold nibs for 

 fountain pens, and prices until lately ruled very high. Tasmania 

 is to-day the largest producer of this valuable metal. A remarkable 

 feature is the comparative scarcity of associated platinum in the 

 deposits, which nevertheless are derived from ultrabasic, usually 

 serpentinized intrusions, as in the case of the normal platinum 

 occurrences. Hitherto the output has been chiefly obtained from 

 superficial and alluvial deposits, but the metal has been definitely 

 located in its mother rock, which has also been worked commercially 

 to some extent. In their unaltered condition the metalliferous 

 rocks are mainly bronzite-peridotites, while pyroxenites and their 

 derived serpentines are barren. The chief deposits are found in the 

 river-gravels of the Western Division, while the best-known rock- 

 deposits are those of Bald Hill, Mt. Stewart, and Wilson River. 

 Much of this country is very wild and inaccessible, and there 

 are possibilities of much future development of the industry, 

 though at present owing to a slump in prices it is not very profitable. 



NeMORHAEDUS PHILISI, NOV. SPEC. EIN FOSSILER GoRAL AUS DEM 



Oberpliocan DER AuvERGNE. By S. ScHAUB (Basel). Eclogse 

 Geol. Helvetise, vol. xvi. No. 5, January, 1922, p. 558. 



TN this paper the author describes the remains of at least two 

 -^ individuals of a new species of Nemorhaedus (the Goral), a genus 

 of antelopes related to Ca'pricornis (the Serow) and to Budorcas (the 

 Takin),. all confined at the present day to the eastern half of Asia. 

 The material, which includes skulls and most of the skeleton, is so 

 good that there seems to be no reason to doubt the accuracy of the 

 determination. The discovery of this Asiatic form in western 

 Europe is particularly interesting because it probably represents the 

 ancestral form of the peculiarly modified antelope Myotragus 

 discovered by Miss Bate in Pleistocene cavern-deposits of the
