tributaries is fertile and highly cultivated lowland. The geological 

 formations are grouped as follows : — 



Eecent ...... Alluvial deposits, Travertine, etc.

1 Jenkins Hill Series Conglomerates, sandstones, 



shales, mudstones, limestones, 

 and occasional coal-seams. 



Late Mesozoic or Intrusive rocks of Ultra-basic rocks which pierce 

 Early Cainozoic "Mineral Belt " the Matai Series. 



Trias-Jura . . Matai Series . . Conglomerates, breccias, grau- 



wackes, limestones, and argil- 

 lites, with contemporaneous 

 volcanic rocks. 



Among the fossils of the Matai Series are species of Spirigera, 

 Monotii, Halolia, Trigonia, and Gryplicea. The main object of the 

 work is to describe the nature and extent of the copper-deposits 

 which occur in the Mineral Belt. The associated rocks include 

 peridotites, serpentine, etc., and of these petrological accounts are 

 given. Other economic products of the district are gold, chromite, 

 coal, and building materials. 



YIII. — Cambridge County Geographies. — We have received the 

 volume on ISTorth Lancashire by Dr. J. E. Marr (Cambridge, at the 

 University Press, 1912, price Is. 6</.). It contains a capital account of 

 the physical features, with brief references to the geological structure. 

 The mountains ; the fells, some of which are rocky and step-like, while 

 otliers are peat-covered moorlands ; the watersheds and passes, the 

 bare and fissured limestone-tracks known as 'dints', the lakes, 

 tarns, and rivers are duly if briefly described. There appear to be 

 no great forests, but much coppice, and charcoal-burning is carried 

 on for the manufacture of gunpowder. The iron-ore, building-stone, 

 the slate of Tilberthwaite, and rock-salt are among the industries of 

 geological interest. Many good views of scenery are given, and 

 there is a portrait of Sir Eichard Owen, who, as a Lancashire man, is 

 rightly given a place with Whewell and Sir Edward Erankland in 

 the section entitled ' Roll of Honour'. 



IX. — Brief Notices. 



L Geology of Wyoming. — A memoir on the Geology and, Mineral 

 Resources of a Portion of Fremont County, W'yo., has been written 

 by the State Geologist, Mr. C. E. Jamison (Bulletin No. 2, series B, 

 1911). An account is given of the various geological formations from 

 Pre-Cambrian to Tertiary (Eocene), of their structure and history, 

 with preliminary descriptions of the physical features, climate, and 

 agriculture. The chief mineral products are oil, gold, building-stones, 

 and gypsum. 



2. Western Australia. — We have received vol. i, pt. ii, 1912, of 

 the Records of the Western Australian Museum and Art Gallery, 

 edited by the Director, Mr. Bernard H. Woodward, F.G.S. In this 

 work Mr. L. Glauert continues an account of the mammalian remains 

 from the Mammoth Cave, describes some " Fossil Marsupial Remains
