In future lists of the fossils it would be convenient if the names 

 •of authors were appended ; and the opportunity might be taken to 

 correct some misprints in the names. 



The Report contains a general geographical and geological de- 

 scription of the Victoria, Murchison, Gascoyne, Ashburton, Fortescue, 

 Eoebourne, and De Grey districts, with particular accounts of the 

 mineral resources. 



Alluvial gold was found by the Ashburton river in 1890; it has 

 been derived from mineral veins in clay-slates. These slates are 

 highly inclined, and on their upturned edges rest limestones and 

 other strata of Devonian and Carboniferous ages. The Ashburton 

 gold-field yielded about 15,000 ounces of gold in six months. At 

 present only the rich patches in the shallow ground have been 

 worked ; the deep ground is as yet untouched, although in the large 

 plains of the Ashburton river rich deposits are sure to be found, and 

 it is likely to prove a permanent goldfield. 



Mr. Woodward remarks that "as the prospecting will be most 

 expensive woi'k, no one will undertake it, unless he be granted a 

 protection area, until the course of the leads has been ascertained." 



The Pilbarra Goldfield is also reported to be " one of the most 

 promising mineral areas in this Colony." Particulars are likewise 

 given of the progress of the Yilgarn and Kimberley Goldfields, of 

 the Greenbushes Tinfield, and of the Collie Eiver Coal-district. 



The Collie Coal is stated in the Report to be "a Mesozoic coal, of 

 first class quality," but from specimens subsequently submitted to 

 Mr. Etheridge, he expresses his belief that it is " a good and true 

 iPalgeozoic coal" {West Australian, Jan. 13, 1892). The question of 

 age will not seriously afPect the colonists, so long as the coal is good, 

 and there is plenty of it. The extent has yet to be proved.

IN the Introduction the rocks and minerals supplying materials 

 for construction are enumerated and briefly described, and then 

 referred to their respective geological ages and formations. A biblio- 

 graphy relating to building-materials is also given. 



The contents of this useful work are arranged thus : — I. Austrian- 

 Hungarian Monarchy : A. Cisleithania ; 1. Lower Austria, especially 

 Vienna, with illustrations of St. Stephen's, the Votive Church, 

 Government Buildings, Townhall, Natural-history Court-Museum, 

 Marie-Therese Monument, the University, Court-Town-theatre, and 

 the Court-Operahouse. The enumeration, definition, and localities 

 of the several kinds of natural and artificial stone, plaster, etc., 

 .are carefully given, as road-materials, paving-stones, brick-earths, 

 mortar-sand, lime, cement-stones, building-stones, decorative-stones,
