reefs," soft clayey ferruginous material, with the quartz in the form of 

 coarse sand, and small angular and slightly rounded pieces. 4. Mas- 

 sive lodes, from 4 to over 20 feet thick, having well-defined walls with 

 clay casings ; some are traceable for miles along the strike. 5. Either 

 " layer lodes," or interlaminations between the beds of phyDite. 6. 

 The so-called Peninsula Quartz Reef at Portobello, where the gold 

 is disseminated in a finely divided state through trachyte-rocks. The 

 auriferous drifts are divided into newer and older. The former com- 

 prise the terrace formations of shingle and sand worked by sluicing ; 

 the latter, deposits of harder gravel and cement, known as " false bot- 

 tom," underlying the newer drift in certain old lake-basins, with 

 cement and gravel on the tops of some of the ranges. There are notes 

 on the occurrence of the minerals mentioned in the title, and 12 appen- 

 dices, comprising descriptions of various auriferous reefs. R. E., Jun.

 The introduction contains a few geological notes relating to former 

 expeditions. The Mount Wedge Range contains some remarkable 

 "glens;" the predominating rock appears to be basalt. Central 

 Mount Wedge is an isolated hill 1650 feet above the high saddle on 

 which it rests, with, at its E. side, a perpendicular scarp of red rock 

 615 feet high. From the Mt. Wedge Range to Mt. Farewell the pre- 

 vailing rock appears to be granite in isolated hills, mounds, and 

 patches. From long. 121° E. to 131° E. the country is occupied by 

 the " Great Sandy Desert " composed of sand hills and red sand ridges 

 interspersed with salt lagoons, clay pans, and soda springs, passing 

 northwards along the 20th degree of latitude into a high sandy table- 

 land. The sand ridges varj^ much in height and distaTioe apart, tho 

 average being 80 feet high, and 300 yards from one auothcr. They 

 run parallel with one another E. and W., but, unlike most sandy 

 deserts, are clothed with some vegetation. A note by Prof. Owen, 

 " On the Physical Configuration of Australia, and its Geological 

 Causes," is appended. R. E., Jun.
