166 THE VICTORIAN NATURALIST. 



colonies." As scarcely any reference is made to rocks from other 

 colonies, and none to the remarks made by extra- Victorian 

 geologists as to the age of some of our formations, we find no 

 hint of the occurrence of rocks that are referred to Archaean, 

 Cambrian, Permo-Carboniferous, Marine Jurassic, or Cretaceous: 

 and though the subdivisions Eocene, Miocene, and Pliocene 

 certainly are recorded, yet an examination of the catalogue will 

 show that this reference dates from a period anterior to that at 

 which Professor M'Coy decided that we had no Eocene rocks in 

 Victoria. 



To attempt to point out all the errors would be a task far too 

 long, and we shall content ourselves with a few that certainly 

 should be corrected : — 



Page 9. — The granite used in the construction of the present 

 Prince's Bridge came from Harcourt, the Gellibrand's Hill granite 

 being used in a previous bridge which was removed some years 

 ago. 



Page 10. — Auriferous quartz reefs in typical granite have been 

 recorded near Heathcote by E. J. Dunn. (Reports of Mining 

 Surveyors, December, 1888, page 76.) 



Ulrich's reference of the occurrence of Nepheline in the Older 

 Basalt of Phillip Island has been dropped, and Apatite is recorded 

 in its place. Surely some hint of the change should have been 

 given, as Ulrich's remarks have been copied into various works. 

 Ulrich's descriptions are reprinted word for word with this single 

 alteration (specimens 7.5, 7.6, 7.9). 



Page 36. — When will the old mistake of Mount Eels for Mount 

 Eccles be corrected ? 



Page 43. — Obsidian still appears on our lists, and has not yet 

 been ousted by Tachylite. 



Page 44. — There is no newer basalt at Maldon, and the Zeolites 

 quoted occur in a quartz-felsite dyke. 



Page 46. — The older basalt of Chetwynd (No. 7.24) is of 

 Mesozoic age, as its ashbeds contain Otozamites (Dennant, Proc. 

 Aust. Ass., Adelaide, page 395). 



Page 58 (No. to. 6). — Mr. Howitt has identified a dyke-stone 

 from the Eaglehawk Reef, Maldon, as Diallage rock. Possibly 

 the reference to Amphibolite, then, is incorrect, as microscopic 

 examination is required for their separation. 



Page 72. — A Lower Silurian limestone — certainly, of very small 

 thickness— is recorded from Bendigo by E. J. Dunn. The 

 fossils of our Lower Silurian rocks are not similar throughout, and 

 subdivisions founded on palgeontological differences have been 

 made. 



Page 74. — Since the publication of Selwyn's map a fresh one 

 has been issued by the Mining Department, under the direction 

 of Brough Smyth, and even a new edition of this is promised.
