Redews — Geology of South Australia. 41 



for the most part, in such perfect preservation that, in looking 

 over the plates, we can scarcely realize that the ligures represent 

 fossil forms of Silurian age. Prof Linclstrom has in this monograph 

 extensively increased our knowledge of the Silurian Gasteropoda, and 

 all students of Palfeozoic fossils are indebted to him for this fresh 

 contribution to palaeontology. The working palEeontologists of this 

 country and America are under special obligations to him for 

 bringing out this work in the English language, and thus affording, 

 to not a few, readier access to its contents. It is a bold undertaking 

 for an author to write an important monograph like this in a foreign 

 language, especially when that language is English, and we con- 

 gratulate Prof, Lindstrcim on the success attending his effort. Nor 

 ought we to forget the munificence of the Royal Swedish Academy 

 of Sciences in finding the funds for publishing this work. 



"When we consider the numerous admirable scientific memoirs 

 which this Ptoyal Academy has lately published, notably amongst 

 others the magnificent memoir on Fourtalesia, by Prof. Loven, the 

 colleague of Prof. Lindstrcim in the Royal Museum at Stockholm, 

 we feel that the contrast between the scientific activity in Sweden 

 and the support it receives, and the condition of things in this country, 

 is not altogether flattering to ourselves. G. J. H. 



v.— Annual Report op the Government Geologist por South 

 Australia (Henry Y. Lyell Brown, F.G.S.), December 

 1st, 1882, to December 31st, 1883. Fol. pp. 20; with nine 

 page-sections and plans, and one large folding chromolitho- 

 graphic map of South Australia, exclusive of the Northern 

 Territories. (Adelaide: September, 1884.) 



THE first Annual Report of the Geological Survey of South 

 Australia was noticed by us in this Magazine (Decade III. 

 Vol. I. January, 1884, pp. 29-32), and it is highly gratifying to 

 find that Mr. H. Lyell Brown has been able to compress so large an 

 amount of work into the thirteen months which are embraced in the 

 present publication. 



It is difficult for any one here in England to realize either the 

 vast extent of the territory of South Australia (ten times that of 

 Great Britain) or the almost entire absence of easy and rapid means 

 of intercommunication between its widely-spread and thinly-scattered 

 population. No wave of gold-field-fever has as yet disturbed the 

 agricultural calm of this large and well-to-do Colony ; but there 

 has arisen a very natural desire, on the part of its Government and 

 people, to know what are the Mineral resources of the Colony. 

 Mr. Lyell Brown has set to work with a will to furnish this infor- 

 mation to the Government, and has sacrificed all considerations 

 of personal ease and comfort to travel over many thousand miles of 

 country in order to produce the admirable sketch-map of the Geology 

 of South Australia which accompanies the present report. 



The project for a trans-continental railway from Adelaide in the 

 South to Port Darwin in the North, upwards of 1400 miles, has
