3. The Atlas of Physical Geography. Constructed by Augustus 

 Petermann, F.R.G.S. Imperial quarto, pp. 142. London : Wm. S. 

 Orr & Co., 1850. The distinguished favour with which the public re- 

 ceived the important Physical Geography of Professor Berghaus of 

 Berlin, and the no less successful reception given to the magnificent 

 Physical Atlas of our intelligent townsman Mr Alex. Keith Johnston^ gave 

 rise, and that speedily, to other similar but less extensive worJcs on the 

 continent of Europe and also in this island. Of these, the best we 

 have seen is that of the well-known and experienced geographer, 

 Augustus Petermann, Esq. {now resident in London), which we recowr- 

 mend on account of its geographical accuracy and great beauty of 

 execution. 



4. A Sketch of the Physical Structure of Australia, so far as it is at 

 present known, with two Geological Maps. By J. Beete Jukes, 

 M.A., F.G.S., late Naturalist of H.M.S. Fly. T. & W. Boone, 29 New 

 Bond Street, London, 1850. To those interested in the geology of 

 Australia we particularly recommend this volume, by Mr Jukes, a 

 gentleman "very favourably and generally known as an enterprising 

 traveller and judicious observer. The accompanying coloured geological 

 maps add to the value of the work. 



5. An Introduction to the Atomic Theory. By Charles Daubeny, 

 M.D., F.R.S.L. Second edition, greatly enlarged. Oxford : At the 

 University Press, 1850. Dr Daubeny has, in this edition of his work 

 on the Atomic Theory, added much to interest the chemist and general 

 reader. 



6. Geognostische Briefe aus den Alpen. Von Bernard Cotta (Letters 

 from the Alps.) Leipzig : J. 0. Weigel, 1850. These interesting and 

 instructive Letters, by the present occupant of the Geognostical Chair of 

 Werner, at Freyberg, independently of incidents of travel, give us an 

 agreeable and generally accurate account of the Geognosy of the Alps, a 

 subject of high importance as bea/ring on the general geology of Europe. 

 They shew that the colossal mountain groups forming the European 

 Alps exhibit, as we long ago pointed out, a structure very different from 

 that of the Alps of Scotland. Ere long we trust to see British 

 geologists occupied in working out the true geology of the Caledonian 

 Alps. In this important investigation they will be materially assisted 

 by these Letters of Professor Cotta— a translation of which we believe 

 would be welcoTned by our geologists. 



7. Graptolitesde Boheme, par Joachim Barrande. Extrait du Systeme 

 Silurien du Centre de la Boheme. 8vo, pp. 74, with plates. Prague, 

 1850. Our excellent friend, M. J. Barrande, whose important geologi- 

 cal investigations in the Silurian ( Transition) distncts of Bohemia, so 

 deeply interesting to geologists, has published, under the above title, as 

 an extract from, his forthcoming great work on Bohemia, a very excel- 

 lent account of those curious fossil animals the Trilobites. This account 

 we recommend to the particular attention of the geologists of Scotland^ 

 as similar organic remains have been met with in Dumfnesshire, Peebles- 

 shire, and Kirkcudbrightshire. The valuable account of M. Barra/ndt's 

 work, by our former pupil and friend Professor Nicol of Cork, contained 

 in the present number of the Philosophical JounuU, will enable our 

 readers to judge in a general way of the important information expected 

 from the " Systeme Silurien" of M. Barrande.
