216 New Publications, 



present one with much rapidity or regularity, owing to the ob- 

 stacles arising from the expense of the undertaking, the delay 

 caused by the translation, and the time required for the prepa- 

 ration of the maps and plates, &c. The Royal Norwegian So- 

 ciety of Sciences at Drontheim has, with becoming liberality, 

 given pecuniary aid to the publication. The first number is 

 of itself a very valuable addition to our geological literature, 

 and is chiefly composed of an excellent detailed account of the 

 transition district of Christiania, by Professor Keilhau, which 

 is accompanied by a well executed and minute geological map 

 and good sections ; but also contains a paper on the primitive 

 serpentine of Modum, by Mr Bobert, inspector of the cobalt- 

 mine at Modum ; and a general view of the Norwegian trilo- 

 bites (no less than forty-eight species), by Mr C. Boeck. 



2. Lethcea Geognostica ; or Figures and Descriptions of the Characteristic 



Petrifactions of the different Rock-Formations. By Dr G. H. Bronn. 

 4to. Heidelberg. 1837. 



This excellent work, which we have already repeatedly noticed, 

 is now nearly finished, one number only remaining unpublished. 

 Its beauty, accuracy, utility, and cheapness will, we doubt not, 

 procure it a place in every geological library. 



3. A Systematic and Stratigraphical Catalogue of the Fossil Fish in the 



Cabinets of [Lord Cole and Sir Philip Grey Egerton, together with an

 references to their published figures and descriptions. By Sir Philip 

 Grey Egerton, Bart. M.P., F.R.S., F.G.S. 4to. London : 1837. 



The student of palaeontology will prize highly the very in- 

 teresting tables in this unpretending catalogue ; which, al- 

 though extending over comparatively but few pages, contains 

 much valuable and accurate information. 



4. The Zoology of the Voyage of H. M.S. Beagle, under the Command of 



Captain Fitzroy, during the years 1832 to 1836, Part 2d. Mammalia, 

 with numerous Plates. By George R. Watbrhouse. Esq., Curator of 

 the Museum of the Zoological Society. Smith, Elder & Co., Lon- 

 don. 



This part of the Zoology of the Beagle, contains a short but
