Manual, should be known to every geographer who devotes a portion 

 of his time to observations on terrestrial physics. 



Lastly, Mr. Mallet under great privations re-explored, almost im- 

 mediately after the recent occurrence of the great earthquake, the 

 provinces of the kingdom of Naples, nearly from Bari to Calabria, 

 and has collected many striking particulars, including great topo- 

 graphical changes of the surface, an account of which will be laid 

 before the Eoyal Society of London, at the desire of which learned 

 body he made his journey, and I look forward with deep interest to 

 the publication of his results. 



New Publications, Maps, Surveys, etc. 



The ' Manual of Geographical Science ' (Parker and Son), the 

 first part of which appeared in 1852, having been completed this 

 year by the addition of a well digested volume, can now be recom- 

 mended to the public as a most useful and instructive work. The 

 first portion embraced mathematical geography, physical geography, 

 cartography, and geographical terminology. The new volume con- 

 tains a learned and interesting history of ancient or comparative 

 geography, by the Eev. W. L. Bevan ; whilst the last 400 pages of 

 the book, which are written by our indefatigable associate the Eev. 

 C. G. Nicolay, are devoted to the progress of maritime discovery, 

 and a description of the surface of the earth as now known to us. 

 The lucid manner in which this author explains the relations of 

 land and water, as well as all the leading physical outlines and 

 waterpartings of continents, must have a most beneficial influence 

 in impressing upon students the elements and principles of geogra- 

 phical science. 



Among the communications to our Society I was much gratified to 

 find the eminent astronomer. Sir John Herschel, coming before us 

 in the last session with a new and ingenious projection of the sphere. 

 The author shows that his projection offers several peculiar advan- 

 tages for geographical purposes, particularly when the whole, or at 

 least the whole accessible part of the globe, has to be mapped down 

 on one sheet. 



The astronomical experiment on the Peak of Teneriffe, which 

 was carried out in 1856, under the sanction of the Admiralty, by 

 Professor C. Piazzi Smyth,* is chiefly of interest to this Society 



* Parts of this work were published in the ' Philosophical Transactions ;' but the 

 whole work, as now brought out by the Admiralty, 1859, contains three additional
