Zoological Classification. A handy book of reference, with tables of the 

 sub-kingdoms, classes, orders, &c, of the animal kingdom, their 

 characters, and lists of the families and principal genera. By 

 Francis P. Pascoe, F.L.S., &c. Second edition, with additions 

 and a glossary. London : John Van Voorst. Price 12s. 



The title of this book accurately describes its contents. It is what it 

 purports to be, " a handy book of reference to the classification of the 

 animal kingdom," and its aim, " to bring the contents of the various 

 groups under the eye in the most concise and simple form," is success- 

 fully achieved. The works of Schmarda and Claus have been made 

 abundant use of, embodying, as they do, the most recent views of German 

 Naturalists. An excellent glossary distinctively adds to the value of the 

 book, and, though the definitions are brief, they are terse and clear. The 

 index, too, is a most useful one ; so far as we have tested, it is full and 

 accurate. It gives us great pleasure to commend this book most warmly ; 

 it deserves a place in every Naturalist's library. E. W. B. 



Santorin et ses Eruptions. Par Fouque. Paris, G. Masson, 1879. Price 



72s., 438pp., and sixty-one large plates, 4to. 

 In this splendid work Professor Fouque gives an excellent account 

 of modern volcanic action as exhibited in the island, or rather group of 

 islands, called Santorin, in the Grecian Archipelago. The appearances 

 presented by Santorin are precisely those which would be seen if 

 Vesuvius were sunk below the sea till only the central cone and the rim 

 of the old crater (Monte Somma) stood above the water. The eruptions 

 at Santorin are now confined to the central cone, which stands on an 

 island in the centre of a great circular bay, whose vertical cliffs show 

 magnificent sections of ash beds and lava flows. The illustrations of this 

 work are very fine, and give a graphic idea of the scenery and geology of 

 the district. Professor Fouque has given great attention to the 

 microscopical examination of the rocks, and his observations and 

 beautiful drawings of magnified rock-sections will be of great value to all 

 students of igneous rocks. Vv". J. H. 



Tenth Annual Report of the Wellington College Natural Science Society, 



1879. 

 This volume contains a great amount of valuable and interesting matter,
