1 have not yet made observations with a view to decide if 

 the above description of the development of the stomata agree 

 with all cases, or whether in other plants it presents essential 

 modifications in the process of this operation ; but it is pro- 

 bable enough that the first method of development indicated 

 by Mirbel in no case presents itself in an isolated manner, 

 but that it is only the commencement of the second mode ; 

 that there is no absorption of the central cell ; and that this, 

 in the Marchantia, divides into four, as it separates into two 

 in the Hyacinthus orientalis.

The Natural History of South Devon. By J. C. Bellamy, Surgeon. 

 Plymouth, 1839. 8vo. pp. 456. 



It is only by collecting diligently facts from every part of a country, 

 that we can expect to arrive at those general principles which regu- 

 late the distribution of plants and animals over its surface. In this 

 respect every work that contributes to the information we already 

 possess ought to be hailed as the omen of progress in our knowledge 

 of the natural history of the earth. We have already had many able 

 attempts at giving complete views of the distribution of animals and 

 plants in many districts of our own island, and we have now to add 

 another to the list. Mr. Bellamy has produced an interesting volume 

 with regard to the dehghtful county in which he dwells, which will 

 not only be read with pleasure by those who reside on the spot, but 

 will be welcomed by the naturalist as an accession to British natural 

 history. 



Mr. Bellamy's work is divided into three parts. The first part is 

 divided into five chapters, and treats of the geological character of 

 South Devon and the nature of its climate. The structure of the 

 strata in this district is minutely described, and several new and in- 

 teresting fossils are described and figured. The second part is occu- 

 pied with lists of the vertebrate and invertebrate animals of the di- 

 strict, with the exception of the insects, and with various observations 

 of the author on the animals of South Devon. The third part is de- 

 voted to " Remarks on numerous subjects of Natural History, but 

 more particularly on Birds." A great number of these remarks are 

 original, and are made in such a manner as cannot fail to interest the 

 general reader. 



In this volume Mr. Bellamy has introduced to our notice four ad- 

 ditions to the British Fauna. These are respectively named Arvicola 

 hirta, Mus intermedins, Sylvia neglecta and Helix subvirescens . We 

 cannot however pronounce upon the accuracy of the descriptions, nor 

 the value that ought to be attached to them, because we have not 

 the specimens before us. We hope, however, that the approaching 

 meeting of the British Association will enable some of our eminent
