anything but elucidated by the recent discussions to which it has given rise in 



England. N. Wood's Reply to C. J.'s Remarks on the " British Song 



Birds," p. 566 On the Habits of the American Flying Squirrel, (Pteromys 



volucella, Cuv.) by D. W. C. p. 568. A very pleasing paper Berkeley on 



the Occurrence of Dreissena polymorpha, Vanbeneden, in Northamptonshire, 



p. 572. Blyth on the Birds observed, during the last four years, in the 



Vicinity of Tooting, Surrey ; with Remarks on their comparative Numbers and

In neither Number is there any original Botanical communication, excepting what 

 is to be found among the " Short Notices," which are as various and numerous 

 as hitherto. Of these, there is none we have read with so much pleasure as the 

 Anecdotes of the late Mr Purton, author of the Midland Flora ; and we do hope 

 that, in the New Series of this Magazine begun with the present year, an effort 

 will be made, by the industrious Editor, to supply us with similar, or rather 

 more copious, notices of such lovers of Natural History as may be annually sum- 

 moned to that bourne whence no traveller returns.
