swum, A. venustum, A. pubescens, and A. villosum, Adiantum macrophyllum, A. 
serrulatum, A. radiatum, A. cristatum, A. trapeziforme, and A. tenerum, Cheil- 
anthes microphylla, Davallia alata, Dicksonia cicutaria, Woodsia pubescens, Cy- 
athea elegans, Trichomanes sinuosum, T. crispum, and T. scandens, Psilotum 
triquetrum, and Lycopodium cernuum. In certain wooded districts of the 
Island, the ferns are very splendid and exceedingly beautiful in their form ; 
the segments of their multifid fronds, moving with the slightest breath of air, 
are constantly in motion, and give them a most elegant and graceful appear- 
ance ; the newly-arrived botanist cannot but be struck with wonder at such 
a display of ferns, mostly unknown to him; and he is enabled to make a 
plentiful collection at a small expenditure of labour. Article the second is a 
monograph of M. Desjardins’, on the genus Leptocera, with descriptions of two 
new species found in the Isle of Bourbon: the Leptocera mezierei and L. 
beaumontii are the names he has assigned to them, in honour of two distin- 
guished entomological friends. Mr. Clarke, in an ingenious experimental 
essay on the organs of hearing in insects, with thirteen illustrative figures, 
concludes that these creatures “could hear as plainly as he could himself,” 
that their antennz are the organs of hearing, and that the upper part of the 
antennze has the power of increasing sound. In a communication on the 
Succinea amphibia, or amber-shell, and its varieties, Mr. Cooper points out 
some long-prevailing errors respecting this mollusc, and he gives six figures 
in explanation of his observations. Some entertaining as well as instructive 
remarks are contributed by Dr. Clarke, on the habits of the Coluber natrix, 
or common snake. Sir E. F. Bromhead proceeds with his remarks on zoolo- 
gical classification; and these are succeeded by Mr. M’Coy’s strictures on 
Mr. Eyton’s arrangement of the gulls; and by Dr. Hancock’s notes on the 
Psophia crepitans, or trumpeter bird, the waracobdi of the Arowahs of Guiana. 
Next, come Mr. Ogilby’s reasons respecting the term Simia and its applica- 
tion; then Mr. Swainson replies shortly to some of his reviewers; and then 
are appended some notes by the Editor, relating to the same question.— 
Under the section intituled scientific intelligence, you see a letter of Lord 
Tankerville’s on the wild cattle in Chillingham Park, and notes on the elec- 
tric eel, on Artesian wells, on the electrical telegraph, and on the natural 
history of Nowaja Semlija and the Caucasian regions. Mr. Blyth’s remarks 
on the doctrine of spontaneous generation; observations on the Oubudi, or
