alone, when compared with the artificial argumentations and hypo- 

 theses of the former. We must refrain from entering into the de- 

 tails of the work, but are sure that no impartial critic will deny it 

 the merit of at least a lucid and elaborate investigation on the subject 

 in question.

 RELATING TO THE NATURAL SCIENCES & PHILOSOPHY.

No. XXVIII, April, 1839 — First on the list for this month, are Madame 

 Power's observations on the poulp of the argonaut, with concluding remarks. 

 In a continuation of Dr. Bachman's monograph on the genus Sciurus, five 

 species are described ; and, in the two next articles, you have a notice of a 

 new species of Rotalia with eight figures, and a description of a new fossil 

 Avicula, represented in a very distinct figure. Mr. Garner proceeds with 

 his anatomy of the Lamellihranchiate Conchiferous animals, and treats of their 

 digestive, circulating, and respiratory systems: his is followed by Mr. Hope 

 with observations on forty-four of the Lamellicorns of Olivier, and by Mr. 

 Pellerin's structural differences in the crania of the four species of British 

 Swans, accompanied by the figure of a skull. Mr. Bird continues his artifi- 

 cial arrangements of the natural orders of British plants; and this is succeed- 

 ed by Mr. Waterhouse's observations on the Rodentia, with a view to point 

 out the groups as indicated by the cranial structure : eight figures give il- 

 lustrations. From the pen of Dr. Bird you receive a letter on the applica- 

 tion of Heliographic or photogenic drawing to botanical purposes, with an 

 economic mode of preparing the paper. An editorial article points out the 

 importance of Madame Power's experiments, the defects of the ^* Proceed- 

 ings of the London Botanical Society," and the advantages of publishing il- 

 lustrative plates in supplementary numbers. And the Short Communica- 

 tions relate to experiments on kyanised wood, ignes fatui, captures of eagles, 

 appearance of the bat, the migration of the swifts, improvements in the mi- 

 croscope, and to an anomalous apterous insect inhabiting the Spongiaj^uma^i- 

 lis, whose undulating motion it is supposed to produce. 



No. XXIX, May Extracts from the Proceedings of the Geological Society 



relating to the mammiferous remains of the Stonesfield oolitic strata, consti- 

 tute the leading article of this number : this paper is long and interesting.
