Chevalier Dupin, Member of the Royal Institute of France, 

 and author of Voyages dans la Grande Bretagne, is about to 

 publish the second part of his Mathematical Researches, under 

 the title of Applications de Geometrie et de Mccka?iique. This 

 work, which form a 4to volume, with 16 plates, contains the 

 author's tlieories upon the stability of floating bodies ; upon 

 the researches relative to the best construction of roads over 

 soils of every kind, in various circumstances ; upon the removal 

 of any heap of materials of a speciiied figure, and forming there- 

 with another heap of a required figure {deblaiet irmblai); — upon 

 the laws according to which, rays of light, emitted from a single 

 point, are subjected in their various reflections from mirrors of 

 any form ; finally, upon the mathematical examination of the 

 new structure of English men of war.

Sowe?-bi/s Mineral Conchology. No. 65. 



PI. 372. Ampullaria amhidacruvi, one of the most common 

 shells from that mine of fossil conchology, Hordwell-cliff". 

 Mr. Sowei'by has very well distinguished it from two or three 

 other kindred species. Regarding the generic situation of 

 these shells, we cannot agree with either Cuvier or Lamarck. 

 That they have never been found excepting in marine forma- 

 tions, is a strong presumption against Cuvier's opinion that they 

 belong to the Ainptdlarice, of which all the recent species are 

 fluviatic ; while on the other hand we cannot possibly discover 

 why they should be separated from Natica as a distinct genus, 

 according to the supposition of Lamarck. We think, if any of 

 the species from Hovdwell-cliff are placed by the side of our com- 

 mon English Nalica glaucina, not a shade of difference in their
