organic remains. — -Major Zieten has begun the publication of a 

 work on the Fossils of Wurteniberg, (iiber die Versteinerungen 

 Wurtcmbergs), to be in 12 numbers. The first number con- 

 tains the Ammonites. Each will cost about 6s. in black. — 

 Deshayes of Paris continues his excellent work on the fossils, 

 shells, &c. of France. — Goldfuss of Bonn is advancing with his 

 interesting series of plates of Fossil Organic Remains. — Chil- 

 dren's work on Fossils does not appear. 



15. Memoirs of the Society of Strasbiag. — The first volume 

 of the new memoirs of the Society of Strasburg has just appear- 

 ed. It contains, 1. An extensive paper on Belemnites, with 

 plates by Voltz. 2. On the Jura Limestone, and caves of the 

 Haute Saone, by Thirria. 3. On the fresh-water gypsum of 

 Hegau (Baden) by Dr Althaus. 4. On the pea iron-ore of 

 Randern by Walchner. 5. On the fibrous boracite found in 

 keuper-gypsum. 6. On vertical strata. 7. On the mineral wa- 

 ters of Sulz. 8. On the primitive floras of the earth, by Voltz ; 

 it is an answer to Brongniart's observations on the subject. 



16. On the Alluvium of the Nile. — It is mentioned by au-

 a distance of about two leagues, is a work of the Nile : that 

 Damietta, during the first crusade of St Louis, was on the bor- 

 der of the sea, hence that this alluvial formation must have been 

 the produce of at least 600 years. — The work of Mr Reinaud, 

 entitled, " Extraits des Historiens Arabes, relatifs aux guerres 

 des Croisades,'" shews that the influence of these alluvia has 

 been exaggerated ; for in tliat work it is said, in conformity 

 with the testimony of oriental writers, that immediately after 

 the departure of St Louis, the Egyptian Emirs, wishing to pre- 

 vent a new invasion on the same side, razed Damietta, and 

 founded a new city in the interior of this district. This is the 

 present city of Damietta. 



17. Mortality among Leeches during Storms. — That atmo- 

 spheric changes have a remarkable influence upon leeches, is a 

 well-established fact. In 1825, M. Derheims of St Omer, 

 ascribes the almost sudden death of them at the approach of, or 

 during storms, to the coagulation of the blood of these creatures, 

 caused by the impression of the atmospheric electricity. This
