observable, although the total amoiint of difference at points 

 many miles distant may be very considerable. The level of 

 the water will, therefore, be lower under a higher pressure, 

 and higher under a smaller pressure of the atmosphere, and a 

 tendency to equilibrium will result. These ideas of Schulten, 

 although well known in Stockholm, have not attracted, in 

 other countries, the attention they deserve. Lately, they have 

 received a confirmation from Daussy, Ann. de Chim. et de 

 Phys. 62, p. 304, who, without being acquainted with Schul- 

 ten's memoir, has made observations at Lorient, on the great- 

 est height of the surface of the sea at high water. These, ac- 

 companied by barometrical tables, have been published, and 

 exhibit, in a most complete manner, the phenomenon to which 

 we have now alluded. I consider it unnecessary to quote the 

 details of the observations. — Berzelius^ s Jahres-Bericht, Sieben-

3. Dr Berendt's Investigations on Amber. — We learn with 

 much satisfaction, from a letter sent us very recently by Dr 

 Berendt of Dantzig, that his important work on the insects, 

 &c., found imbedded in amber, and which, though commenced 

 in 1830, has been interrupted in its publication, is now to 

 be carried on and completed with as little delay as possible. 

 The first part contains an analytical or rather synthetical 

 account of the amber tree, and of the flowers and fruits 

 of other vegetable productions which grew in the amber 

 woods. Dr Berendt has transmitted to us the fifteen litho- 

 graphed plates illustrative of his second part, and Avhich 

 have greatly interested and surprised us by the richness 

 of the Entomological Fauna they exhibit. These figures re- 

 present the Ci'ustacea, Myriopoda, Arachnidse, and Aptera, 

 examined by the author ; and it would appear that all the 

 species found in amber are now extinct, and that but a small 

 number of the genera at present exist. Many new genera 

 have therefore been formed, and also one entirely new family. 

 Of the latter, the species Archcea paradoxa, figured in plate 

 2d, at once arrests the attention by its singular structure and
