We may here remark with reference to the desiderata of 

 our correspondent on this subject, page 497, that India affords 

 an excellent field for deciding this question, were meteorolo- 

 gical registers simultaneously kept at different points from 

 Cabul to Ceylon, exhibiting the duration and number of 

 thunder storms in a given number of years at each place.* 



Notice of elevated Sea-Beaches, by Allan Stevenson. The 

 notice refers to two ancient raised beaches in the isle of 

 Mull, one 25 and the other 40 feet above the level of the sea. 



On the difference of level between the Dead Sea and the Me- 

 diterranean. Professor Schubert, Messrs. Moore, Beek, and 

 Berton were each separately and simultaneously employed 

 on this problem, when the last Russian expedition was oc- 

 cupied in its solution. Professor Schubert fixes the eleva- 

 tion and depression of various points as follows : — 



The edge of the mountains of the upper valley of the 

 Jordan he found to be 850 above the sea. The plain of 

 the Jordan near Jericho 528 below the sea. Lake of Tibe- 

 rias 535 feet below the sea level. Northern corner of the 

 Dead Sea 600 feet below the Mediterranean. The above 

 are Parisian feet. M. Callier, from the table of Barome- 

 trical observations made by Berton without regard to any 

 great nicety, calculates the level of the Dead Sea at 1249.8 

 Parisian, or 1^330 English feet below the Mediterranean. 

 M. Callier, from the observations on the boiling point of 

 water by Messrs. Moore and Beek, which they found to be 

 216.5 Fahr. makes the depression of the surface of the 



* Capt. J. Campbell, Assistant Surveyor General, Madras, has propos- 

 ed to keep a meteorological register in conjunction with other obser- 

 vers in various parts of India, with the view of determining this and 

 other questions of similar importance in meteorology. We shall be 

 happy to keep a diary in Calcutta, and communicate with observers in 

 other parts. — Ed. Cal. Journ. Nat. Hist.
