5. Height of Mount Etna. 



Captain Smyth, in his lately published " Memoir of Sicily," 

 informs us, that, according to his measurements, Mount Etna is 

 10,874 feet above the level of the sea, and not 12,000 feet, the 

 height usually given to it. Prof. Schouw, in his " L'ultima 

 cruzione dell' Etna, descrita in una lettera diretta al Cavaliere 

 J. J. Alberto de Schaenberg, dal Dr. J. Schouw, Giornale Enci- 

 clopedico, Agosto, 1819," gives nearly the same height to the 

 mountain ; it being, according to his measurement, 10,484 

 French feet above the level of the sea. — (Edin. Phil. Journ.) 



6. Mediterranean. 



The medium heat of the sea around Sicily, at a depth of from 

 10 to 20 fathoms, by Six's thermometers is from 73° to 76°, 

 which, being 10° or 12° warmer than the water outside Gibraltar, 

 accounts for the greater evaporation, and consequent currents.
