A SCIENTIFIC commission, consisting of M. Milne 

 Edwards, M. Blanchard, and myself, was appointed, 

 in the Autumn of 1843, to visit the coasts of Sicily 

 by the Minister for Public Instruction, the Jardin 

 des Plantes, and the Academy of Sciences.* In ac- 

 cordance with our plan of travelling together, we all 

 left Paris on the 20th of March, 1844, and on the 

 28th of the same month we reached Naples. In 

 eight days we had traversed the whole of France ; 

 we had taken a glance at Lyons and Marseilles,
