It will perhaps be thought that the nature of the organic remains 

 of this island throws light on the antiquity of the whole archipelago, 

 as the westernmost island of Flores contains calcareous beds which 

 may have been formed like those of St. Mary's, while the volcanic 

 character of the intermediate island constitutes a general chain of 

 connexion between them. And if those remains be found to be the 

 same with the fossils of Sicily, the Azores may perhaps be assumed 

 to be of the age of that and neighbouring parts of the land of the 

 Mediterranean.
