Tn tlie following pages, I propose to give a brief sketch 

 of the geologic and tectonic structure of the island-world of 

 South-eastern Asia, usually comprehended under the name of the 

 Malayan Archipelago. The motive of my taking up the present 

 subject was to enable me to compare the physical features of 

 the island of Taiwan with those of the Far Eastern Indies, there 

 being much in common between them. My notes have now so 

 far accrued as to make me hope that some service will be done 

 by their publication in a connected form. The great Viennese 

 geologist. Prof. E. Suess, has already drawn a lively picture of 

 the structure of these islands, in his 'Das Antlitz der Erde,' and 

 this I have made tbe foundation of my paper ; but as the IMa- 

 layan Archipelago fills only a small section of his work, and 

 has besides become much better known than it was when he 

 wrote about it, I have found it necessary both to enlarge and 

 to modify his account.
