allowed him, in the most unfavourable season of the year, for the 

 accomplishment of the object of his mission. Premising, therefore, 

 that the route was restricted to the sea-coast, diverging inland only 

 when the depth and force of the streams that empty themselves into 

 the sea rendered their passage dangerous, and compelled a detour to 

 a more narrow or shallow part of the river-channels, and that no 

 leisure was permitted for the accurate investigation of geological 

 pheenomena, I proceed without farther comment to the extracts from 

 my son's note-book : I will afterwards briefly describe the specimens 

 of rocks and organic remains, and conclude with a few general ob- 

 servations on the facts submitted to the consideration of the Society.
