IO4 AUTOBIOGRAPHY. 



as facts are shown to be opposed to it. Indeed, I 

 have had no choice but to act in this manner, for with 

 the exception of the Coral Reefs, I cannot remember a 

 single first-formed hypothesis which had not after a 

 time to be given up or greatly modified. This has 

 naturally led me to distrust greatly deductive reason-

 old Kentish man, and asked him whether he had 

 heard anything about it, and he answered, " Oh, no, 

 sir, it must be a mistake, for the beans grow on the
