fathoms. I paid special attention to sounding all the 

 channels and a few lines at right angles to the Plateau 

 of the Maldives. 



The weather has been superb — we lost only one day. 

 Taking all our meals on deck, we were driven below only 

 one day in the South Maldives at Addu, where it always 

 blows and rains pitchforks. The Sultan was most atten- 

 tive and so were all the natives. 



Agassiz had now visited practically all the important

 had he seen an atoll or barrier reef whose formation he 

 thought could be satisfactorily explained by subsidence. 

 It naturally followed that his final conclusion was a 

 total dissent from Darwin's theory on the subject. 



It had always been Agassiz's intention to embody his 

 coral reef investigations in a semi-popular summary ; 

 somewhat such a treatment of the subject as the " Three 

 Cruises of the Blake " was of oceanography. This un- 

 finished book caused him much trouble ; he never took 

 kindly to semi-popular work, and although in the last 

 few years of his life he was constantly returning to it, 

 he was not convinced of its utility. He used to say that 

 all his views on the subject could be found in his vari-

 until the last moment. At his death nothing 1 could 

 be found but a vast collection of extracts from the 

 literature of the subject marked and scored, and a few
