Fenton — Physiography and Glacial Geology of S. Patagonia. 225 



In conclusion, I wish to tender my most sincere thanks to Professor 

 Cole for the encouragement he has always given me, and the kind interest he 

 has taken in my studies from the beginning. He first taught me to take an 

 interest in geological matters, and has very kindly read over the present 

 paper, and given me many valuable suggestions on the interpretation of the 

 facts observed.
