^HHE published works, pam- 

 phlets, and monographs 

 of Louis Agassiz have 

 never been completely- 

 recorded, but even a 

 casual review of the list 

 known is suggestive of 

 the phenomenal labours 

 of the great thinker and 

 investigator in the world 

 of science. The pub- 

 lished works of Agassiz, 

 which were milestones in 

 the development of his career, have been casually 

 referred to in the previous pages, but they were so 

 epoch-making, had so marked an effect upon the 

 scientific thought of the time, that some special 

 mention may add to the interest of the story.
