was temporarily postponed, owing to increasing debility and the direct 

 advice of his physician. It was to have been given February 6. On 

 the small-page hand memorandum containing the catch-words of the 

 argument of each lecture, from which he elaborated his theme extempo- 

 raneously, and which was found on his desk after his funeral, he had, in 

 pencil, inserted an arrow-point denoting the place at which the course 

 was interrupted. This being absolutely his latest public work, it has

Feb. 6. — Philosophy of Evolution. 



What is Darwinism? Misapprehension of causation. Relation to 

 environment conditional ; not casual. Cause acts now and here. The 

 efficient cause in the organism. The efficient cause immaterial. The
