 theory, might well disturb even a philosopher of 

 Darwin's serenity. 



However, both Hooker and Lyell had read his 

 sketch a dozen years before, and it was arranged by 

 them, not as considering claims of priority, which 

 have too often been occasion of unworthy wrangling, 

 but in the " interests of science generally," that an
