 what we are called upon to say of the latter by briefly 

 comparing and contrasting the two. 



Robert Brown died sixteen years ago, full of years 

 and scientific honors, and he seems to have finished, 

 several years earlier, all the scientific work that he had 

 undertaken. To the other, Charles Darwin, a fair 

 number of productive years may yet remain, and are 

 earnestly hoped for. Both enjoyed the great advan- 

 tage of being all their lives long free from exacting 

 professional duties or cares, and so were able in the
