brates, and for the New Jersey Survey prepared his extensive mono- 

 graphs on the Cretaceous fossils. 



Personally Professor Whitfield had a pleasing manner, and his long 

 experience with his science and its devotees in this country for more than 

 half a century gave him a fund of reminiscence specially interesting to 

 the younger men. Conscientious in his devotion to his duties, gifted 

 with one of those extraordinary memories for places, dates, details, records 

 and literature which seem to pertain to a distinct category, always careful 

 in safeguarding a never rugged body, he outlived all the contemporaries 

 of his early work, reached the close of his life with comparative freedom 

 from illness and bodily suffering, and left behind a record of permanent 

 achievement and essential progress in his science.
