PROFESSOR LE CONTE'S ESTIMATE OF DANA 



Professor Joseph Le Conte's Estimate of Dana as a Geologist Corals, 

 Cephalization, and Volcanism Development of the Earth as a Unit 

 Continental Ice-Sheet. 



THE author of this memoir is not qualified to speak 

 with authority in respect to the contributions of 

 Professor Dana to the science that he most loved, and 

 fortunately there is no reason for him to make the at- 

 tempt. Many highly qualified men have made the 

 desired reviews, and among them Professor Joseph Le 

 Conte, of the University of California, spoke as follows 

 before the American Society of Geologists soon after 

 Mr. Dana's death. This address is so admirable in style, 

 and so appreciative in spirit, that its principal paragraphs 

 will be given to the reader.

Dana's Comprehensive Mind 



There are few, very few, men (and becoming fewer

 as did Dana. He became the highest living authority in 

 mineralogy, in several departments of zoology, as, for 

 example, Crustacea and zoophytes, and, more than all, 

 in geology. Of some two hundred and odd scientific 

 papers contributed by him, more than one-half were on 

 geology. Not only in the three sciences mentioned above
