A HISTORY OF SCIENCE 



have made his mark in art quite as definitely as he has 

 made it in science. Indeed, even as the case stands, 

 his draughtsman's skill has been more than a mere 

 recreation to him, for without his beautiful drawings, 

 often made and reproduced in color, his classical mono- 

 graphs on various orders of living creatures would have 

 lacked much of their present value. 



Moreover, quite aside from these merely technical 

 drawings, Professor Haeckel has made hundreds of 

 paintings purely for recreation and the love of it, illus- 

 trating and that too often with true artistic feeling 

 for both form and color the various lands to which 

 his zoological quests have carried him, such as Sicily, 

 the Canaries, Egypt, and India. From India alone, 

 after a four-months' visit, Professor Haeckel brought 

 back two hundred fair-sized water-colors, a feat which 

 speaks at once for his love of art and his amazing in- 

 dustry. 



I dwell upon this phase of Professor Haeckel's char- 

 acter and temperament from the very outset because 

 I wish it constantly to be borne in mind, in connection 

 with some of the doctrines to be mentioned presently, 

 that here we have to do with no dry-as-dust scientist, 

 cold and soulless, but with a broad, versatile, imagina- 

 tive mind, one that links the scientific and the artistic 

 temperaments in rarest measure. Charles Darwin, 

 with whose name the name of Haeckel will always be 

 linked, told with regret that in his later years he had 

 become so steeped in scientific facts that he had lost 

 all love for or appreciation of art or music. There has 

 been no such mental warping and atrophy in the mind 

 of Ernst Haeckel. Yet there is probably no man liv-
