CARL GEGENBAUR. 791 



On the reconimendation of Gegenbaur, Ernst Ilaeckel was also 

 appointed a private instructor in Jena. Between these two natural- 

 ists, Avorking- along- the same lines, each in his own way as an ener- 

 getic promoter of Darwin's new doctrine of evolution, there grew a 

 lirm friendship, which is testified to in glowing words by Ilaeckel in 

 the introduction to his General Morphology. 



In Jena the writer had the good fortune, as a student in the first 

 medical semester, to become somewhat intimately acquainted with 

 these two closely associated great naturalists, receiving instructions 

 in anatomy and zoology, and being prepared by them in various ways 

 for his later vocation, for which aid he will ever feel thankful. 



Although united by many bonds to Jena, Gegenbaur, though only 

 after long hesitation, accepted the call to lleidel])erg as successor of 

 Arnold (1873). '' It carried him to the south, whence he had come." 

 Other calls Avhich followed later, to Amsterdam and to the newly- 

 established university at Strassburg, were declined. He possessed, 

 however, in Heidelberg everything that he could wish — a limited 

 course of instruction in a magnificently equipped university, which in 

 the nwre congenial southern part of Germany gave him leisure for 

 uninterrupted progressive scientific work; and in his own home a 

 happy family life which came from his marriage in Jena, after the 

 death of his first wife, to the daughter of the anatomist Arnold. 



The great naturalist was in all respects an admirable man, who 

 quickly gained the love and respect of all with whom he became in 

 any wise intimately associated. Resolute and uninfluenced by super- 

 ficial things, he held firml}' to that which he had by close scrutiny 

 found to be true and just. Exacting with himself and others, he 

 sought in close application to his work the happiness of life. Though 

 evincing a warm and generous appreciation of the beautiful things in 

 nature and art. he was naturally of a retiring disposition, inclined to 

 avoid social gatherings, and only occasionally attended congresses and 

 scientific meetings. Easily repelled by strangers, and at times per- 

 haps harsh and inconsiderate, yet he possessed a sympathetic spirit, 

 which often showed itself in most unexpected ways to those intimately 

 known to him. For this reason, Gegenbaur's assistants Avere attached 

 to him with rare love and devotion, and under his leadership felt 

 themselves firmly bound to his school of morphology.
