CARL GEGEXBAUR. 791 



On the recommendation of Gegenbaur, Ernst Haeckel was also 

 appointed a private instrnctor in Jena. J^etween these two natural- 

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

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

 firm friendship, which is testified to in glowing words by Haeclcel in 

 the introduction to his General Morpholog}^ 



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 zoolog}', and being prepared by them in various ways 

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



Although united by man}^ bonds to Jena, Gegenbaur, though onh' 

 after long hesitation, accepted the call to Heidelberg as successor of 

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

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

 established university at Strassburg, were declined. He possessed, 

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

 course of instruction in a magnificently equipped university, which in 

 the more 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 Avas in all respects an admirable man, Avho 

 quickly gained the loA'e and respect of all Avith Avhom he became in 

 any Avise intimately associated. Resolute and uninfluenced by super- 

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

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

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

 evincing a warm and generous appreciation of the beautiful things in 

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

 avoid social gatherings, and only occasionally attended congresses and 

 scientific meetings. Easily re})elled b}^ strangers, and at times per- 

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

 Avhich often shoAved itself in most unexpected Avays to those intimately 

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

 to him Avith rare love and deA'otion. and under his leadership felt 

 themselves firmly bound to his school of morphology.
