5i8 Journal of Comparative Neurology and Psychology. 



sophic insight and the fearless way in which he disclosed his 

 profoundest thinking to the least initiated of his pupils. The 

 ability to do this without befogging the air was an exceedingly 

 rare gift and was stimulating even to a dullard. He knew the 

 philosophical classics thoroughly from original sources and the 

 trend of his thinking was very early foreshadowed in the trans- 

 lation of Lotze's Outlines of Psychology published in 1885 in 

 Minneapolis, with his own appended chapter on the structure of 

 the nervous system. 



Upon his removal to the University of Cincinnati in 1889, 

 with which the third period of his life may be said to begin, 

 the geological studies with which the preceding five years had 

 been so fully occupied were summarily brought to a close and 

 he threw himself with renewed energy into the study of the 

 nervous system. Extensive papers on the brains of different 

 animals appeared in rapid succession, of which the most valu- 

 able are two series, one on the brains of various fishes, the 

 other on those of reptiles. In 1891 the Journal of Comparative 

 Neurology was founded and served as the medium of publication 

 for most of these researches. The founding of this Journal 

 can best be designated as a piece of characteristic audacity. It 

 was a purely private enterprise, with no fund to defray the ex- 

 penses and very little outside cooperation promised. But with- 

 out counting the cose he plunged boldly in, expecting a con- 

 stiuency to be developed as the work went on. In this he has 

 not been disappointed, though recognition of financial needs has 

 lagged sadly behind that of the scientific value of the Journal. 



At the close of 1891 he resigned his chair in the Univer- 

 sity of Cincinnati to accept a chair of biology in the University 

 of Chicago, then being reorganized. The early part of 1892 

 was spent in Europe, chiefly Berlin. Upon his return the ad- 

 justment at the University of Chicago presented unexpected 

 difficulties and after a series of misunderstandings he finally 

 withdrew from that institution, declining an offer to return to 

 Germany for further study on full salary. He was im- 

 mediately elected to his old post in Denison University with 

 an assistant and the privilege of devoting only a part of his
