the second time in 1893 he expected to begin that work of cor- 

 relation, and this is doubtless the special significance of the an- 

 nouncement published at that time of a text-book on compara- 

 tive neurology. But this period of work he was not able to 

 enter far and the text-book is still unpublished. This manu- 

 script, together with that of several other projected works on 

 psychology and ethics, remains. It is yet too early to state 

 how much of this matter can be edited for publication. If the 

 last ten years of his life could have been spent in Granville, as 

 was his plan, results of moment in the way of correlation would 

 undoubtedly have followed. As it is, none of the papers in neu- 

 rological lines were regarded by him as other than fragments. 



The first important paper in neurology was published in 

 the Journal of the Cincinnati Society of Natural History — "Notes 

 upon the Brain of the Alligator." This is an elaborate descrip- 

 tive article illustrated with nearly a hundred of the beautiful 

 pen drawings which he used so freely in all of his work. 



The second neurological paper of special importance was 

 the leading article in the first issue of this Journal, on the his- 

 togenesis of the cerebellum in correlation with its comparative 

 anatomy. This paper was ignored largely by the workers im- 

 mediately following, but its main points have been fully con- 

 firmed by later students. It is really, though very brief, one of 

 his best contributions. 



Of the remaining neurological papers, the most important 

 were published in this Journal, those in the Anatotniuker An- 

 zeiger, American Naturalist, etc., being for the most part sum- 

 maries of the longer articles. These were descriptive articles, 

 in most cases, devoted mainly to the brains of fishes and 

 reptiles, with some atrention to amphibians. 



The greater part of his descriptions of the fish brain have 

 since been worked over with the same sections which he used 

 in hand, and his descriptions have been found to be very exact, 

 though often so brief as to make it difficult to understand them 

 without reference to the preparations. Furthermore they stand 

 the test of control by the more recent neurological methods 

 very well, though of course not always in detail. His method
