2 ME. ST. GEORGE MIVAET ON THE 



casts of the interiors of their skulls. A little later. Professor 

 Burt Wilder further elucidated the subject by a paper * giving 

 an account of the cerebrum, with figures, of many varieties of 

 Dogs, as well as of that of Hycena, TTrsus, and Procyon, together 

 with some feline species. In 1880, Julius Krueg t gave forth an 

 elaborate memoir largely on the same subject, by far the most 

 elaborate and complete which has yet appeared, and to which 

 frequent reference will be made. The following year Professor 

 Burt Wilder read before the American Philosophical Society $ an 

 elaborate paper on the brain of the Cat — a paper which has its 

 place on the shelves of our Library. Last of all, Mr. Langley 

 has given us § a very complete paper on the brain of the Dog, 

 wherein will be found || references to yet other memoirs relating 

 to the physiology of the subject and to questions of the cerebral 

 homologies of different orders of mammals — questions with which 

 this paper is not concerned. 



I am not aware of any other works on the subject than those 

 here directly, or, as above, indirectly, referred to ; but there are 

 various isolated descriptions of the brain of different carnivorous 

 mammals, such as those of the late Professor Grarrod and of Pro- 

 fessor Plower, which will be referred to when the subjects they 

 treat of come to be mentioned. Three of these, however, may 

 be referred to at once ^, since in them the two Professors give a 

 short summary of such cerebral characters as they believe to be 

 common to the main subdivisions of the Fissipedal Oarnivora. 



My object in this paper is to point out the leading cerebral 

 characters of many genera of Caruivora, and especially those of 

 certain forms which appear either not to have come under the 

 direct observation of the before-mentioned authors, or not to have 

 had certain characters described which it seems to me desirable 

 to note. I purposely confine myself to the observation of a few 

 characters which I believe to be leading characters, having had
