the brain involves the removal of difficulties varying in kind and 

 degree. These several categories of difficulties should be at- 

 tacked separately and in the order of (i) their fundamental im- 

 portance and (2) their simplicity." — Idem (55, 145)- 



A. Van Gehuchten says (32, p. 32): " Les sillons les 

 plus profonds des deux faces du cervelet, ainsi qui les lobules 

 qu' ils delimitent, ontrecu des noms particuliers. Mais nos con- 

 naissances de la structure et surtout des fonctions du cervelet 

 sont encore si incompletes que, dans I'etat actuel de la science, 

 cette division et cette homenclature n'ont guere d'importance. 



Alfred Schaper (28, p. 493) thinks, from his investiga- 

 tions of the brains of teleosts, that present statements con- 

 cerning the development of the cerebellum are incorrect and 

 that further investigations should be made. 



" In descriptive anatomy an astounding variety of names 

 are applied to the various parts of each lobe of the cerebellum ; 

 it would be an essential gain if at least three fourths of these 

 names could be discarded." — Charles Sedgwick Minot (23, 674). 

 To this the writer would add that, whatever the structure 

 of the cerebellum may be, its terminology must be such that an 

 accurate description of it can be written. 



And further, that numerous instances, in standard litera- 

 ture, can be cited where descriptions and figures of brains are 

 incorrect or incomplete, due in some cases, as remarked by 

 B. G. Wilder (35) to,— 



[. "Injuries in removal, — by which the appendicular 

 lobes, hypophysis, olfactory bulbs, have been torn off and left 

 in the skull, telas and other delicate parts of the brain have 

 been ruptured " so as to convey the impression of openings 

 which did not exist in nature. 



2. Failure of the artist to comprehend morphological de- 

 tails. Anatomical drawings to be useful, ought always to be 

 made from carefully prepared specimens, by some one who has 

 at least a good working knowledge of the general anatomy of 

 the parts concerned. 



"It (the cerebellum) must be considered as a compages 

 having throughout, from centre to innermost recess, connection
