It is worthy of note that after the disappearance of both vagus 

 niduli there remains a strong tract continuing the glossopharyrngeal 

 root dorso-mesad of the dorsal end of the raphe It may correspond 

 to that part of the glossopharynt-eal which has its centre in the gang- 

 lion, since after the removal of the glossopharyngeal ganglion it suffers 

 the same alterations as the corresponding tract of the vagus after the 

 removal of that ganglion. 



There is no sharp boundary between the glossopharyngeal and 

 the vagus in most cases. There is no separate nidulus which 

 sends its fibers to the glossopharyngeal alone. On the other hand 

 experiments suggest that the cephalic part of the vagus nidulus sends 

 Its fibres to the glossopharyngeal, for when the vagus alone was ex- 

 tirpated these cells were altered much less than those of the caudal 

 part, while if both vagus and glossopharyngeal were extirpated these 

 cells were affected like the others. 



That portion of the funiculus solitarius which does not enter the 

 glossopharyngeal goes forward to enter the sensory root of the trigem- 

 inal. No part of this bundle has been observed to pass farther 

 cephalad in birds. Probably some of its fibers enter the acusticus. 

 After extirpation of the glossopharyngeal audits ganglion, degener- 

 ation of the solitarius of the same side could be followed down to its 

 crossing, though beyond that point it is very obscure. The portion 

 passing to the fifth was not affected. [ C. Judson Herrick. ] 



Dr. Berkley on the Cerebellum. 



In the notice of Dr. Berkley's Paper on the Cerebellum of the 

 Dog in the Johns Hopkins Hospital Reports, Vol. Ill, which ap- 

 peared early in 1893, the reviewer failed to observe that the paper 

 was prepared in March, 1891, which sufficiently explains the absence 

 of reference to the important papers of Koelliker, etc. We are glad 

 to learn that a supplementary paper by Dr. Berkley is soon to appear.
