missure or whether they represent the centrifugal fibres found by Cajal 

 in the retina. 



Coronal fibres of the thalamus. Investigation of young mammals 

 shows that these fibres in the main present terminal arborizations in the 

 thalamus. The optic radiations, however, undoubtedly terminate in 

 the cortex, as their cells of origin lie among the ends of the opticus 

 fibres. 



Fasciculus thalauio-mammillaris, s. Vicq d' Azyr. In new born and 

 young mice it was clearly shown that the fibres of this bundle exhibit 

 terminal arborizations in the nidus dorsalis thalami. This bundle, which 

 according to the researches of Gudden has nothing to do with the pil- 

 lars of the fornix, must therefore take its origin in the cells of the cor- 

 pus mammillare — according to Gudden in the caudo-ventral nidus. 



Pedtinculus corporis mammillaris of the rabbit. The fibres of this 

 bundle undoubtedly arise in the large-celled lateral nidus of the corpus 

 mammillare. Of their termini nothing has hitherto been known. The 

 author finds, however, that they end cephalad of the pons in the re- 

 gion of the caudal end of the ganglion intefpedunculare near which 

 they He, surrounding dorsally and in part also penetrating a round nidus 

 already described by Gudden as lying behind the trochlearis nidus in 

 the central grey, the ganglion dorsale tegmenti of KoUiker. Another part 

 of these fibres ends in the central grey which surrounds this nidus. 

 From this nidus and from the central grey around it there arises the 

 dorsal longitudinal bundle of Schiitz which Kolliker has called the dorsal 

 grey longitudinal bundle, and this may be easily followed in longitud- 

 inal sections along the dorsal side of the fourth and third nidi and in a 

 curved course along the floor of the third ventricle. 



Columnae for?iicis of the rabbit. These tracts plainly pass only 

 through the lateral part of the corpus mammillare and end crossed be- 

 hind and on the dorsal side of the latter. The author has followed these 

 fibres to the nidus of the oculo-motorius, the posterior commissure and 

 the nidus ruber, though these relations are not definately established 

 and the real termini he is not at present prepared to state. 



Ganglion Jiabenulae of mammals. The fasciculus of Meynert 

 arises in the ganglion habenulae of the opposite side in free non-med- 

 uUated arborizations. The fasciculus of Meynert contains fine and 

 coarse fibres, of which the latter possibly pass above the ganglion into 

 the pons. In the ganglion interpedunculare arise the medullated fibres 

 discovered by Ganser which pass in two bundles ventro-dorsally and 

 end in the ganglion tegmenti dorsale and in the adjacent central grey. 



Stria medullaris of tJie rabbit. This ends for the most part in the
