EXPLANATION OF FIGURES 
122 Transection through the corpus mammillare. Weigert method. > 17. 
123 Diagram showing the two parts of the right olfactory nerve, and the rela- 
tions of their fibers to the cells of the bulb and to the fibers of the olfactory tract. 
124 Diagram of a horizontal projection of the right olfactory bulb showing the 
connections, in the bulb, of the different tracts of the crura. 
corp. mam. (G), corpus mammillare (of Goldstein); fasc. retr., fasciculus 
retroflexus; fil. olf., filaolfactoria; g.n.term., ganglion cell of the nervus terminalis; 
gran. cell, granule cell of the nucleus olfactorius anterior; mitr. cell, mitral cell; 
nucl. chl. hyp., nucleus cerebellaris hypothalami; nucl. dif. lob. lat., nucleus dif- 
fusus lobi lateralis; n. olf. ant., nucleus olfactorius anterior; 7. olf. lat., nervus ol- 
factorius lateralis, consisting largely of fibers from the lamellae of the caudal and 
lateral portion of the olfactory capsule; n. olf. med., nervus olfactorius medialis, 
formed largely from fibers originating chiefly in the rostral and medial portion of 
the capsule; n.term.,nervusterminalis; nucl. prerot., nucleus prerotundus ;nucl. rot., 
nucleus rotundus; nucl. subrot., nucleus subrotundus;s. mam., sulcus mammillaris; 
tr. cbl. tect., tractus cerebello-tectalis; tr. olf. asc., tractus olfactorius ascendens, 
composed of centrifugal fibers from the corpus precommissurale, pars medianus; 
tr. olf. asc., pars lat., tractus olfactorius ascendens pars lateralis; tr. olf. 
asc., pars med., tractus olfactorius ascendens, pars medialis; tr. olf. lat., trac- 
tus olfactorius lateralis, composed of the following three tracts, all centri- 
petal, and practically all terminating, in the carp, in the nucleus olfactorius 
dorsalis and nucleus pyriformis of the same side; fr. olf. lat., pars. intermed., trac- 
tus olfactorius lateralis, pars intermedia; tr. olf. lat., pars lat., tractus olfactorius 
lateralis, pars lateralis; tr. olf. lat., pars med., tractus olfactorius lateralis, pars 
medialis; tr. olf. med., tractus olfactorius medialis, the mesal part of the medial 
olfactory radix of authors, divided into the following; tr. olf. med., pars lat., 
tractus olfactorius medialis, pars lateralis, terminating, after decussation in the 
anterior commissure, in the nucleus pyriformis of the opposite side; tr. olf. med., 
pars med., tractus olfactorius medialis, pars medialis, forming the commissura 
interbulbaris of most authors which, as indicated in figs. 136 and 138, is largely 
a decussation and not a commissure; tr. thal. sp., tractus thalamo-spinalis 
(Kappers).
