larger scale, although from the same series 
of sections. ‘lhe nerve ramuli in front are a 
little diagrammatic, in order that they may 
be shown more clearly. viii., auditory 
nerve. The reconstruction applies also to 
the adult ear, but the relative sizes of the 
parts are of course different. 
Fig. 25. Reconstruction of the right and left nasal 
organs seen from above. Drawn to exactly 
twice the scale of figs. 23 and 26, and from 
the same series of sections. The disposition 
of the accessory secretory chambers is 
slightly diagrammatic for the sake of clear- 
ness. The termination of the olfactory 
nerves is not shown for the same reason. 
Fig. 26. The sympathetic nervous system seen from 
. above, and plotted from the same series of 
sections and to the same scale as fig. 23. 
The dotted line represents the median line 
of the body continued straight forwards. 
The figure is diagrammatic in four respects: 
(1) the eeliac ganglion lies directly under 
ganglion 2; (2) the first cranial ganglion 
hes immediately over the second on the 
ocular side; (3) the ocular ciliary ganglion 
les over the third nerve; (4) the eyeless 
ciliary ganglion is external to the oculo- 
motorius. The cranial ganglia are numbered 
1-8, the spinal l’/-7’. ii. is the Nervus 
oculomotorius, after it has given off the 
nerve to the M. rectus superior.
