anastomosis. On leaving the latter it bears another 
moderate-sized ganglion (4), but no fibres were seen to be 
exchanged between any of these ganglia and the glosso- 
pharyngeus nerve. In front of ganglion 4, the cord rises 
upwards and becomes attached to the Truncus hyoman- 
dibularis, just as the latter emerges from the skull, the 
post-trematicus vii. lying below it. It now passes into 
the cranial cavity through the jugular foramen, and is 
so closely pressed against the T. hyomandibularis that we 
were unable to determine whether fibres were exchanged 
or not, although we believe not. Inside the cranium, it 
bears the small ganglion 3, from which the ganglionated 
intracranial most anterior commissure (3”) arises. The 
commissural ganglion is situated actually on the root of 
the sixth cranial nerve. 
From section 536 to 494 the cranial sympathetic 
accompanies the R. palatinus facialis, and is very closely 
attached to it. In front, it passes through the trigemino- 
facial foramen, and takes up a position between the skull 
and the origins of the maxillary and mandibular v. nerves. 
It now swells into the large ganglion 2, from which a very 
prominent R. communicans (com. v.') passes upwards to 
the T. maxillo-mandibularis. The first cranial ganglion 
(1) les above the second, and is connected with it by a 
very short strand of fibres. Both the first and second 
ganglia give off a cord in front, but the two unite before 
reaching the ciliary ganglion. ‘The first ganghon also 
gives off a nerve internally, which accompanies the ventral 
edge of the R. ophthalmicus superficialis v. The possibly 
corresponding nerve of the other side arises externally 
from the second ganglion, accompanies the superior 
maxillary v., and has a very small ganglion of its own. 
From the first cranial ganglion onwards the sym- 
pathetic is accompanied by the profundus nerve. They
