kidney after a very short course. Of the three others two 
join to form the dorsal Nervus splanchnicus (n. sp.') lying 
over the above artery, but before joining one of them 
gives off a thin twig which accompanies the cesophageal 
artery. The fourth branch, after giving off a fine twig 
to the kidney, becomes the ventral N. splanchnicus 
(n. sp."), lying under the artery. The latter nerve is for 
some part of its course opposed to the R. intestinalis of 
the vagus. When the coeliaco-mesenteric artery divides 
into a dorsal coeliac and a ventral mesenteric artery, the 
two RR. splanchnici also divide (ep. figure). 
From the first spinal sympathetic ganglion (1’) three 
nerves arise. One of these is certainly, and another pos- 
sibly, a R. communicans to the ventral ramus of the first 
spinal nerve (com. 1). The third seemed to enter the 
jugular ganglion of the vagus, but this is not certain. 
From sections 730 to 704 the cord is attached to the inner 
surface of the root and ganglion of the Truncus branchialis 
primus N. vagi, but as far as could be ascertained 
exchanged no fibres with it. The first spinal sympathetic 
ganglion occupies an intermediate position between the 
cranial and spinal sections of the cord, since it is con- 
nected both with the vagus and first spinal nerve. 
After leaving the first spinal ganglion, the cord is 
continued forwards as the cranial sympathetic, and from 
section 702 to 678 accompanies the superior jugular vein, 
during which it bears a very small ganglion (8). After 
leaving this vein it bears ganglion 7 and becomes attached 
io the inner surface of the glossopharyngeus ganglion and 
trunk (658-620), being wedged in between the latter and 
the skull, and bearing ganglion 6. In front again, when 
the glossopharyngeus splits up, it accompanies the ventral 
edge of Jacobson’s anastomosis (618-560), and swells into 
a very large ganglion (5) very closely related to Jacehson’s
