We are unable to agree with some of the remarks .of 
Stannius on the sympathetic of the Plaice. He states that 
the first cranial ganglion is that connected with the facial 
nerve, that there is no ganglion corresponding to the 
glossopharyngeus, and that the rami communicantes for 
the first 3 or 4 spinal nerves arise from a common ganglion 
also giving origin to the NN. splanchnici. We have not 
examined the sympathetic posteriorly, but Stannius states 
that there are very large sympathetic nerves connected by 
a commissure perforating the kidney to reach the repro- 
ductive organs. They also pass backwards with the ovary 
or testis into the cavity between the skeleton and the skin 
formerly supposed to be the posterior extension of the 
body cavity. 
The sympathetic nervous system of Fishes has 
recently been investigated in some detail by Jaquet* and 
C. K. Hoffmannt+t—the former studying its anatomy and 
the latter its development. Jaquet divides it into cephalic, 
abdominal and caudal portions. The first is stated to be 
connected with the ganglia of five cranial nerves—the 
“hypoglossal ”’ [first spinal], vagus, glossopharyngeus, 
facialis and trigeminus, and fibres from the second and 
third ganglia are said to accompany the glossopharyngeal 
to the pseudobranch. Jaquet’s work contains a formal 
scheme of the Teleostean sympathetic (fig. 4), and also 
many statements which are not borne out by our examina- 
tion of the Plaice, and which seem to us to require con- 
firmation. The most important work on the anatomy of 
the sympathetic in bony fishes is that of Chevrel,f who 
investigated the relation of the ganglia to those of the 
cranial nerves, and who asserts that the first sympathetic
