from the anterior bundle is joined by one from the posterior, and passes forward to the 

 muscles and skin on the anterior part of the spine ; the other branch of the anterior 

 bundle, after it has communicated with the posterior branch passing forward, passes 

 backward, and is joined by the second branch of the next posterior bundle, to terminate 

 on the muscles and skin on the posterior part of the spine. Neither of the branches of 

 the posterior bundle forms a ganglion. 



The same disposition of the spinal nerves is continued to within a short distance 

 from the tail, when the whole of each anterior and posterior bundle becomes joined, and 

 the division into branches for the muscles and skin, on the anterior and posterior parts 

 of the spine, takes place. The spinal cord terminates in a bulb near the tail.
