THE FOX. 



(CANIS VULPES.) 



1. SUBOCCIPITAL nerve; it emerges from a foramen in the atlas; the anterior 



trunk passes forwards, and sends up two filaments to the junction of the 

 trunk of the par vagum with the glosso-pharyngeal, the ninth, accessory, and 

 the superior cervical ganglion of the sympathetic ; it gives branches to the 

 anterior straight muscles of the head, and then joins the slender descending 

 branch of the ninth, to be distributed on the sterno-hyoid and thyroid 

 muscles ; the posterior trunk terminates on the posterior straight and oblique 

 muscles. 



2. First cervical nerve ; the anterior trunks of the first and second cervical nerves 



give branches to the anterior straight muscles of the head, and then unite to 

 communicate with the accessory, and divide into branches, which are distri- 

 buted on the cutaneous muscle and skin, at the side of the face and neck and 

 external ear. The third gives a branch to join the accessory and others to 

 the trapezius muscle, and is then distributed on the cutaneous muscle and 

 skin at the side of the neck. The fourth gives a branch to the accessory, 

 and to the trapezius muscle, and then pierces this to terminate on the skin at 

 the lowest part of the neck. The posterior trunk of the first cervical nerve 

 gives branches to the splenius, complex, and other muscles, close to the 

 posterior part of the spine, and then sends a branch through the complex 

 towards the occiput, which gives filaments to the muscles inserted into the
