NERVES OF MAMMALIA. 175 



ward to divide for the outer side of the second large toe, and the 

 outer small toe ; it sends the deep plantar into the sole to supply 

 the short muscles situated there. The anterior tibial nerve gives 

 branches to the ligaments at the back of the foot, and sends a 

 branch to supply the toe, it, and the inner side of Hi ; the rest of 

 it gives branches to the small muscles on the back of the foot, 

 and then passes forward to join the branch of the peroneal given 

 to the outer side of in, and the inner side of iv ] ; the continua- 

 tion of the peroneal after emerging just above the instep supplier 

 the outer side of its toe, both sides of iv and v, the branch sent 

 to the outer side of Hi and the inner side of iv receiving a branch 

 of the anterior tibial. 



In the order Carnivora, the distribution of the nerves has been 

 described and figured by Swan, in the Fox (liv, p. 150, pi. 33), 

 and in the Jaguar (ib. p. 161 ), from which the following account is 

 chiefly abridged. In the Fox the anterior trunk of the first cervi- 

 cal passes forward, and sends up two filaments to the junction of 

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

 the accessory, and the superior cervical ganglion of the sympathe- 

 tic ; it gives branches to the recti antici, and then joins the descen- 

 dens noni, to be distributed to the sterno-hyoid and ster no-thyroid 

 muscles. The posterior trunk supplies the recti capitis postici 

 and obliqui sup. et inf. The anterior trunks of the second and 

 third cervical nerves give branches to the recti capitis antici, then 

 unite to communicate with the accessory, and divide into branches, 

 which are distributed on the cutaneous muscle and skin at the side 

 of the face and neck and external ear. The fourth cervical gives 

 a branch to join the accessory and others to the trapezius, and is 

 then distributed to the cutaneous muscle and skin at the side of 

 the neck. The fifth cervical nerve gives a branch to the acces- 

 sory, and to the trapezius, and then pierces this to terminate on 

 the skin at the lowest part of the neck. The posterior or dorsal 

 division of the second cervical nerve gives branches to the splenius, 

 complexus, and other muscles, close to the posterior part of the 

 spine, and then sends a branch through the complexus towards 

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

 back of the ear, but is chiefly distributed on the skin of this part. 

 The posterior division of the third cervical is similarly distributed. 

 That of the fourth cervical gives branches to the complexus and 

 other muscles close to the spine, and then terminates on the skin. 

 The posterior divisions of the sixth and seventh also give branches
