(2) Eami digitate* doraale* to the adjacent sides of the first and 

 second toes. 



(3) Branches to the J/J/. extenzore* digiti II. 



(4) The inner, terminal branch (Fig. 130 A] at once divides : 

 (a) The outer branch runs between the third and fourth toes as 



far as the commencement of the web, where it bifurcates to form 

 two Tiami cvtanei, which course along the adjacent sides of these 

 toes as far as their apices. 



() The inner branch passes to the extensor muscle, and, in part, 

 to the adjacent sides of the third and fourth toes. 



(5) The outer, terminal branch (Fig. 130 B] of the X. peroneus 

 commv.ni* inferior passes to the muscles of the fourth and fifth toes, 

 and supplies Kami cv.tanei dormles to the outer side of the fourth 

 and inner side of the fifth toes. 



Cutaneous branches of the 3 . titiaH* supply the outer side of the 

 fifth and inner side of the first toe. 



G. THE SYMPATHETIC SYSTEM (Sympatfau*). 

 (Re-icritten by the translator.) 



The sympathetic cord or chain is a row of nervous ganglia 

 (vertebral or lateral ganglia), connected by nerve-fibres, and lying 

 on either side of the vertebral column (Figs. 117 and 131); with 

 the exception of the last spinal nerve there is usually one sympa- 

 thetic ganglion associated with each spinal nerve ; in the case of the 

 tenth spinal nerve there may be only one ganglion or as many 

 as twelve. 



The first ganglion (Figs, in, opposite ics; 117 Si) is placed on 

 the hypoglossal nerve just as it emerges from the first intervertebral 

 foramen ; it is large, but smaller than the second ; its Ramvs 

 commnnicans is represented by several fine and very short fibres, 

 which connect the ganglion with the nerve. This ganglion is con- 

 nected with the second by two cr three nervous threads, between 

 which passes the subclavian artery, a true Anuulu* Tieussenii being 

 thus formed (de TVatteville). The other ganglia are connected by 

 single bands of fibres. The first ganglion supplies also branches to 

 the axillary artery and to the cardiac plexus. 



The second ganglion (Figs. 117 and 131) is the largest, and is 

 closely applied to the brachial nerve ; as in the case of the first 

 ganglion and hypoglossal nerve, it is attached to the second spinal 

 nerve without a distinctly marked Itamus communicant.
