indefinite. The metatarsal arterj- is sometimes absent, and when this occurs 

 the dorsal interosseous arteries of the outer three interosseous spaces are 

 usually furnished by the three posterior perforating arteries from the plantar 

 arch, or, it may be, by the tarsal artery. 



Dorsalis Pedis Nerve.— This nen-e is the continuation of the 

 anterior tibial. It commences at the anterior hgament of the 

 ankle-joint, and terminates at the distal end of the first inter- 

 osseous space by dividing into two dorsal collateral digital nerves

 artery, on the outer side of which it lies, with the inter\^ention of the

 of the first interosseous space it is reinforced by an offset from the 

 inner branch of the internal division of the musculo-cutaneous
