J O H N FRANKLIN I-IUBER THE ARRANGEMENT CONSIDERED AS A WHOLE I n describing the results of this investigation, attention will be given first to the arrangement of arteries as a whole and then to the individual vessels.
The standard description of a dorsalis pedis artery first giving off lateral and medial tarsal branches, next, at about the level of the first tarsometatarsal joint, an arcuate artery with second, third and fourth dorsal metatarsal branches, and then a first dorsal metatarsal artery, with each of the dorsal metatarsal arteries dividing into two dorsal digitals, was found in only eleven of the 200 feet dissected. However there was no other arrangement which was present in more than nine instances. Of three such, one differed from the "standard" principally in that the arcuate arose at about the level of the cuneonavicular articulation ; another differed principally in that the fourth dorsal metatarsal did not give off dorsal digitals, these coming instead form the plantar aspect; and the third differed in that the fourth dorsal metatarsal was absent, the dorsal digitals coming again from the plantar aspect.
I n addition to the four types just described, there were some seventy to eighty others (depending on the interpretation) present in from one to eight instances each, differing from one another in varying degrees. No attempt will be made to describe, or even tabulate all of these individual arrangements, but some idea concerning them can be gained by grouping them in the following manner : A. Arcuate artery arising a t about the level of the first tarsometatarsal joint and giving rise to (1) the second, third and fourth dorsal metatarsals; (2) the second and third dorsal metatarsals; and (3) only the second dorsal metatarsal. B. Arcuate artery arising at about the level of the naviculocuneiform joint. (Subgroups 1, 2 and 3, the same as under A.) C. No arcuate artery present. D. Dorsalis pedis artery practically absent.
