branch arose from the n. cutaneus dorsalis intermedialis to supply the 
outer side of the little toe. Variations in the cutaneous nerve supply 
of the dorsum of the foot occurred with the following frequency. 
In 17 instances the n. cutaneus dorsalis lateralis (external saphenous) 
supplied the place of the n. cutaneus dorsalis intermedius and sent 
branches to the contiguous sides of the 4th and 5th, and 3d and 4th 
toes. In two instances a branch from the n. cutaneus dorsalis lateralis 
anastomosed with the n. cutaneus dorsalis intermedialis and the com- 
bined nerve then divided into branches for the contiguous sides of the 
4th and 5th, 3d and 4th, and 2d and 3d toes. With the branch to the 
last a ramus from the n. cutaneus dorsalis medialis anastomosed. In 
15 instances a branch from the n. cutaneus dorsalis lateralis anastomosed 
with one from the n. cutaneus dorsalis intermedius and the branches 
arising from the combined nerve suppled the contiguous sides of the 
3d and 4th, and 4th and 5th toes. In two instances the n. cutaneus 
dorsalis lateralis sent a branch to anastomose with one from the n. 
cutaneus dorsalis intermedialis going to the 2d and 3d toes. In five 
instances the n. cutaneus dorsalis lateralis supplied the outer side of 
the little toe and the contiguous sides of the 4th and 5th toes. In 10 
instances a branch from the n. cutaneus dorsalis lateralis anastomosed’ 
with the branch from the nm. cutaneus dorsalis intermedialis sent to 
supply the contiguous sides of the 4th and 5th toes. In four instances 
the n. cutaneus dorsalis intermedialis supplied the contiguous sides of 
the 2d and 3d, 3d and 4th, and 4th and 5th toes while the n. cutaneus 
dorsalis medialis supplied the outer side of the first toe and aided in 
the supply of the contiguous sides of the Ist and 2d toes. In one of 
these instances the n. cutaneus dorsalis medialis arose in the leg from 
the n. peroneus profundus. In five other instances the nerve distribu- 
tion was similar in nature but an anastomotic branch passed from the 
n. cutaneus dorsalis medialis to the nerve going to supply the contigu- 
ous sides of the 2d and 3d toes. In one of these instances the n. cuta- 
neus dorsalis medialis arose from the n. peroneus profundus nerve and 
emerged from between the peroneus tertius and the extensor digitorum 
longus muscles. In two instances the n. cutaneus dorsalis medialis sup- 
plied, in addition to its usual territory, the contiguous sides of the 3d 
and 4th toes; the n. cutaneus dorsalis intermedialis was confined in 
distribution to the 4th and 5th toes. In one instance the n. peroneus 
profundus supplied in addition to its usual branches, the chief branches 
to the medial side of the great toe and the lateral side of the 2d toe.
