The part corresponding to the cuboid has a separate bony nucleus, 
smaller than the nucleus of the os calcis.. Of the first row, the 
astragalus is fused with the os calcis, and the scaphoid is wanting 
or fused with the astragalus. 
Muscites.—The Flexor Brevis Digitorum sends tendons to the 
two lesser toes, that to the external being much the largest. The 
Flexor Longus Digitorum and Flexor Longus Pollicis are separate 
muscles in the leg, but at the ancle form a common tendon, which 
at the middle of the foot, after receiving a large accessorius, divides 
into two, one for the great toe, the other for the second toe, which 
perforates the tendon of the short flexor. There is one Lwmbro- 
calis, arising from both sides of the long tendon to the second toe, 
and going to the tibial side of the same toe. Two muscular bundles 
arise from the abductor minimi digiti, besides the usual tendon of 
that muscle, and proceed one to the fibular side of the second toe, 
the other to the tibial side of the outer toe. They are like large 
lumbricales, or additional short flexors. The Flexor Brevis Minima 
Digiti is wanting, There are two plantar Interosser, one for the 
tibial side of each of the two lesser toes; and one dorsal, in the 
outer space, for the middle toe. 
Katensors.—The Haxtensor Brevis Digitorum, gives five distinct 
digital tendons, three to the middle toe, one of which is larger than 
the tendon to the outer or to the great toe. All of the five come, 
as usual with the tendons of this muscle, from separate portions of 
the muscle. A sixth portion and tendon passes to the external 
metatarsal bone, and here represents the peroneus tertius, which is 
wanting in its usual situation. The Hatensor Longus Digitorwm is 
small, and gives at the ancle a tendon to join the extensor longus 
pollicis, the rest of the tendon ending on the os calcis. It is just 
possible that an intra-uterine fracture of the tibia which had taken 
place, with angular union, may account for the atrophy of this 
muscle, but the other muscles of the leg are well formed. The 
Katensor Longus Pollicis is large and separate throughout, except 
that it receives a tendon from the extensor longus digitorum. 
The muscles not alluded to in these notes present their usual 
arrangement. 
Nerves.— The distribution of the plantar digital nerves is some- 
what remarkable. The external plantar sends a nerve to the fibular 
side of the outer toe, and a second to both sides of the outer inter- 
digital cleft. The internal plantar, which has the usual prepon- 
derance in size, sends, first, a nerve for the tibial side of the great 
toe; second, a branch to the internal cleft which gives off first one 
and then a second set of subdivisions to the sides of the cleft, the 
double nerve on each side keeping a plantar course; third, a branch 
to join with the external plantar in supplying both sides of the 
outer cleft. Also there is a twig from the deep or muscular divi- 
sion of the external plantar, through below the flexor brevis digi- 
torum muscle, to join one of the branches of the internal plantar to 
the fibular side of the great toe. A similarly derived and similarly
