serted, one on the slip to the third and two on the slip to the fourth 
toe. This arrangement was constant, the little slips presenting no 
variation in number or proportions. The two to the tendon of the 
fourth toe were inserted about one-fourth of an inch apart. 
Tibialis posticus; Plate XVI, Figs. 5 and 8, T. P 
The Tibialis posticus arises from the proximal ends of the tibia 
and fibula, as stated by Dr. Allen, but the origin from the tibia 
extends over half way down the shaft, lying just laterad to the 
origin of the flexor longus digitorum with which it 1s closely con- 
nected. This muscle also arises largely from adjoining fascia, 
especially of the flexor longus hallucis. Its tendon is wholly con- 
cealed by the flexor longus digitorum, in company with which it 
passes through a sheath behind the internal malleolus, but in a 
separate compartment, and is inserted on the plantar surface of 
the scaphoid. 
Peroneus longus; Plate XIV, Per. lon.; Plate XVI, Figs. 5 and 7, P. 1. 
The insertion of this muscle, as given by Dr. Allen, is very dif- 
ferent from what I found. (See p. 139 of his paper.) In my 
specimens the carneous fibers converge to a round tendon. This 
tendon passes through a sheath behind the highest tubercle on the 
external malleolus, and superficial to the tendons of the other 
peroneals, to a loop behind the prominent tubercle on the anterior 
part of the lateral surface of the os calcis. From this point its 
direction corresponds to the long axis of the foot, until it enters 
the deep groove in the anterior part of the plantar surface of the 
cuboid, thence the tendon passes obliquely across the foot to be 
inserted into the outside of the base of the first metatarsal. This 
insertion of the peroneus longus is practically the same as is found 
in man and the cat, and did not vary in the specimens examined 
by the author. 
Peroneus brevis; Plate XIV, Per. Brev.; Plate XVI, Figs. 5, 6 and 7, P. Br. 
The origin of this muscle occupies not only the middle third of 
the fibula but extends nearly to the malleolus. The tendon of 
insertion appears on the lateral surface of the muscle an inch be- 
low the origin, but receives carneous fibers down to the external 
malleolus, where, thick and strong, it passes through a deep groove 
on the posterior surface, thence beneath the peroneus longus, to be 
inserted into the lateral aspect of the base of the fifth metatarsal; 
and in some cases into the dorsal and plantar fascia.
