the great toe, and small ones about the interphalangeäl joints of the 
second toe. The foot presents a very pretty instance of calcaneus 
secundarius forming a part of the anterior end of the articular 
cavity for the head of the talus. The os intercuneiforme rises 
more irregularly than the first one above the surface of the dorsum. 
The length is 8,5 mm, the breadth 5 mm and the depth 4 mm. The 
fossa is much less well-marked than in the other foot and would not 
attract any particular attention. The bone is much less distinctly 
wedge - shaped, the two side surfaces meeting at an angle which seems 
slightly obtuse. Of these surfaces that for the second cuneiform is 
the larger and smoother. It seems not impossible that it was once 
coated with articular cartilage and that a small piece of the bone 
meeting it had similar coating. The side towards the first cuneiform 
is more indefinite and probably had a periosteal covering. 
This specimen is much less satisfactory than the former, in which 
the new bone seems distinctly in its place and makes a small but 
definite part of the foot. This looks more like a quasi - accidental 
ossification. I incline, however, to attribute the same significance 
to both. 
This bone, I repeat, is I believe undescribed; I have a tolerably 
clear recollection of having met with it many years ago. 
Os paracuneiforme. 
Museum number 9390a—10 (Fig. 3). The right foot of a 
white man aged 45 contains both a new bone, paracuneiforme 
and a free calcaneus secundarius with calcaneo- navicular 
coalescence. 
The new bone is situated on the inner surface of the foot in a 
hollow between the scaphoid and the first cuneiform, chiefly in the 
former. It is an elongated boat-like bone, the convexity being free, 
and the greatest diameter nearly ventrical. The length is 16 mm, 
the greatest breadth 8 mm, and the thickness about 2 mm. The 
concavity rests against the scaphoid and the border against the cunei- 
form. The surface points to the possibility that it was once united 
to the scaphoid by cartilage. At least a large part of this bone must 
have been under the tendon of the tibialis anticus. The bones 
of the foot, especially in the mid-tarsal region, present many ir- 
regularities and small outgrowths. There is also much ossification of 
the fibres in the sole of the foot springing from the internal tube- 
rosity of the os calcis. A pathological origin of the ossicle seems, 
therefore, very likely. It bears a striking resemblance to the bone
