90 Dr John Struthers on Variation in the Number 
of the other foot. The fifth and sixth toes have each only two 
phalanges; the proximal phalanges are close together, but can be 
made to move past each other, Digital variety is unknown in the 
family on either side. R L is one of nine children, three 
boys and six girls. The father’s family have, as usual with the 
Newhaven fishermen, always been in Newhaven. The grandmother 
came from the Highlands, and never knew of such a thing on her 
side of the family. Both the father and mother have brothers and 
sisters in Newhaven, all with families of sons and daughters. The 
mother states that her father’s left little toe grew very awkwardly 
across the others, not in consequence of the pressure of the shoe, 
but naturally. 
A friend showed me the other day a peculiar curve of his little 
finger, which two of his brothers also have. His father’s mother 
had exactly the same peculiarity; also some of the children of a 
paternal uncle. 
14. Case in which one Hand presents Seven or Hight Digits, forming 
an approach to the condition of Double Hand. 
G-— 8 , et. 5, has seven digits on the left hand, and the 
one corresponding to the thumb double at its distal segment, con- 
stituting so far an eighth digit. In every other respect the boy is 
well formed. ‘The appearance presented by the hand is seen in fig. 
4. There are seven distinct metacarpal bones. The four fingers 
on the outer side present the usual form and proportionate length, 
each with its three phalanges. The fifth has the position and 
opposing action of the thumb. Besides the metacarpal bone, it has 
two segments, the distal of which contains two phalanges placed 
side by side, while the proximal phalanx is single. The twin distal 
phalanges can be made to move a little past each other, and the 
one to the inner or radial side ends partly by a prominent non- 
articular angle, as if its proximal phalanx were wanting. They 
are closely enveloped in a common integument, and their nails 
join at their contiguous edges. He moves the thumb indepen- 
dently and freely, so that all its tendons must be separate from 
those of the digits on either side. The sixth and seventh digits 
are like the ring and little fingers of a right hand, except that the 
little finger is proportionately small. Hach has three phalanges, and 
they are webbed most of the way between the proximal phalanges. — 
Their metacarpal bones are quite separate and moveable, and, as 
they pass up, have a direction forwards to the palmar aspect of the 
carpus. ‘These two fingers are associated together in their move- 
ments, and can be moved independently of the rest of the hand, 
but there is a tendency to flex the other fingers at the same time. 
In general grasping, the thumb and sixth and seventh digits oppose 
the other four and clasp down upon them. The hand is flat where 
the ball of the thumb should be.* 
* A somewhat similar case, in which the duplicity of the hand was more 
complete, with a rudimentary condition of the thumbs, by Mr J. Jardine
