arm, one running on the membrane and one along each bone. At 
least two of these share in a network on the back of the carpus. 
Having reached the hand the ulnar artery runs obliquely across the 
palm to the cleft between the two sets of fingers, supplying the four 
normal fingers and the nearer side of the extra middle finger. The 
other branch of the brachial crosses the median nerve and runs, 
apparently superficially, to the outer side of the forearm. It supplies 
the little and ring fingers and the corresponding side of the middle 
finger of the supernumerary set. There is no anastomosis in the 
palm between the superficial branches of the two arteries. Each gives 
off a deep branch at the usual place, which form a deep palmar arch 
from which some interosseous arteries spring. There is also an arterial 
network over the front of the carpal bones. The arteries of the deep 
parts of the hand cannot all be seen. 
The Nerves. The ulnar nerve proper, pursues a normal course 
and supplies the palmar aspect of the little finger and half the ring 
finger of the normal hand. Near the wrist it gives off a very small 
posterior branch, which is not well preserved but which seems to have 
had less than the usual distribution. 
The median nerve is normal as far as the elbow, running to the 
inner side of the extra internal condyle. It is then lost in the dried 
Flexor sublimis, from which it emerges in two main divisions near 
the middle of the forearm. The inner of these soon divides into two, 
of which one supplies the adjacent sides of the ring and middle fingers 
and the other those of the middle and index fingers of the normal 
hand. The outer division of the median supplies the outer side of 
the index and both sides of the extra middle finger and one side of 
the extra ring finger. One of the branches to the index gives off 
a dorsal branch, and there is a doubtful one for the extra middle 
finger. The musculo-spiral nerve passes behind the humerus as usual. 
A nerve which is undoubtedly continuous with it emerges from the 
hardened muscles over the fused outer condyles. It seems to be the 
radial branch changed into an ulnar. It runs with the extra ulnar 
artery to the hand, and sending a deep branch into the palm, goes 
to the little finger. Its continuation is plain along the side of the 
little finger nearest to the ring finger. There is a detached branch 
on the other side of the little finger which in all probability came 
from it. The deep branch sends a twig along the metacarpal bone 
of the ring finger. It probably supplied the side of the ring finger 
left unprovided for, but this is uncertain. Assuming this to have 
been the case, each ulnar nerve supplies the palmar surface of one
