LEFT HAND OF ITALIAN IMMIGRANT 
The first joint of the little finger appears to have split in two at a very early stage in the develop- 
ment of the hand, with the result that two little fingers have been produced. This seems 
to be the way in which extra fingers and toes ordinarily appear in man. In this case the 
extra fingers are complete in joints and tendons, but often they are much more rudimentary.
