examples where it begins with a double twist. I therefore (some- 
what irregularly) propose calling this position 4. It is obtained as 
follows: Wind a turn of the string around top of left index finger 
and maintain in position with thumb. Place the two index fingers

back to back, and insinuate the top of the right one into the loop, 
at back of left index, from its proximal side, steadying the string 
with the thumb during the process. Now rotate the fingers inward 
(i. e., toward you) and upward; let go the thumbs, and draw the 
hands apart. The resulting figure consists of a proximal and distal 
loop, i. e., of a radial proximal and distal string, and of an ulnar 
proximal and distal string, the two latter being crossed.
