A little external to it, on each side, two curved lines will be observed extending from the sides of the chest to the pubis, and bounding the recti muscles; these are the linese semilunares. Some transverse lines, lineae transversae, three or four in number, connect the linese semilunares with the linea alba. The Linea semilunaris was the situation formerly chosen for the operation of tapping the abdomen in dropsy, para- centesis abdominis. But being merely the outer...
