Quote from ‘A Syllabus of Certain Topics of Logic’
The totality of all the lines of identity that join one another is termed a ligature. A ligature is not generally a graph, since it may be part in one area and part in another. It is said to lie within any cut which it is wholly within.
Peirce, 1903, p. 22; CP 4.416
