The Ligaments wherewith the Jonctures of the Bones are covered, together with other things, incompassing or adhering to these Bones, swell and subside, in proportion as the respective Members are bent, or extended; that is, they swell, and dilate withinside the Angle, formed by the bend of the Members, and at the same time, are stretch'd, and lengthen'd without side the said Angle of the Bend: the middle parts found in the bend, or between the outer or inner Angles, partaking of the Diminution of the one, or Dilatation of the other; but in a greater, or less Degree, as they are nearer, or more remote from the said Angles of the Joncture.
