.—The original experiments on intertraction in which serum coloured with eosin was imposed upon a heavier salt solution and uncoloured serum upon coloured salt solution were carried out in place walled "intertraction cells" made from two microscopic slides placed from 1 to 1⋅5 mm. apart and cemented together by plasticene or pitch. In experiments thus conducted the intertraction pictures obtained are complicated by changes produced by the surrounding fluid in the ascending and descending pseudopodial processes; and by diffusion of albumen and eosin, or eosin and salt outwards from the pseudopodial processes into the surrounding fluid. Moreover, certain significant features of the intertraction picture are only obscurely seen when they are viewed through too thick s sheet of fluid. It will be necessary here to describe a little more fully what is seen in intertraction cells.
