    in iced water or on a block of ice, and laid upon the lids ; and by leeches. Cold is not to be used to any other form of iritis. Congenital irideremia (absence of iris) is occasionally seen, and is often associated with other congenital defects of the eye. Coloboma of the iris (congenital cleft in the iris) gives the effect of a very regularly made iridectomy. It is al- ways downwards or slightly down-in, and usually, but not always, symmetrical. There are many varieties in degree, and sometimes there is nothing more than a sort of line or seam in the iris. It often occurs without coloboma of the choroid. Persistent remains of the pupillary membrane have sometimes to be distinguished from iritic adhesions. They occur in the form of thin shreds or loops of tissue, in color resembling the iris, to the anterior surface of which, close to its pupillary border, they are attached. They are longer and slenderer than posterior synechias, and are not attached to the lens-capsule.1 In one remarkable instance I saw well-marked remains of this membrane complicated with equally unequivocal iritic adhesions in a case of acute iritis in a man. 1 When remains of pupillary membrane are complicated with old iritic adhesions in children, there has probably been intra- uterine iritis.
