In the first volume I complained, that both in England and France, all the flexible gum catheters are made straight, and that it requires a long time before they gain a set in a curved form, by being kept upon a curved iron stilet; that even after a period of ten years, they shall accjuire it so imperfectly, that when the stilet is removed, before they can be passed into the bladder, they have become nearly straight, and that the part next the point, is that which most reluctantly retains the curve ; added to this, in giving these catheters the curve, almost all those that have two openings near the point, have one of them spoiled in the attempt, if not both ; and when there is only one, to prevent this accident, it is necessary to keep the aperture upon the curved part of the instrument, the part* of all others, on which it should not be, as it must come in contact with the lower surface of the urethra, and by its edges, be grasped at the neck of the bladder, or lacerate the middle lobe of the prostate gland, even when it does not project beyond the surface, and in a still greater degree in proportion as it rises above it. These defects in the flexible gum catheters are great, when the instrument is of a small size ; but
