    Salmons Improved Catheters and Bougies. into the next bead above it; D, a fine double wire or string passing thro’ the tube and all the beads, and through the eye in the terminating bead, thereby keeping the whole together; E, cork fitted to the mouth of the tubular stem, which cork being put in fastens the thread and keeps the beads together, and this cork having a hole in it will admit the point of a syringe or 5 other instrument for injecting any liquid into the bladder, or any part of the urethra, according to the length of the instrument, which may be regulated at pleasure by the number of pieces introduced on the thread or wire. From this description it must be manifest that, when the wire or string D is some¬ what tightened, all the beads will be brought in contact, and form one flexible 10 tube to be passed into the bladder, and that when so passed the urine will pass by the flattened sides of the terminating bead, and along the inside of the beads and tube, or any liquid may be injected by the same course. Fig. 2, straight metalic bougie or probe. A, stem, with head to denote the upper side, either to the sight or touch; B, joint in A, to which the pieces 15 C, C, C, are jointed and pinned, and the joint B should have play both upwards and downwards, so as to work as much as ninety degrees of angle; C, C, C, straight pieces jointed to move upwards but not downwards, so as to form upwards such curve as may be required; D, terminating joint turned up at the end, so as more readily to enter the splimeter of the bladder. 20 Fig. 3, the same in its curved shape as passed through the urethra and into the bladder. From this view of the straight instrument it must appear that, although it will pass, it does not so correctly assume the shape of the curve and the sudden turning up into the bladder, as if it were made of curvilinear joints; but if the joints be short the objection to their being straight is not 25 material. Fig. 4, curvilinear metalic bougie or probe. A, stem, with head as before ; B, joint in A, having plenty of play, both upwards and downwards, as before; C, C, C, curvilinear pieces, jointed so as to move upwards but not downwards ; D, terminating joint as before. From a view of this only it may be observed, 30 that the curvature of the pieces will make them adjust more truly to the sudden turn into the neck of the bladder. Fig. 5, basis of pliant and resistable bourgies to be covered with any com¬ positions. A, a piece of platted line, commonly called Patent line, bound with thread or fine twine. This line being platted has no inclination to twist, and 35 is in itself perfectly pliant in every direction; but by binding of it with thread or twine, it becomes resistable, according to the degree of tightness with which it is bound. After a basis is prepared of any required size, as above described, to make the common wax bougie, they are thrown into boiling wax,;
