![quantity of air in the dilator and reservoir together, makes the loss immaterial. Other substances impermeable to air, such as caoutchouc, may be sub- stituted for the perishable gut; and a spring placed on the membranous tube would not only increase the pressure as explained at page 96, but by an adaptation for the purpose, might serve, on with- drawing the dilator, as a tube to facilitate the ex- traction of the stone. A spring from its equal pressure might, itself, answer better as a dilator in such cases, than any of the steel instruments that have been employed. Instead of the common stone forceps, a modification of Hunter's forceps may be used, as means of easy extraction only, and not of further dilatation, is required.] Fig. V. is the Double Catheter, for injecting the bladder in cases of irritation of it, or contraction, and for the solution of stone : it is exhibited on a reduced scale. /, is the reservoir of the liquid to be injected ; cl, the flexible tube, commencing at the stop-cock e, by which the liquid is conveyed to the inner catheter a, which then carries it into the bladder, opening Sita;b,h, Z>, is the outer catheter, by which the](https://iiif.wellcomecollection.org/image/b21987440_0263.jp2/full/800%2C/0/default.jpg)
