The spools of silk arethen again boiled in a 1-1,000 bichlorid of mer-cury solution. Various sizes of silk may bearranged on spools in a glass jar arranged asshown in Fig. 58, a very convenient method ofhandling the material. The albumin of thesilk forms a chemical union with the mercury,which is slowly extracted by the fluids of thecirculation in the body. The mercury grad-ually disappears from the suture in from five to ten days. Haeglerdoes not believe that the small amount of mercury present in the suture destroys bacteria, but checks their Fig. 57.—Silk onSpools. (Bryant.) 100 SUTURE AND LIGATURE MATERIAL Silk, on general principle, should not be used for ligatures orburied sutures. It is being less and less used as the art of pre-paring absorbable suture material becomes perfected. It has a distinct field of usefulness in intestinal surgery. Forthis purpose, a very fine grade of silk is used,and should be dyed black so as to permit ofcloser scrutiny when being placed in situ. Theoperative field is apt to be bloody, and whitesilk soon takes on the color of the medium inwhich it is being used. If a reliable absorbablesuture material of sufficient tensile strength andas great pliability as silk were devised, an ideal^ N,,,,JJIliNll intestinal suture would be achieved.
