(Plate 150 ASEPTIC SURGICAL TECHNIQUE. XV.) The supply of light must be abundant. Electriclights should be provided for night work, and a mova-ble lamp is needed for throwing light into the depthsof a wound. One-half of the bulb of such a lampshould be silvered like a mirror on the inner surface,to act as a reflector. The same hemisphere is opaqueon the outside, so as to shield the operators eyes fromthe light. (Fig. 26.) A gas supply and fittings for Bunsen burners arenecessary.
