The surgeon, provided with forceps,holds the moxa in one hand, and with the other fixes the mouth of thebellows, or the point of the tube, in order to be enabled to regu-late it conveniently, while an assistant puts the instrument into 300 NEW ELEMENTS OF OPERATIVE SURGERY. action. If the current of air should fall constantly upon the samepoint of the moxa, the burn would be made in an irregular man-ner. We must proceed, therefore, in such way that the beak of the (Fig. 168.). beIlow;s corresponds successively to all the points on the burningsurface. When the fire reaches to about three lines from the skin, it be-gins to occasion a little pain. This pain afterwards becomes moreand more acute, until the eschar is formed ; that is, until the cylin-der of cotton is entirely burnt. At the moment when the fire comesin contact with the teguments, there is heard a snapping noise,(petilleme7it,) or a species of crackling, (cr^aquement,) altogether pe-culiar, and caused by the skin becoming crisped and split, (^e fen-dille.) It is proper, during this operation, that the neighborhoodof the parts should be covered by linen, to protect them from thesparks and particles of fire scattered about by the action of thebellows. The pain which results from the application of the moxa, gene-rally less acute than the patients expect from it, does not cause CAUTERIZATION. 301 them to cry out, until the burning approximates the layer of themoxa
