Hemorrhage is usually very slight, owing to the use of adrenalin,but if any occurs it must be perfectly controlled before leaving thecase, as it may increase as the effects of the adrenalin pass of: Larynx and Trachea.—Any applications to the larynx is best pre-ceded by a preliminary spraying with a 2 to 5 per cent, solution, havingthe patient inhale at the time, preferably using graduated bottles. The superficial anesthesia secured in this way will permit of theeasy use of the swab later, which is used with a 20 per cent, solution. 1 ^^^^^^^Hj ^^ M 9e 1* & * mj\.

In all operations upon the above-mentioned parts, where the pro-cedure is at all protracted, the operator is warned of returning sensi-bility by the return of vascularity and oozing of the parts, which al-ways precedes the return of sensation and affords time for the applica-tion of additional anesthetic.
