mouth till they reacli the swollen edges of the larynx, glide the bistoury 

 flatwise upon the finger, holding it as you would a pen. On reaching 

 the larynx direct the edge forward and upward, then after having 

 elevated the handle depress it gradually, at the same time pressing 

 gently upon the point. At first, a few punctures only should be 

 made, as by the aid of pressure two or three small incisions are suffi- 

 cient. They may easily be multiplied in the same way if judged 

 necessary. 



" These scarifications, says M. Lisfranc, produce a flow of the in- 

 filtrated matter and sometimes a slight oozing of blood, which effects 

 a salutary disgorgement. The cough excited by a few drops of serum 

 falling into the larynx, contributes much to diminish the swelling. 

 The immediate beneficial results of these scarifications might be par- 

 tially defeated, by their occasioning more or less inflammation of 

 the larynx and surrounding parts. In such a case recourse must 

 be had to general or local bleeding, which would soon disperse this 

 traumatic inflammation." 



It appears also, from M. Valleix's statement, that Professor Mar- 

 jolin has lacerated the oedematous edges of the larynx with a piece 

 of althea root, and M. Legroux with the nail of the index finger 

 sharpened for the purpose, and both with success.
