OBJECTIVE FIKING.

its dried pellicles or crusts. On the second or third day an ia- 

 flammatory swelling is developed, and all the symptoms of ordin- 

 ary firiag are manifested, and after three or four weeks the reso- 

 lution is complete. 



If the firing has been too severe, the serous secretion becomes 

 very abundant, and the inflammatory swelling increases rapidly and 

 becomes warm and painful. Towards the fifth or sixth day the 

 skia becomes black, dries up, shrinks, is raised in large patches, 

 and sloughs off, leaving a broad surface, covered with large granu- 

 lations, very slow to cicatrize. One great advantage which objec- 

 tive cauterization can claim over ordinary firing is, that when prop- 

 erly performed, it leaves no blemish whatsoever. 



Deep Cautebization. 



The cauterization which is carried beyond the thickness of the 

 skia and penetrates the subcutaneous structures, receives this 

 designation. 



The manner in which the cautery is inserted into the tissues, 

 and the length of time it is allowed to remaiuia contact with them, 

 have justified the division of this kind of cauterization into rapid 

 deep, and inherent, or disorganizing cauterization. 



Rapid Deep Cauterization. 



This is the comparatively recent mode known as needle firing, 

 inasmuch as it consists in the insertion of elongated sharp, needle 

 shaped cauteries, heated to a Hght red, Urbain Leblanc is credited 

 with the introduction of this species of instrument and is the
