continually scratching them. If this is left unchecked, the 
amount of irritation produced on the inflamed part gives 
. tise to a serous exudation along the margin of the flap, and 
ulceration quickly follows, leaving a thickened irregular 
crusted edge. 
Treatment.—Immediately symptoms of canker are ob- 
served, a dose of aperient medicine should be administered, 
and warm fomentations applied to the part. Where exuda- 
_ tion has taken place, all extraneous matter should be gently 
removed with warm water, and mild astringents applied to 
the sore surface.. The following is a useful lotion :— 
ASW: weiss J shomres ahoraaielena alee 5 grains. 
WineGar ics sccnicessissaate 1 drachm. 
INGU A ccaucasedae ees eeiana hs I ounce. 
To be applied twice or three times a day. Or a drachm 
of oxide of zinc to an ounce of vaseline may be used with 
benefit. 
When the case will not yield to this treatment, and when 
ulcers have formed, and show a tendency to spread, I find 
occasionally touching the parts with nitrate of silver after 
‘washing is of great service; and when the eschar is detached 
either of the following lotions may be applied with a camel- 
hair brush :—

~ In obstinate cases, when the cartilage becomes diseased, 
‘and remains, in spite of all that can be done, ‘persistently 
so, it will be advisable to remove that portion of the flap 
‘beyond the line of disease; but only in an extreme case 
Should this be done. If drapty thickened, Painting with 
5 iodine will suffice. -
