the recti muscles.* The gland of Harder, situated on 

 the outer face of the haw, is a reddish-yellow gland^ 

 covered by fibrous membrane and surrounded by fat. 

 Secretes a thick unctuous matter, which gains exit on 

 the inner face of the membrana by three or four open- 

 ings. 



DISEASES OF THE LIDS. 



Acute Blepharitis. — Abscess of the lids. Is an acute 

 phlegmonous inflammation of the lids ; usual cause is 

 of a traumatic nature. May accompany strangles or 

 follow it; adenitis simple. Will have great swell- 

 ing with the cardinal symptoms ; apt to have con- 

 junctivitis accompany this. May have fluctuation 

 early. This might go on to gangrene. If early enough, 

 cold applications to abort. If later, and suspect forma- 

 tion of pus, hot applications, and get the matter over 

 with. Of course, as soon as fluctuation is felt, open 

 freely and mahe the incision parallel with the lid bor- 

 der. Evacuate freely, using antisepsis and ascepsis 

 (and Boric acid solution is good and safe about the 

 eye) for patient and instruments. Do not use Hydrar 

 for instruments, as you'll dull the edge quicker than it 

 can be restored, and not more powerful than 1 to 5000 

 about the eye, unless great care is taken to prevent its 

 entrance into the conjunctival sac. May suture if 

 you think necessary ; compress bandage to insure first 

 intention.
