After this inflammation a hard fear-like ridge Is left on the edge 

 of the eyelid, which fcratches and inflames the eyeball, and be- 

 comes a very troublefome difeafe. 



The Turkifa ladies are faid to colour the edge of the eyelafh 

 with crude antimony in very fine powder, which not only gives 

 luftre to the eye, as a diamond fet on a black foil, but may pre- 

 vent extraneous light from being reflected from thefe edges into 

 the eye, and thus ferve the purpofe of the black feathers about 

 the eyes of fwans, defcribed in Seel. XXXIX. 5. 1. and may 

 alfo prevent the edges of the eyelids from being inflamed by the 

 frequent ilimulus of tears on them. Black lead in fine powder 

 might be better for all thefe purpofes than antimony, and might 

 be put on with a camel's hair brufn. 



M. M. Mercurial ointment fmeared at night on the edges 

 of the eyelids. Burnt alum fixty grains, hog's greafe half an 

 ounce, well rubbed into an ointment to be fmeared on them in 

 the night. Cold water frequently in the day. See Oafs II. 

 1. 1. 8. 



4. Hordeolum. Stye. This inflammation begins either on 

 or near the edges of the eye-lids, or in the loofe fkin of them, 

 and is fometirnes very flow either in coming to fuppuration or 

 in difperfing. The fkin beneath the lower eyelid is the mod 

 frequent feat of this tumor, which fometirnes never fuppurates 

 at all, but becomes an encyfted tumor : for as this fkin is very 

 loofe for the purpofe of admitting great motion to the eyelid, the 

 abforbent power of the veins feems particularly weak in this 

 part ; whence when any perfon is weakened by fatigue or other- 

 wife, a darker {hade of colour is feen beneath the eyes ; which 

 is owing to a lefs energetic action of the abforbent terminations 

 of the veins, whence the currents of dark or venons blood are 

 delayed in them. This dark fhade beneath the eves, when it is 

 permanent, is 1 afymptom of habitual debility, or inirritability of 

 the circulating fyftem. See Clafs I. 2. 2. 2. 



M. M. Smear the tumors with mercurial ointment, moiften 

 them frequently with ether. To promote their fuppuration they 

 may be wounded with a lancet, or flit down the middle^or they 

 may be cut out. A cauftic leaves a large fear. 



5. Paronychia fuperficialis. Whitlow. An inflammation a. 

 bout the roots of the nail beneath the fkin, which fuppurates 

 ^without fever, and fometirnes deftroys the nail ; which is, how- 

 ever, gradually reproduced. This kind of abfeefs, though not 

 itfelf dangerous, has given opportunity for the inoculation of 

 venereal matter in the hands of accoucheurs, and of putrid mat. 

 ter from the dilTeclion of difeafed bodies ; and has thus been the 

 caufe of difeafe and death. When putrid matter has been
