lead 30 grains, laudanum 2 teaspoonful?;, rain water — boiled and 

 cooled — 1 pint), applied with a soft cloth kept wet with the lotion, 

 and hung over the eye by tying it to the headstall of the bridle on the 

 two sides. If the mucous membrane lining the lids is the seat of little 

 red granular elevations, a drop of a solution of 2 grains of nitrate of 

 silver in an ounce of distilled water should be applied with the soft end 

 of a clean feather to the inside of the lid twice a day. • The patient 

 should be removed from all such conditions (pasture, faultj^ food, 

 exposure, etc.) as maj^have caused or aggravated the disease, and from 

 dust and irritant fumes and gases. He should be fed from a manger 

 high enough to favor the return of blood from the head, and shoidd 

 be kept from work, especially in a tight collar, which w^ould prevent 

 the descent of blood by the jugular veins. His diet should be laxa- 

 tive and nonstimulating (grass, bran mashes, carrots, turnips, beets, 

 potatoes, or steamed hay), and an}" costivcness should be corrected by 

 a mild dose of raw linseed oil (1 to 1} pints). In cold weather warm 

 blanketing may be needful, and even loose flannel bandages to the 

 limbs, and heat should never be sought at the expense of pure air. 



(2) In inflammations due to local irritants of a noninfective kind, 

 a careful examination will usually reveal their presence, and the first 

 step must be their removal with a pair of blunt forceps or the point of 

 a lead pencil. Subsequent treatment v,ill be in the main the local 

 treatment advised above. 



(3) In case of infective inflammation, there will often be found a 

 prick or tear by which the septic matter has entered, and in such case 

 the inflammation will for a time be concentrated at that point. A round 

 or conical swelling round an insect bite is especially characteristic. A 

 snake bite is marked by the double prick made by the two teeth and 

 bj^ the violent and rapidly spreading inflammation. Erysipelas is 

 attended w4th much svrelling, extending beyond the lids, and causing 

 the mucous membrane to protrude beyond the edge of the eyelid 

 (chemosis). This is characterized by a bright, uniform, rosy red, dis- 

 appearing on pressure, or later by a dark, livid hue, but with less 

 branching redness than in noninfecting inflammation, and less of the 

 dark, dusky, brownish or yellowish tint of anthrax. Little vesicles 

 may appear on the skin, and pus may be found without any distinct 

 limiting membrane, as in abscess. It is early attended by high fever 

 and marked general weakness and inappetence. Anthrax of the lids is 

 marked by a firm swelling, surmounted by a blister, with bloody serou- 

 contcnts, which tends to burst and dry up into a slough, while the sur 

 rounding parts become involved in the same way. Or it may show as 

 a diffuse dropsical swelling, with less of the hard central sloughing 

 nodule, but like that tending to spread quickly. In both cases alike 

 the mucous membrane and the skin, if white, assume a dusky brown 

 or yellowish brown hue, Avhich is largely characteristic. This may pass
