and liiiiig over the eye by tying it to tlie 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 ^yith the soft end 

 of a clean feather to the inside of the lid twice a daj'. The patient 

 should be removed from all such conditions (pasture, faulty food, 

 exi)osure, etc.) as may have caused or aggra Abated the disease, and from 

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

 higli enough to favor the return of blood from the head, and should 

 be kept from work, especially in a tight collar, which would prevent 

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

 tive and non-stimulating (grass, bran mashes, carrots, turnips, beets, 

 XDotatoes, or steamed hay), and any costiveness should be corrected 

 by a mild dose of linseed oil (1 to Vr 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 non-infective kind, 

 a careful examination will usually reveal their j)resence, and the first 

 step must be their removal with a pair of blunt f orcex^s or the point of a 

 lead i3encil. Subsequent treatment will be in the main the local treat- 

 ment 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 jjoint. 

 A round or conical swelling round an insect bite is especially charac- 

 teristic. A snake bite is marked by the double prick made by the 

 tv>'0 teeth and by the violent and rapidly spreading inflammation. 

 Erysipelas is attended with much swelling, extending beyond the lids, 

 and causing the mucous membrane to x)rotrude beyond the edge of 

 the eyelid (chemosis). This is characterized by a bright, uniform, 

 rosy red, disappearing 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 

 liigh fever and marked general weakness and inappetence. Anthrax 

 of the lids is marked by a firm swelling, surmounted by a blister, 

 with bloody serous contents, which tends to burst and dry uj) into a 

 slough, while the surrounding parts become involved in the same way. 

 Or it may sliow 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, which is largely characteristic. 

 This may i^ass into a black color by reason of extravasation of blood. 

 There apjpears early great constitutional disturbance, with much 

 prostration and weakness and generalized anthrax symptoms.
