DISEASES OF THE DOMESTIC ANIMALS 



Counter-irritation externally with mustard paste or turpentine 

 stupes is valuable in mucous or hemorrhagic enteritis. In the latter, 

 tannic acid (5ii) should be prescribed every three or four hours with 

 laudanum (§i-ii). 



Ergotin (gr. 30-40 for adults; gr. 5-10 for young animals) 

 may be injected under the skin also, if the bleeding does not soon 

 cease. Strychnine subcutaneously, and alcohol by the mouth, are 

 demanded to relieve exhaustion, together with the use of normal 

 salt solution intravenously or under the skin. 



Boiled milk, raw eggs, with wheat or barley flour gruels, and 

 cooked roots, may be allowed. 



Entropion. 



This is a condition in which the edge of the eyelid is turned 

 inward against the eyeball. It follows trachoma and contraction of 

 scar tissue of the palpebral conjunctiva; it also may be due to 

 wounds or burns. A spasmodic form may originate from photo- 

 phobia. Entropion is more frequent in dogs. The chief harm pro- 

 duced by entropion is the rubbing of the eyelashes against the eye- 

 ball (trichiasis) and consequent inflammation of the cornea. 



Treatment.— -In mild cases, with a few inturned lashes, these 

 may be pulled out at frequent intervals. The application of several 

 coats of collodion may cause eversion of the lid when the collodion 

 dries and contracts. In the lower lid the method of Theobald, by 

 which the lid is everted by means of contraction of an eschar pro- 

 duced by caustic, may be used. A pencil of caustic potash, sharp- 

 ened to a point by rubbing it on wet blotting paper, is employed. 

 The lid is drawn away from the eyeball and held on the stretch. 

 Then the point of the pencil is rubbed along a line about an J^ of 

 an inch away from the lid margin, and parallel with it for the 

 greater part of its length, a number of times. After the caustic 

 has spread out somewhat its action should be stopped before the lid 

 is released by bathing it with equal parts of vinegar and water.
