len glands; wait until 3^011 arc certain the swelling contains pus. The 

 formation of pus maj'^ be encouraged by the constant application of 

 poultices for hours at a time. The best poultice for the purpose is 

 made of linseed meal, with sufficient hot water to make a thick paste. 

 If the glands remain swollen for some time after the attack, rub well 

 over them an aj^plication of the following: Biniodide of mercur}^ 1 

 dram; lard, 1 ounce; mix well. This may be applied once every day 

 until the part is blistered. 



Sore throat is also a symptom of other diseases, such as influenza, 

 s.tranglos, purpura hemorrhagica, etc., which diseases ma}- be consulted 

 under their proper headings. 



After a severe attack of inflammation of the larynx the mucous mem- 

 brane may be left in a thickened condition, or an ulceration of the part 

 may ensue, either of which are liable to produce a chronic cough. For 

 the ulceration it is useless to prescribe, because it can neither be diag- 

 nosed nor topically treated by the nonprofessional. 



If a chronic cough remains after all the other symptons have disap- 

 peared, it is advisable to give 1 dram of iodide of potassium dissolved 

 in a bucketful of drinking water one hour before feeding, three times 

 a day, for a month if necessary. Also rub in well the preparation of 

 iodide of mercury (as advised for the swollen glands) about the throat, 

 from ear to ear, and in the space between the lower jaw bones. The 

 application may be repeated cver}^ third day until the part is blistered. 



SPASM OF THE LARYNX. 



The symptoms are as follows: Sudden seizure by a violent fit of 

 coughing; the horse may reel and fall, and after a few minutes recover 

 and be as well as ever. The treatment recommended is thus: Three 

 drams of bromide of potassium three times a day, dissolved in the 

 drinking water, or give as a drench in about a half pint of water, for 

 a week. Then give 1 dram of powdered nux vomica (either on the 

 food or shaken. with water as a drench) once a day for a few weeks. 



CROUr AND DIPHTHERIA. 



Neither of these diseases affects the horse. But these names are 

 sometimes wrongly applied to severe lar3'ngitis or phaiTngitis, or to 

 forage poisoning, in which the throat is paralyzed and becomes exces- 

 sivel}' inflamed and gangrenous. 



THICK WIND AND ROARING. 



Horses that are affected with a chronic disease that causes a loud 

 unnatural noise in breathing are said to have thick wind, or to be 

 roarers. This class does not include those affected with severe sore 

 throat, as in these cases the breathing is nois}^ onl}^ during the attack 

 of the acute disease.
