Chronic Nasal Catarrh. Nasal Gleet. Ozcena in the Horse. 89 



Among stimulants, cubebs, cayenne pepper and copaiba have a 

 stimulating and stjrptic effect on the mucous membrane and each 

 of these has been successfully used in such cases. Cantharides , 

 in five grain doses have proved even more successful, (Vines, 

 Percivall) . Sulphate of Copper in drachm doses in mucilage night 

 and morning has proved very efficient ( Sewell , Percivall ) . A rsen- 

 ious Acid has been employed with still better results. The dose, 

 of five grains, may be intimately mixed with a scruple of bicar- 

 bonate of soda and given daily in food.* 



But the most efficient tonic in these cases is arseniate of 

 strychnia. Its good effects may be secured by combining with 

 the above mentioned powders of arsenious acid and bicarbonate 

 of soda, half a drachm of powdered nux vomica for each dose.f 

 These powders will usually be taken in food, and may be contin- 

 ued for a month, or until the discharge ceases. 



In all cases the general health must be carefully attended to. 

 Keep the patient in a dry, clean, airy building without draughts 

 of cold air ; give moderate exercise in the open air ; and good 

 grooming ; and allow nutritious food of mildly laxative proper- 

 ties, — as occasional bran mashes and roots in winter and succulent 

 grasses in summer. 



Local Applications. These are the most important remedial 

 measures, and usually of themselves succeed in reestablishing a 

 healthy condition. 



The agents proving most useful are of an astringent nature, and 

 in obstinate cases one may be substituted for another as the last 

 appears to lose its effect. Sulphate of zinc, sulpho-carbolate of 

 zinc, or sulphate of copper in the proportion of half a drachm of 

 either to a quart of water, may be used, or if there is much foetor, 

 a solution containing a drachm each of carbolic acid and carbo- 



* In giving this agent, any redness or watering of the eyes, or colicy pain 

 should be carefully watched for, and when these premonitory symptoms of 

 poisoning are noticed the medicine should be at once suspended to be com- 

 menced a few days later in smaller doses. 



t Whenever nux vomica or its alkaloids, strychnia or brucia, are given, 

 increased irritability and nervousness should be -carefully watched for, and 

 especially any involuntary twitching of the muscles. On their appearance 

 the agent must be suspended and commenced a few days later in half the 

 former doses.
