diseased, and the reservation for their solo use of particular 

 stable utensils. In the treatment of these nasal discharges 

 little or no good will result unless the means employed are 

 directed with the view of combating both the local and general 

 diseased condition. 



The horse ought to be laid aside from work, and placed on 

 good and liberal diet, and under the influence of correct 

 sanitary conditions. Therapeutically, the most successful con- 

 stitutional treatment I have found to be the exhibition of 

 arsenic or salts of iron, or arsenic and sulphate of iron com- 

 bined with yellow resin, given alternately; The arsenic can 

 be very readily administered as Fowler's solution, half a fluid 

 ounce morning and evening, in the food or drinking-water, 

 while from half a drachm to one drachm of the powdered 

 sulphate of iron combined with half a drachm of powdered 

 yellow resin can be given daily in the food. Others, I know, 

 recommend as very beneficial small doses of from one to three 

 grains of powdered cantharicles combined with copaiba, made 

 into a bolus with linseed-meal, and administered once or twice 

 daily. 



As local ajDplications the astringent tonics of the mineral 

 salts, as the sulj)hate or chloride of zinc or sulphate of copper, 

 varying in strength from five grains of the zinc chloride to 

 forty grains of copper sulphate to the fluid ounce of water, have 

 been followed with probably as much benefit as aught else. 

 There is probably less merit in the choice of the individual 

 material for this purpose than there is in the mode of its 

 application ; the difficulty being in every case to have the 

 liquid regularly distributed over the whole surface of the nasal 

 membrane, so that no part shall escape being bathed Avith the 

 solution. 



This difficulty can only be overcome by tact, patience, and 

 perseverance. The two methods usually adopted are that of 

 its distribution by means of an ordinary enema syringe, or 

 through the use of Re3''s nasal funnel. Each of these has 

 its special advantages, and, under certain circumstances, either 

 is efficacious. Besides the irrigation of the nasal membrane 

 with such solutions as indicated with the view to restore tone 

 and healthy functional activity, the use of these same or other 

 agents in the form of atomized fluids or solids is alwaj's de-
