tion of one or two doses. The use of the seth. nit, should 

 cease when the pulse becomes fuller, and the potassae 

 nitr. may be persevered with. It is said that a pretty- 

 powerful opiate, as opii tr.,5i. — ^ii., 'combined with potassium 

 nitrate 5i., aqua q. s., will often succeed in arresting the 

 course of the disease, if administered at an early stage ; but 

 the above should never be given in any case where the 

 disease is well developed. 



Inhalations of steam are highly beneficial, relaxing the 

 mucous membrane and relieving the nasal irritation. A 

 close nose-bag should never be used, as the horse breathing 

 only through his nostrils would have his life endangered, 

 unless able to get a certain amount of pure air with the 

 steam. If the cough be troublesome, or shows a tendency 

 to become chronic, a stimulating liniment, as the am- 

 moniacal liniment, or a mild blister, may be applied ; and 

 a bolus, composed of equal parts of belladonna ext., cam- 

 phorse, and ipecacuanha, may be given once a day until 

 relieved. In this, as in all other respiratory affections, 

 purgatives are totally inadmissible. Should constipation be 

 present, as it usually is to a greater or less degree, order 

 food of a laxative nature, as soft mashes, containing linseed 

 meal ; or the condition may be relieved by a mild oleaginous 

 draught, as ol. lini., 5viii. — 5xii. ; or enemas of warm 

 water, with a little sodium chloride, may be given. If the 

 nasal discharge becomes chronic, potassium iodide should 

 be given night and morning in drachm doses, or ferri sulph., 

 5ii. — 5iii-5 ^^y ^6 given twice or three times daily; the 

 iron being also a valuable tonic. A favourite prescription 

 in England is as follows : Ferri sulph., 5ii. — 5iii. ; resinse, 

 5i. — 5ii. ; twice or three times a day. The nostrils should 

 be sponged several times daily, the eyes should also be 

 sponged gently if much inflamed or if discharging. A change 

 of food often hastens recovery — green food is highly bene-
