470 DISEASES OF THE LARYNX. 



ployed as tlie medmm through which the medicine is conveyed 

 into the system. Such a mixture as the compound belladonna 

 and camphor electuary we have already advised for similar 

 conditions is very good ; it may be administered in moderate 

 quantities two or three times daily, along with the febrifuge 

 powders. 



Of local applications, which are always productive of good, 

 the chief is the assiduous use of the inhalation of hot-water 

 vapour ; this may be simple, and generated by pouring hot 

 wajter over chopped hay or bran contained in a nose-bag ; or 

 it may be medicated by pouring a little of such agents as 

 chloroform or sulphurous acid, or some liquid preparation of 

 iodine, conium, or opium, over the material contained in the 

 bag. In the employment of fumigation in cases of laryngitis, 

 great care is needful in carrying out the details, seeing that 

 with the extremely irritable condition of the parts there is 

 great liability to injure the horse, and particularly to induce 

 needless coughing or suffocation. 



Externally, over the region of the larynx, when pam or 

 swelling is considerable, it is desirable to have recourse to 

 warm- water applications ; these are carried out either by 

 means of poultices, or, what is easier, by cloths saturated 

 with hot water and wrapped around the throat, or, as being 

 capable of retaining for a longer period both heat and 

 moisture, tow or cotton-wool soaked in hot oil, and retained 

 by means of a hood or appropriate bandaging. When not 

 sufficient in a day or two to alleviate the urgency of symptoms, 

 these local appliances may be removed, and the parts receive a 

 moderate vesication with a liniment of cantharides ; this, how- 

 ever, I have not found to be so safe or beneficial a jDractice as 

 the assiduous employment of heat and moisture. When the 

 presence of saliva in the mouth is troublesome, either because 

 of its quantity or quality, the employment of a gargle, as a 

 solution of alum or sulphurous acid, nitrate of potash, common 

 salt, or tannic acid, will ahvays be advantageous and grateful 

 to the patient. 



Whenever the dyspnoea is considerable, we must not forget 

 the possibility of suffocation ; the animal ought to be watched, 

 and should the respiration become so impeded that restlessness 

 and anxiety of the animal are attractive, we ought not to risk
