454 SYMPTOMS OF DISEASE OF RESPIRATORY ORGANS. ^ 



change of tlio bony walls of tlie nasal chambers, or with 

 abnormal growths, hard or soft in character, situated there, in 

 addition to the dyspnoea exhibited on exertion there is often, 

 even in moderate movement or at rest, a snuffling character in 

 the breathing, with repeated sneezings and a discharge of 

 mucus of a slightly frothy character, occasionally mingled 

 with blood. In such cases of abnormal growths in the 

 chambers we are much assisted in their detection by speculum 

 examination and by percussion. 



When the obstruction is ascertained to be either an osseous 

 tumour springing from the bony walls of the cavity, or a 

 fibrous growth attached to the soft tissues, known as a nasal 

 polypus, we are always justified in attempting the removal of 

 the offending body when this can be accomphshed with a 

 reasonable probability of success. 



When the lesion operating in the production of the charac- 

 teristic sound appears to be in the pharyngo-laryngeal region, 

 confirmation of the suspicion may be obtained by auscultation, 

 which during excited respiration will give the sound direct, 

 loud, harsh, and near. Having satisfied ourselves of the 

 locality of the lesion so far, we may, by examination with the 

 hand, discover whether any adventitious growth or deposit 

 exists likely to cause the embarrassed respiration. These, 

 when existing, must be treated according to the recognised 

 rules of surgery. 



When following a smart attack of catarrh, strangles, or in- 

 fluenza, the condition of roaring requires more discrimination 

 in dealing Avith it than at most other times. All these cases 

 are deserving of being for some time carefully observed, and of 

 having the benefit of medical treatment. Although it is not 

 advisable to throw such animals entirely idle, their Avork 

 ought not to be hard or oppressive ; and the diet should be 

 good, but not carried to repletion. 



The treatment, therapeutically, which I have found produc- 

 tive of most benefit, has been the daily exhibition of potassium, 

 iodide, and arsenic ; the former in drachm doses in the 

 morning, the latter three grains combined with three drachms 

 of bicarbonate of potash, or one fluid ounce of Fowler's solution 

 of arsenic in the evening. Both these medicines can be given 

 in the food or drinkinu'- water, and out>-ht to be continued for
