134 Roaring in Horses, 



way of treatment for Eoaring, unless we choose to try 

 iodine ; it may either be given internally, or employed as an 

 ointment, or used in both ways. I have not yet myself had 

 an opportunity of making trial of it."i Trasbot has given 

 iodide of potassium with good results, and I have also em- 

 ployed it, alternately with arsenic (Fowler's solution), with 

 excellent effect in some cases in which Eoaring was recent. 

 Zundel has tried this treatment, and lauds it highly.- 



Strychnine, given internally, and also applied hypoder- 

 mically over the larynx, has been favourably spoken of by 

 several Continental veterinary surgeons. It has also been 

 employed to discover whether Roaring may be really due to 

 paralysis of the abductor muscle, and whether the muscle 

 yet possesses any contractile power, by injecting it beneath 

 the skin over the left side of the larynx. 



Electricity, in the form of Faradisation, I have employed in 

 two cases, which perfectly recovered.^ It was tried, in con- 

 junction with the administration of iodide of potassium, 

 alternated with Fowler's solution of arsenic, upon the Dake 

 of Westminster's Ormonde, and it certainly appeared to 

 have the effect of preventing an increase of the noise, and 

 consequent distress in breathing of that grand race- horse. 

 It might be claimed, I think, that it assisted him to achieve 

 the victories of his final year on the turf; and it would, in 

 all probability, have kept him a successful horse during the 

 following year. For in Ormonde, when I first recom-

 appears to be serviceable in our own species, when similarly affected. 

 Lennox Browne, for instance, gives the case of a lady who consulted 

 him for severe attacks of hoarseness and dyspnoea. A careful examin- 

 ation led to the conclusion that there was congestion and paralysis of 

 the left vocal cord, due to enlarged bronchial glands pressing on the 

 recurrent nerve. Under the influence of doses of iodide of iron, as 

 well as external counter-irritation, the patient greatly improved. — •
