same remarks apply to many other forms of disease, which show* 

 how important it is that stables should be properly ventilated. 



Symptoms. — The skin in those parts where the affection is lo- 

 cated shows on its surface small elevations, known as papulae ; but 

 they are difficult to discover in some horses, as they are of the same 

 tint as the skin. After awhile the rubbing tears away the summhd 

 of the papula?, and a secretion exudes which soon forms very minute 



scabs. 



During the past four years the disease has prevailed very exten- 

 sively among army horses, and it usually proved very obstinate, 

 from the fact that very few of the army farriers understood its 

 true nature ; neither were they acquainted with the modus operandi

 rub the affected regions dry, and lubricate the <«arae with a por- 

 tion of the following : 



No. 39. Kerosene oil 4 oz. 



Pyroligneous acid 12 oz. 



Mix. 



It is usually good policy to put the patient under a course or 

 alterative treatment; therefore the author recommends that he 

 have, daily, thirty grains of iodide of potass, dissolved in four 

 ounces of water, to be given in the form of drench, every day, un- 

 til tl*e disease has disappeared. 



Poll-evil 



The name of this disease originated in England, in consequence 

 of it being more prevalent in that country than in some others ; 

 hence, was a great evil, and occurring about the nape of the neck 

 or region of the poll, it was called " poll-evil." Much of the poll-
