(not over 1 ounce a day divided into two parts and given in 

 water). AVhen tlie temperature gets down to 102°, stop internal 

 treatment, and treat locally 

 about as follows : It is nec- 

 essary to have a stall with 

 a soft bottom as saw-dust, 

 ashes, etc. Occasionally it 

 is best to dampen the ashes 

 a little during the day, and 

 rake them up so as to form 

 a yielding body to the feet. 

 Throw a little bedding over 

 it at night, and also during 

 the day to give the horse a 

 chance to lie down. 



Treatment. — Apply cool-

 cold swabs ; that is, cover 

 the feet with two or three thicknesses of blankets, and keep wet 

 with cold water. After the acute symptoms subside, blister. 

 The point is to lower the fever, and check the flow of blood to 

 the feet.

 membrane of the nasal chambers and cavaties of the head. It 

 consists in a congested or inflamed state of that membrane, giving 

 rise to a glairy discharge from one or both nostrils, and when the 

 head of the Avindpipe (larynx) is implicated, accompanied by a 

 cough. 



Causes may be classed under predisposing and exciting, as 

 the majority of young horses under five years of age may be said 

 to be predisposed to this affection. The exciting causes are sud- 

 den variations in the state of the temperature ; undue exposure to 

 cold when an animal is in a heated state, especially after a hard 

 day's work or drive ; standing in stables badly ventilated, or any 

 place exposed to cold draughts. Perhaps the most common cause 

 in young horses is placing them in warm stables in the fall of the 

 year immediately on taking them off the pastures. A sudden
