Diseases of the Respiratory Organs. 173 



In most cases, a thin pulp, made with mustard and 

 water, should be well rubbed in around the throat as soon 

 as the bowels respond, and covered up for two hours, but. 

 in the most severe, this may be preceded for a day or twc 

 by a linseed poultice. The diet throughout must be 

 green, soft mashes or roots. 



OEOUP. 



Especially seen in young animals (calves, lambs, foals,) 

 in cold and damp or high exposed localities. The symp- 

 toms are those of severe sore-throat (laryngitis) coming on 

 very suddenly with hard croupy cough and dry wheezing 

 breathing, worse at one time than another or heard only 

 at particular times of the day (morning, night,) when 

 spasms of the larynx come on. But the most characteris- 

 tic symptom is the formation of albuminoid false mem- 

 branes as white films or pellicles in the throat, and which 

 are discharged in shreds on the second or third day. 

 Fever runs very high, pulse ninety to one hundred, tem- 

 perature 107^, and even higher. 



Treatment. Give a warm, well-aired building, with 

 water- vapor set free in the atmosphere, if possible ; warm 

 clothing, a laxative (sulphate of soda) -nith antispasmodic 

 (laudanum, aconite, chloral-hydrate, lobelia) ; foUow up 

 with small doses of sulphate of soda, chlorate of potassa 

 and antispasmodics, giving each dose in well-boiled linseed 

 tea, slippery elm or marsh-mallow. Blister the neck ac- 

 tively (mustard, with or without oil of turpentine,) and, if 

 necessary, swab out the throat with a solution of nitrate 

 of silver ten grs., water one oz., applied by a small sponge 

 immo^'ably tied on a piece of whalebone. In the worst 

 cases suffocation must be obviated by opening the wind- 

 pipe in the middle of the neck and inserting a tube to 

 ^reathe through. In horses a ring must not be completely 

 cut across, but a semicircular piece cut out of ekch of two 

 adjacent ones. Sometimes stimulants (w'ne whey, car- 

 bonate of ammonia,) and tonics (gentian, . inchona,) musi 

 be used to sustain the failing strength.
