76 MANUAL OF MODERN FARRIERY. 
Experience must have taught many persons possessing a 
number of horses, that frequent instances have occurred of 
horses having been put into a straw-yard perfectly sound, 
coming out broken-winded. The food affording but little 
nutriment, the animals require to keep their stomachs always

their action being thereby restricted, a violent effort becomes 
necessary to effect respiration, and hence rupture of the 
partitions of the air-cells take place.

Calomel ... 1 drachm, 
Aloes ... 2 drachms; 
these to be made in the form of a ball, and administered 
twice a week, while the affection continues. 
Various degrees of broken-wind produce certain effects, 
which have each their technical designations by dealers 
andjockies. These are—

alleviating remedies—-for cure there is none—are gentle

that well-known sound when under exercise or labour. The 
following drench will be found of considerable benefit when 
cough accompanies this complaint:—
