I'lSEASES OF SHEEP. 9 



grains, rhubarb, one-eighth ounce, mixed with flour an 

 water or chamomile tea, given in one dose two or three time 

 a day. In some cases one-sixteenth ounce of chalk may t 

 added. 



COUGH. 



Cough is very common in sheep, even if not caused b 

 or accompanying lung worms, etc., probably because shee 

 are much exposed to the influences of the weather. Th 

 cough which we propose to consider here is of a drawlinj 

 metallic character, and is thus distinguished from coug 

 produced by other causes. In spring a large portion of 

 flock is sometimes troubled simultaneously with cough, an 

 generally no other symptom of sickness is present, excej 

 perhaps that the patients do not eat as much and are nc 

 as lively as usual. Cold drink, cold and wet weather, etc 

 are the most common causes of this trifling disease. Th 

 cough disappears easily if the causes are removed, and 

 salt-lick composed of sulphur, juniper-berries and commo 

 salt, given occasionally, facilitates the cure. 



LUNG WORMS. 



This disease (known also under the name "lung worr 

 cough") occurs almost exclusively in lambs during thei 

 first year, and very seldom later. Sometimes whole floct 

 are destroyed by it. At first the sick lambs are weak an 

 lazy, lose their liveliness, do not grow, become delicate an 

 lean, creep along and allow themselves to be caught wit!
